Hypertension: is it possible to donate blood with this disease, possible consequences. Can hypertensive patients donate blood? How safe is it? Blood pressure drop after donation

Last modified: August 24th, 2019 at 01:25 pm

Blood donation is not a direct obligation, but the right to help other people who find themselves in a difficult situation, sometimes on the verge of life and death. The procedure is allowed for adult healthy people who have been tested for HIV and other blood infections, and also do not have health restrictions, which include arterial hypertension. But some hypertensive patients claim that blood donation brings them exceptional benefits and improves their well-being. So, is it possible to donate blood with hypertension, and what risks does it carry for people suffering from this disease?

Hypertension is a frequent increase in blood pressure, with which blood presses on the walls of blood vessels. The normal indicators of blood pressure are considered to be 120/80, which may vary slightly, but there are no serious jumps. Increased pressure is considered in cases where the indicators rise to 140/90 mm. mercury column and above. At first this happens after the influence of negative factors, but then at rest.

Three stages of hypertension are divided: in the first stage, blood pressure can rise to 160/100 mm, in the second - up to 180/110 mm, in the third - up to 180/120 or more. Such high pressure causes negative changes in the internal organs and disrupts their functions, due to which the well-being and health of a person worsens. Hypertensive patients often suffer from dizziness, headache, severe weakness, pain in the heart and other symptoms, and constant jumps in blood pressure are fraught with rupture of the vessel and the development of a stroke.

Tip: many hypertensive patients, especially in the early stages of the disease, are unaware of their condition, so you need to pay attention to alarm signals and constantly monitor pressure, especially in adulthood.

Hypertension is not a death sentence, but people with this diagnosis have to make some changes in their lifestyle and avoid:

  • intense physical activity;
  • nervous tension and stress;
  • living in too hot climates;
  • abuse of caffeine, alcohol and other tonics.

Hypertension and denunciation are incompatible concepts. Blood sampling from people with high blood pressure is possible only for the purpose of diagnosis and is carried out under medical supervision.

Most people with hypertension are not even aware of their serious illness. It becomes known about him during the passage of a scheduled examination for employment, at an educational institution, a medical board in the army or at a blood transfusion station. And already in this case, many are wondering whether it is possible to donate blood with hypertension. Previously, bloodletting was used to reduce pressure. This procedure allowed to normalize the condition for a while, but later it was abandoned due to side effects and high health risks.

In the human body, a certain volume of blood circulates in proportion to body weight, and any loss of it is stress. People who are in good health and do not have chronic diseases do not tolerate blood loss so acutely. The blood is renewed, and the body quickly compensates for the shortage. A sick person has a hard time coping with a deficit, and even minor losses threaten serious consequences.

Hypertension is a contraindication for donation. You can donate blood at high pressure only for laboratory tests.

But even in this case there is a limitation for the analysis. The fence is done no more than 8 times a month, if necessary. Even a minimal deficit in blood volume negatively affects the well-being of hypertensive patients. Therefore, before and after testing, it is important to monitor (BP). In addition, for people with a sick heart, an ECG (electrocardiogram) procedure is mandatory. According to its result, it is possible to determine whether a person can hand over this biological material without consequences for himself. According to the cardiogram, they decipher the functional state of the heart muscle, the number of its contractions, and also observe whether there are consequences of hypertension.

What is the danger

The donation of biological material from a donor provides for the loss of blood in the amount of 10% of the total amount - about 450 ml. This procedure is serious and always undergoes a thorough examination before it. There are special criteria and allowable indicators according to which blood donors are selected. People with infectious diseases, chronic ailments are not allowed to the procedure. And also you can not donate blood after surgery.

They refuse to take blood for people with a tattoo, as an infection could get into their blood. With a hangover, you should also not go to a donor site - alcohol is toxic in itself, and the blood is no longer suitable for transfusion.

Hypertension and high blood pressure are among the contraindications. Only in case of urgent need and with acceptable blood pressure values, with the permission of a doctor, can one become a donor for hypertension.

The thing is that jumps in blood pressure cause discomfort and cause disruption of not only the cardiovascular system, but also other organs. For a healthy adult, the norm is considered to be blood pressure at the level of 120/80 mm Hg. A steady increase in it indicates hypertension. An accurate diagnosis can be made by additional studies: an ECG and maintaining a special one, where it is indicated when the indicators are elevated and when a lower level of blood pressure is observed.

The danger of blood loss with hypertension lies in the likelihood that a sharp jump in pressure will occur. This threatens the development of heart failure, hypertensive crisis and even hemorrhagic stroke. The pressure in the vessels can increase by 15-20 units as a result of a decrease in blood volume. Such fluctuations can threaten the life of not only hypertensive patients, but also harm the health of a person with chronic diseases of the internal organs, as well as if the pressure is low.

Why do you get tested for hypertension?

It is impossible to become a donor for hypertension except in special cases, and even then, only under the supervision of specialists. But to control your health, you must donate blood for research. A biochemical and general blood test allows you to determine the severity of the disease, and also serve the following purposes:

  • control the patient's condition;
  • choose the optimal treatment tactics;
  • identify the development of complications before they cause significant harm.


An important indicator for hypertension is such a value as hematocrit, it is first of all paid attention to. This indicator displays the ratio of red blood cells to the total amount of blood. If there are few of them, even a slight loss is already dangerous.

Hypertension, especially the one that has been tormenting for several years, negatively affects the work of all internal systems. Most of all, she and observe these deviations in the work of the body on the ECG. This is followed by the kidneys, so it is important to do kidney tests with a detailed analysis. Indicators such as creatinine and urea allow you to determine how much worse these organs began to work.

Equally important are electrolytes and glucose levels. Often, hypertensive patients have an imbalance of potassium and sodium or develop diabetes mellitus. Increased pressure affects the state of blood vessels and causes the development of atherosclerosis, so it is important to monitor lipid metabolism and cholesterol levels regularly. What tests need to be taken, the attending physician will tell. After receiving the results, he will determine whether it is possible to prescribe studies at elevated pressure.

How to donate blood for hypertension

If it becomes necessary to draw blood for donation purposes, it is important to be extremely careful and know how to go through this procedure correctly. Before manipulation, you need to measure blood pressure, make an ECG, and donate blood only with the permission of a doctor. After the procedure, it is important to monitor the condition of the donor in order to avoid consequences.

Before donating venous or capillary blood, the following studies are also carried out:

  • measure blood pressure;
  • monitor the frequency and rhythm of the pulse;
  • talk to the patient about his condition in general.

The same is important to do after blood sampling. A general analysis, like a biochemical one, is done on an empty stomach in the morning. With hypertension, this is very convenient, since at the beginning of the day, blood pressure indicators are quite stable.

A person may not know all his illnesses and disorders, therefore, before deciding to become a donor, the specialist always recommends: “First, take tests, ECG and measure blood pressure.” If the indicators are lowered, this does not mean that the person is healthy, and it is strictly forbidden to drink pressure-lowering drugs before the examination.

Donating blood is a rather serious procedure and not everyone can become a donor. There are certain criteria that allow you to determine indications and contraindications for sampling. First of all, this concerns the presence of certain diseases, especially serious ones such as HIV infection, AIDS, the presence of cancerous tumors or diseases of the cardiovascular system. With such indications, blood sampling is strictly prohibited, because otherwise you can harm not only yourself, but also the patient.

A disease such as hypertension also belongs to the category of prohibition. It is characterized by a constant or intermittent increase in blood pressure. Accordingly, in the presence of this deviation, with the exception of acceptable pressure indicators and the lowercase need for a donor. This will be discussed in this article.

Why is hypertension dangerous for blood donation?

Pressure surge always causes discomfort. This can be explained by the fact that the walls of the vessels of our body are under a certain pressure. This is the number with which blood presses on the walls of blood vessels. For example, when pressure is measured, two-digit indicators are obtained - this is 120/80. For an adult, this is the most optimal pressure at which you can feel good.

The first number shows systolic pressure, that is, the force with which blood presses on the walls of blood vessels after a heart contraction.

The second digit characterizes the pressure indicators in the intervals between heartbeats. The same can be said with certainty. That each person has a different pressure, but on average, in a calm state, it should not exceed 140/90.

There are also three stages of hypertension, which are respectively characterized by an increase in pressure. In the first stage, indicators within 160/100 can be considered the norm. The level can change during the rest of the patient or vice versa during physical exertion. As for the second stage, the indicators are slightly higher there, which in turn is characterized by other symptoms. These are numbers within 180/100, which can change during rest or exercise. With hypertension of the third stage, the highest rates can be counted. These are precisely those catastrophic figures in which a person must always keep his pressure under control. These are the limits of 200/115. The last stage is the most dangerous, since such hypertensive patients can not only donate blood, but also burden themselves with physical exertion or stress.

Almost the same symptoms are characteristic of all stages - headache, sleep disturbance, dizziness, pain in the heart, and severe vascular complications occur. Also for the third stage, a characteristic clinical picture in the form of damage to the heart and brain, which can lead to a heart attack. The kidneys, the fundus of the eye begin to suffer no less and, accordingly, complaints arise.

Can hypertensive patients donate blood?

The loss of any amount of blood for the body is some kind of trauma. Just a healthy person can tolerate it normally, and the patient will receive a significant blow. Therefore, only a healthy person who has undergone a number of relevant tests and some other examinations should categorically donate blood.

Hypertension is a fairly serious disease, so it can be said with accuracy that all hypertensive patients, regardless of stage, cannot donate blood. During the examination, you will need to take a general blood test, measure pressure and review the history of existing diseases. Therefore, the doctor will definitely not allow the patient for donation.

Without following a number of rules, you will not be able to be a donor:

With hypertension, the body experiences constant discomfort, since high blood pressure still affects health. If you give an additional push at the same time, then a person may have a heart attack, which will significantly worsen well-being. Any doctor can tell you about this, especially for the elderly. In most cases, a person does not immediately notice an increase or decrease in pressure.

Often we sin on bad weather conditions or temperature changes. Although in fact you can measure the pressure and see that its indicators change and in some way make themselves felt. Much worse for those people who do not feel pressure drops. This is very dangerous, because even at the highest pressure, the state of health will be satisfactory and it will be possible to continue to engage in either physical activity or something else that is so dangerous in such situations. Therefore, you can donate blood during pressure surges only for tests..

But do not forget that the analysis has its limitations. With hypertension, it is not recommended to donate blood for tests more than twice a week. Even the most minimal intervention can adversely affect the state of health with hypertension.

Why take a blood test for hypertension

Such an analysis is simply indispensable for hypertensive patients. After all, with the help of it, doctors manage to determine the condition, the disease, its main cause and the state of the organs that are under a lot of pressure. In this case, blood is taken from a vein on an empty stomach, as with all other tests. The presence of the necessary indicators is determined. It is also a great opportunity to choose the right treatment for the patient.

If the test results are not very high and the pressure is also within the normal range for the first stage of hypertension, then in exceptional cases it is allowed to donate blood as a donor. In such situations, the donor is taken under strict control and pressure drops are monitored for the entire time of the sampling itself.

There are several ways to restore blood volume after donation:

If the first symptoms of an increase or deterioration in the donor's well-being appear, the procedure is stopped. Such cases may occur when there is an urgent need for donation. For example, after severe blood loss during surgery or childbirth in a woman. Such emergencies are more than dangerous, and it is not always possible to find a suitable donor. Therefore, they take blood under strict control.

Who else can't donate blood?

This question torments almost every person who wants to help the sick and become a donor for him. For example, come once a month and leave blood for those who really need it. But, despite this, medicine has its own rules and limitations.

You can ignore some of the rules of blood sampling, but in no case by restrictions on donation. Categorically restricted are people who have: AIDS, syphilis, HIV infection, tuberculosis, viral hepatitis, complete lack of hearing and speech, hypertension, congenital or acquired heart disease, malignant tumors, endocarditis, total blindness, various lung diseases, stomach ulcers , pustular diseases of the stomach, myopia, psoriasis, trachoma and many others. Such diseases pose a danger not only to the donor, but also to the patient himself.

Together with the blood, the disease can pass to another, because all the smallest inflammatory bodies are present in the blood. In order to determine the presence of certain diseases, before taking blood, the donor undergoes a number of certain procedures for verification. And only after that it is allowed to be a donor.

Other diseases of the cardiovascular system

There are still some problems of the heart and its entire system that do not allow donating blood for donation. Along with hypertension, they also play a significant role, as they are quite serious and dangerous to health. You may not know about the presence of some of them, but it is better to double-check before taking blood so as not to harm your body even more. These are atherosclerosis, ischemic disease, defects and inflammation of the heart, and some vascular diseases. In such cases, death can often occur, so there can be no talk of donation. Such a patient himself needs help and taking many medications.

In medicine, there are quite a few cases when patients, not knowing their main diagnosis, decide to donate. This can turn into a tragic outcome for the patient. A long time ago, medical scientist Davydovsky called such diseases uncharacteristic of the environment, since with such symptoms a person cannot adequately adapt to progressive urbanization. It is urbanization that is associated with a person's lifestyle and is influenced by stressful situations. The ecology and some features of civilization also have a significant impact on health and well-being.

Benefits of donating blood in the absence of hypertension

You can talk a lot about the fact that the development of certain diseases is influenced by the image of a person or ecology. But the main focus is the individual disposition of a person. But, despite the many such factors, doctors argue that it is possible and necessary to donate blood, in the absence of such diseases.

Is it possible for hypertensive patients to donate blood - this is a question that potential donors ask. It is necessary to know that the composition of the blood in such a pathology is rarely disturbed, especially in essential hypertension. But the process of collecting it can be unsafe.

How is blood donation done?

Blood donation should be carried out in medical centers called "Blood Transfusion Station". There is a special equipment that allows you to painlessly and safely carry out the procedure.

During the sampling of the biomaterial, the patient is in a supine state. A catheter is connected to it, most often inserted into the cubital vein. Before the procedure, blood pressure must be measured, and if it exceeds 140/90 mm Hg. Art., then the medical worker refuses to take blood for hypertension.

After the delivery of the material, the person lies for 10 minutes, then gradually rises, his pressure is measured and offered a piece of chocolate or sweet tea. The material itself is sent for complex analysis. The procedure is debugged and absolutely safe for a healthy body. But many are interested in whether it is possible to pump out blood with hypertension?

Donating blood requires certain conditions to be met. Preliminary it will be necessary to undergo an examination of the body

Is it possible to donate material to hypertensive patients?

Patients-donors with the second and third degree of hypertension (AH) are prohibited from donating blood. Healthy people who weigh more than 60 kilograms and do not drink alcohol or other illegal drugs are allowed to be blood donors. The material of each donor after delivery is thoroughly checked.

Donation for hypertension (hypertension) is dangerous. This is because the rapid removal of blood from the venous bed increases the load on the heart. The pressure begins to fall, while the pumping function of the heart muscle increases. With GB 2 and 3 degrees, the vessels are changed, their elasticity is lost. Accordingly, their response to sudden pressure drops will also be slow.

Such manipulation leads to the development of tachycardia and possible ventricular fibrillation. A defect in the filling of blood vessels can lead to the development of collapse and cardiogenic shock. Sometimes a patient has a heart attack or stroke during a transfusion. If, however, the liquid is pumped out of the finger, and not from the vein, and the procedure is carried out more slowly, then the effect of reducing pressure is achieved. The strength of the heart muscle will also increase, which will serve as a prevention of heart failure.

After the blood sampling procedure in healthy people, the pressure decreases by 8-10 units of the mercury column, and in hypertensive patients there is a decrease in pressure by 20 units. It is important that the condition of the vessels, their elasticity, allows the liquid to be pumped out. With hypertension, you can take blood from a finger. Patients in this form are tested. The amount taken should be small so as not to cause an increase in cardiac activity.

Hypertensive patients should not donate blood, regardless of the stage of development of the pathology

After two or three days, the indicators on the tonometer will decrease, the number of erythrocytes and other formed elements will decrease. A state of hydremia will come, which will positively affect the patient's well-being. If you practice this method of pumping out with hypertension, then this will bring a positive effect. But a full-fledged donation with a fence of 300-400 milliliters is prohibited. The effect of hypotension after blood donation is noted for 4 weeks.

What cardiovascular pathologies do not allow donation?

In addition to hypertension, there are diseases of the cardiovascular system that do not allow the possibility of being a donor.

With these pathologies, sampling in the center or at the blood transfusion station is prohibited:

  • atherosclerotic vascular lesions;
  • malformations of the heart;
  • tendency to thrombosis;
  • cardiosclerosis;

Along with hypertension, there are other diseases of the cardiovascular system in which donation is contraindicated

Patients are recommended a sparing or limited sports regimen. Blood donation refers to above-average physical activity and often leads to an exacerbation of the underlying pathology and causes death. Before taking the material, you need to be examined by a therapist, and find out if there are any such pathologies.

The benefits of donating biomaterial

Blood donation can be carried out by people without diseases in the cardiovascular system. The body regularly renews the composition of this tissue and all cells on its own, but the surrender of components or whole fluid is considered a beneficial action.

Donation is allowed for men no more than 5 times a year, women can donate material no more than 3 times a year. Doctors recommend taking a break between donations of 6 months, then the liquid will be restored in composition and volume. Women are allowed to donate less blood, they have regular monthly blood loss (menstruation).


Donating blood requires certain conditions to be met. You will first need to undergo an examination of the body. It is necessary to pass an analysis to determine the presence or absence of diseases that are transmitted through the blood.

Donation has contraindications. Many people have a question, is it possible to donate blood with hypertension?

Previously, bloodletting was done at high blood pressure. A slight loss of blood contributed to the normalization of the condition.

Can blood donation make people feel better with hypertension? Does donating blood help lower blood pressure? You will find answers to your questions in this article.

In rare cases, a semi-conscious state is observed. The reason for this is a decrease in blood pressure, hemoglobin.

Despite the fact that blood pressure decreases with blood loss, a hypertensive person cannot become a donor. Donating blood is dangerous for his body. With an increase in blood pressure, any physical, psycho-emotional stress is harmful.

Blood loss is stress for hypertensive patients, which will cause a pressure surge. If the disease is in the acute stage, immediately after the blood sampling procedure, the pressure indicators can jump by 15-20 units. and more. Donation that is safe for healthy people can provoke the development of formidable complications in hypertensive patients - heart attack, stroke.


Can hypertensive patients donate blood?

Any blood loss is a trauma to the body (to one degree or another). People in good health will endure it without much consequence.

For the body of a sick person, this is a significant stress. In this regard, only people who do not have health problems and have passed a number of studies can become donors.

Hypertension is a serious disease in which the body constantly experiences discomfort. Any additional stress can cause a heart attack or stroke.

Hypertension patients


you can not donate blood, regardless of the stage of development of the pathology.

Some people are unaware of the disease. In this case, doctors will help identify hypertension. Before you donate blood, you will need to undergo a medical examination, including measurement of blood pressure.

The diagnosis of "hypertension" is made if the indicators are from 140/90. If blood pressure exceeds 145/90 or higher, donation is prohibited.

You can donate blood to hypertensive patients only for clinical trials. However, there are limitations here as well. Doctors do not recommend doing such tests more often than 2 times a week.

After all, even minimal intervention is bad for well-being. With hypertension, one must take care of health, high blood pressure and without other loads negatively affects the functions of internal organs.

Why do people with hypertension donate blood for analysis

Patients with hypertension will definitely need to donate blood for a general or biochemical analysis. The study allows you to determine the state of the patient's body, identify the main cause of the disease and select adequate therapy.


In hypertensive patients, they try to take capillary blood (from a finger). If it is necessary to take it from a vein, the patient's pressure is measured before and after the procedure. If the indicators significantly exceed the norm, blood sampling is not carried out.

When performing a general (clinical) blood test, hematocrit must be examined. This indicator reflects the ratio of the volume of erythrocytes to the total volume of blood. If the patient has had hypertension for a long time, hemoglobin rises in the blood, the number of red blood cells increases.

The disease can adversely affect the condition of the kidneys. A biochemical blood test for "renal tests" (creatinine, urea) reveals negative changes. It helps distinguish kidney disease from liver disease.

Indicators of the level of creatinine in the blood make it possible to assess the degree of purification of the body from metabolic products. The results of the analysis of clearance for urea (urea nitrogen) allows you to evaluate the work of the kidneys.

With the help of clinical studies, the amount of electrolytes (potassium and sodium) and the level of glucose in the blood plasma are determined. With a combination of hypertension and atherosclerosis, an analysis is made for lipid metabolism indicators (triglycerides, cholesterol levels).

If the doctor has an assumption that hypertension is secondary, the values ​​​​of aldosterone, catecholamines,


Who else can't donate blood?

A contraindication to donating blood and its components is not only arterial hypertension. People who have the following diseases are not allowed to donate:

  • AIDS;
  • Hepatitis;
  • Tuberculosis;
  • Congenital, acquired heart defects;
  • Blood diseases;
  • Myopia, blindness;
  • Lack of speech, hearing;
  • lung diseases;
  • Malignant neoplasms;
  • Ulcerative, pustular lesions of the gastrointestinal tract, etc.

Many of them are dangerous for both the donor and the recipient. Pathogens are transmitted through the blood, this will cause infection. To identify certain diseases, it is necessary to undergo a series of studies.

The following donors are also not allowed to donate blood:

  1. Pregnant and lactating women, within 1 year after childbirth and 1 month after the end of the breastfeeding period;
  2. Women during menstruation and within 5 days after their end;
  3. Persons who have had acute respiratory infections (within 1 month after recovery);
  4. Persons with skin rashes, mucosal lesions caused by allergies or other causes.

The use of narcotic drugs at least once also becomes a contraindication. You can not donate blood within 2 weeks after a course of antibiotic treatment, within 1 year after undergoing surgery.

You can not donate blood within 2 weeks after dental treatment with the extraction of teeth. Ignoring contraindications puts the health of the donor and the patient at risk.

Other diseases of the cardiovascular system

Along with hypertension, there are other diseases of the cardiovascular system in which donation is contraindicated. These include:

  • IHD (ischemic heart disease);
  • Atherosclerotic cardiosclerosis;
  • Atherosclerosis;
  • Obliterating endarteritis;
  • Heart disease;
  • Nonspecific aortoarteritis;
  • Thrombophlebitis.

Cardiac ischemia(IHD) is characterized by impaired blood supply to the myocardium due to lesions of the coronary arteries. Atherosclerotic cardiosclerosis is the development of scar connective tissue in the myocardium.

The cause of the pathological process is the defeat of the arteries leading to the heart. The disease is manifested by the development of IHD (ischemic heart disease).

vascular atherosclerosis is a chronic arterial disease. It is accompanied by the deposition in the lumen of the vessels of certain fractions of lipoproteins and cholesterol. Atherosclerosis develops due to a violation of the metabolism of proteins and lipids.

Obliterating endarteritis is a chronic vascular disease that predominantly affects the arteries of the legs. With the development of pathology, gradual obliteration (vasoconstriction) occurs. Complete closure of the lumen leads to the development of gangrene - necrosis of tissues that are deprived of blood supply.

Heart disease(congenital, acquired) is a change in the valves, walls, partitions or vessels of the myocardium. Pathology disrupts the normal blood flow in the small, large circles of blood circulation. Nonspecific aortoarteritis (Takayasu's disease) is manifested by chronic inflammation of the aorta and its main branches. The disease is accompanied by the following complications:

  • Stenosis (abnormal vasoconstriction);
  • Occlusion (violation of the patency of blood vessels);
  • Secondary ischemia (impaired circulation, anemia) of tissues and organs.

Thrombophlebitis called inflammation of the walls of the veins with the formation of blood clots (blood clots). Most often, the disease is localized in the lower extremities. The spread of thrombophlebitis to the deep vein system is fraught with the development of life-threatening complications. These include detachment, migration of a thrombus into the pulmonary arteries.

With these pathologies, donation is out of the question. Any load on the body of patients can lead to death. These people need medical attention and medication.

According to doctors, donation is good for health if there are no contraindications. The procedure promotes blood renewal, stimulating the work of hematopoietic organs.

All taken amount is replenished in the body for a certain time. Blood can be taken as separate components:

  • Cellular components (platelet-, erythrocyte-, leukocyte-containing);
  • Plasma;
  • Plasma constituents (cryosupernatant plasma, cryoprecipitate).

For the body, it will be a little more beneficial. After the procedure, the work of the hematopoietic organs will be directed to the production of only erythrocytes / leukocytes / platelets.

Regular renewal of blood cells is an excellent prevention of many diseases, including damage to myocardial tissues. According to medical statistics, pathologies of the heart system in donors develop 30% less frequently than in ordinary people. Clinical studies by foreign scientists confirm that donors have a reduced risk of developing atherosclerosis, coronary artery disease, and thrombophlebitis.

With regular blood donation, the body becomes resistant to possible blood loss that accompanies injuries and operations. Stimulation of the hematopoietic system contributes to the prolongation of youth.

Donating blood facilitates the work of the liver and spleen, which are involved in the process of removing dead red blood cells. Thus, donation is beneficial. It is necessary to mobilize internal resources, improve immunity.

Another positive side is that a person gets the opportunity to be examined free of charge. This allows you to identify AIDS, HIV, and other dangerous diseases. During a physical examination, other pathologies that do not manifest any symptoms can be detected.

Donors receive benefits. This is a 2-day leave from work - directly on the day of the procedure and on any other day. Honorary donors receive an allowance each month and are eligible for other benefits. This category includes citizens who donated blood 40 times, plasma - 60 times.

Men can donate blood no more than 4-5 r. per year, women - 3-4 p. The interval should be at least 2-3 months. A break is needed for the body to recover. Women are allowed to donate blood less frequently than men due to monthly blood loss during menstruation.

What to do before and after the procedure

Persons not younger than 18 years old and not older than 60 years old, with normal weight, which must be at least 50 kg, are allowed to donate. If a person takes any drugs, if possible, they should be abandoned 3-5 days before blood sampling.

It is especially important not to take aspirin, analgin. For 2 days, you should give up alcoholic beverages, for 2 hours - from cigarettes.

You need to donate blood after a good night's sleep. A person should be in good health and mood. On the day of the procedure, fried, spicy, dairy products, dishes should be excluded.

You can not eat nuts, eggs, chocolate, drink soda. In the morning you need to have a hearty breakfast. Porridge on the water, fruits (except citrus fruits and bananas) are suitable. Before you donate blood, you should drink sweet tea.

To help your body recover faster after the procedure, drink plenty of water. Sweet tea (weak) with cookies, bun, candy will be useful. You can buy a children's hematogen. After donating blood, it is important to give the body a rest: you need to lie down, but it is better to sleep.

Donating blood is a responsible task that only healthy people are allowed to perform. To become a donor, you will need to be tested for the absence of AIDS, HIV and other blood-borne diseases.

The procedure is also contraindicated for people with drug and alcohol addiction, diabetes, cancer, anemia and many other diseases.

What is dangerous

Donation, in its essence, is absolutely safe for a person. During the procedure, doctors use sterile disposable instruments, which are disposed of after collecting the required amount of blood. If a person is absolutely healthy, he slept well and ate well, then his health does not worsen.

A fainting state may occur due to a decrease in blood pressure and a decrease in hemoglobin levels, but this happens extremely rarely and doctors immediately take measures to eliminate the unpleasant consequences of donation.

But this applies to healthy people with normal blood pressure. As for hypertensive patients, donation, despite the seeming harmlessness, can lead to a heart attack and stroke. Donating blood is a small trauma for the body, so its reaction can be unpredictable.

Patients suffering from high blood pressure should give up any stress on the body. Therefore, most physical exercises, stress and other influences are contraindicated for them.

Donating blood is one of such loads, as it causes an exacerbation of the disease with a further deterioration of the disease.

Is it possible to donate blood with hypertension

And if you go a little the other way, is it possible to donate blood for hypertension without reporting your disease to the doctor? Hiding information about your health is fraught with an exacerbation of the disease.

In addition, many hypertensive patients are not even aware of their illness, explaining the deterioration of health by a change in the weather. Doctors at the blood transfusion station will be able to detect the disease.

Having measured blood pressure, and having studied the results of the tests, the specialist is most likely not to allow the patient to donate.

According to the Order of September 14, 2001 No. 364 “ON APPROVAL OF THE PROCEDURE FOR MEDICAL EXAMINATION OF A BLOOD DONOR AND ITS COMPONENTS”, hypertension of the 2nd and 3rd degree is a contraindication to blood donation. And, according to this order, hypertensive patients with a disease of the 1st degree are allowed to donate blood. But how does it work in practice?

Hypertension is divided into three degrees:

The diagnosis of "hypertension" itself is confirmed when blood pressure is above 140/90.

The reason for the refusal to donate is quite understandable - in the acute stage, the pressure will increase by at least 15-20 units. And this can happen immediately after blood donation, which is fraught with a stroke.

If, during the examination before donating blood, the doctor sees a reading of 145/90 or higher on the tonometer, then the donation will be refused.

Purpose of analysis

For the body of hypertension, donating any amount of blood is a kind of trauma, the reaction to which can be very unpredictable. For this reason, in patients with high blood pressure, it is not recommended to examine the analyzes no more than twice a week.

For these purposes, it is desirable to use capillary blood (from a finger), and not venous. Before and after the analysis, it is necessary to measure blood pressure and, in case of a significant increase, refuse to donate blood.

A blood test for hypertensive patients is prescribed for the purpose of:

  • identify the patient's condition;
  • clarify the cause of the disease;
  • get information about other indicators, such as glucose levels.

The analysis will allow a patient who wants to become a donor to obtain permission from the attending physician to donate blood. Perhaps this is with a stable remission, when blood pressure for several months did not exceed normal values.

In this case, the supervising specialist issues a permit for donation. But after donating blood, you need to control your pressure for several days.

If you want to become a donor, you need to carefully examine your body so that a useful procedure does not turn against you.

Other pathologies

Other contraindications to donation are:

  • mental illness;
  • hypotension;
  • HIV, AIDS, syphilis;
  • viral hepatitis and suspicion of it;
  • blood diseases;
  • tuberculosis;
  • heart disease;
  • lung and respiratory diseases;
  • diseases of the digestive system;
  • acquired heart disease.

Also, donors are not allowed to donate blood:

  • with a complete lack of speech and hearing (congenital and acquired pathologies);
  • after tooth extraction within 14 days;
  • within a year after childbirth and a month after the end of lactation;
  • pregnant and lactating mothers;
  • within 12 months after the surgery;
  • during menstruation and within 5 days after its completion;
  • having homosexual sexual relations;
  • using drugs even once;
  • within a month after suffering acute respiratory infections;
  • having allergic and other rashes on the skin and mucous membranes.
  • within 2 weeks of stopping antibiotics.

By ignoring the contraindications, the health of the donor and the patient, to whom the blood will be donated in the future, is at risk. Therefore, a thorough examination and testing is an important procedure that cannot be bypassed.

To become a donor, you will need:

  • be absolutely healthy, in good health and mood, after a good sleep;
  • eat well (low-carbohydrate food);
  • be of legal age, but not older than 60;
  • have a normal weight, not less than 50 kg;
  • be clean, tidy;
  • provide a fresh fluorography and the result of EGC;
  • have a passport with a local residence permit.

Within 3-5 days, if possible, refuse to take medication. This is especially true of analgin and aspirin. Two days before the procedure, you must give up alcohol, two hours before the procedure - smoking. Immediately before donating blood, you can drink sweet tea with a biscuit or a bun.

If a person is not aware of their diseases, but wants to become a donor, he will need to contact a therapist and undergo a complete examination of the body. Particular attention is paid to indicators of pressure, blood sugar, hemoglobin, and the absence of cardiac pathologies.

This procedure will be very useful: it is possible to diagnose diseases at the initial stage and prevent its development with a detrimental effect on the general condition of the body.

Why donate blood?

And finally, let's consider the positive aspects of donation for a healthy person who has no contraindications to donating blood. First of all, a person has the opportunity to regularly undergo a free examination for HIV, AIDS and other deadly diseases.

Preparing the body for serious injury is the second point. In the event of a serious blood loss and a donor, there are much more chances to survive and restore health than people who have never donated blood. The body learns to quickly replenish the lost blood supply and "remembers" the result achieved.

Regular blood renewal contributes to the prevention of many diseases of the body, including heart attack. According to statistics, donors suffer from heart diseases 30% less often than ordinary people. Therefore, blood donation is a useful procedure necessary for the mobilization of the body.

Men are allowed to donate blood 4-5 times a year, women 3-4 times a year. The interval between procedures should be at least 2-3 months required for the full recovery of the body. Women may be less likely to donate blood because they lose blood every month during menstruation.

Do not risk your own health with hypertension, because high blood pressure and without additional stress has an adverse effect on the work of many organs.

Hypertension and donation

Hypertension is a persistent increase in blood pressure above 140/90 mmHg. In this case, blood pressure is understood as the force with which blood acts on the walls of blood vessels that carry it. Under the action of increased pressure, these walls gradually collapse and become rough, calcium and cholesterol begin to settle on them. As a result of this, the capillaries become narrow and inelastic, they no longer allow enough blood to pass through them, which ultimately has a negative effect on vital organs: the heart, kidneys and brain.

Causes of hypertension

Among the factors provoking the development of hypertension include:

  • sedentary lifestyle;
  • diabetes;
  • mental trauma and stress;
  • hereditary predisposition;
  • salt abuse;
  • obesity, malnutrition;
  • high levels of cholesterol in the blood;
  • smoking and excessive alcohol consumption;
  • elderly and senile age;
  • malfunctions of the nervous and endocrine systems;
  • taking certain drugs (eg, appetite suppressants, contraceptives, certain anti-inflammatory drugs, glucocorticoids);
  • menopause in women;
  • previous kidney disease;
  • late toxicosis in pregnant women.

Donation as therapy

Donating blood temporarily lowers blood pressure. The stability of this effect has not been scientifically proven.

With a high degree of hypertension (2-3). after a short-term normalization of blood pressure, it is possible sharp rise. due to physiological mechanisms.

Thus, donation cannot be a treatment for hypertension.

To prescribe effective therapy, people with high blood pressure should consult their doctor.

Donation as a means of combating extra pounds?

Researchers from Germany have found that donation can help some obese people lose extra pounds. Donation also helps to reduce blood pressure in people with hypertension (high blood pressure), thereby reducing the risk of cardiovascular disease.

The study involved people with metabolic syndrome. This is the name for a combination of symptoms caused by heart disease, high blood sugar, high blood pressure and low levels of "good" cholesterol. Metabolic syndrome is associated with an increased risk of stroke, type 2 diabetes, and coronary heart disease. The main tool in the fight against these diseases is weight loss.

According to scientists from the Charité University Medical Center in Berlin, donation is acceptable for overweight people with high iron levels as a treatment for the above symptoms. However, until the study is completed, donation cannot be unconditionally recommended to all overweight people - this is the opinion of physicians from Harvard Medical School. They believe that more long-term observations are needed to argue that donation really makes life qualitatively better, and not just slightly reduces blood pressure.

Lowering blood pressure through blood donation

Scientists from Berlin have found high levels of iron in the blood in people with metabolic syndrome and diabetes. Another study confirmed that blood sampling lowers blood pressure in patients with resistant arterial hypertension (a condition in which blood pressure is above normal levels despite taking antihypertensive drugs).

Physicians from Berlin observed a group of 64 people with metabolic syndrome. At the beginning of the study, each participant donated about 300 ml of blood, and after four weeks another 250 to 500 ml. In this case, no additional special treatment was carried out. After six weeks, patients from the "donor" group were examined and it was found that each of the upper limit of pressure decreased by an average of 18 mm, that is, from 148.5 mm Hg to 130.5 mm Hg (group average). Recall that blood pressure is considered high if its "upper" value is more than 140, and moderately high if it is more than 130. In patients who were prescribed traditional drugs, the pressure decreased on average from 144.7 to 143.8 mm Hg.

Researchers believe that lowering blood pressure by as little as 10 mm can reduce the risk of myocardial infarction by 22% and stroke by 41%! It was also found that donation led to a reduction in heart rate and a decrease in blood glucose levels.

Donation as therapy?

Donating blood lowers blood pressure, but it has not yet been proven how stable such a decrease can be. There is also no exact data on which drugs the participants in the experiment took. It is possible that blood donation had such an impact precisely because the participants in the experiment had not previously undergone drug treatment. Lifestyle and habitual nutrition should be taken into account, these factors also affect the result of treatment of any disease.

Metabolic syndrome is not an infectious disease, so the blood donated by patients can be used for medical purposes. But if a person suffers from any other diseases (viral or infectious), his blood cannot be used for transfusions or other procedures.

Donating blood is already being used as a treatment for hemochromatosis, a condition in which a lot of iron builds up in the body.

So, donation helps reduce blood pressure in obese patients with metabolic syndrome, but it is not yet completely clear how such therapy can reduce the risk of heart attack or stroke.

Blood donation and hypertension

Benefits of donating blood in the absence of hypertension

Donating blood (Vlog#7)

Donating blood is a rather serious procedure and not everyone can become a donor. There are certain criteria that allow you to determine indications and contraindications for sampling. First of all, this concerns the presence of certain diseases, especially serious ones such as HIV infection, AIDS, the presence of cancerous tumors or diseases of the cardiovascular system. With such indications, blood sampling is strictly prohibited, because otherwise you can harm not only yourself, but also the patient.

A disease such as hypertension also belongs to the category of prohibition. It is characterized by a constant or intermittent increase in blood pressure. Accordingly, in the presence of this deviation, it is prohibited to donate blood, with the exception of acceptable pressure indicators and the line need for a donor. This will be discussed in this article.

Why is hypertension dangerous for blood donation?

Pressure surge always causes discomfort. This can be explained by the fact that the walls of the vessels of our body are under a certain pressure. This is the number with which blood presses on the walls of blood vessels. For example, when pressure is measured, two-digit indicators are obtained - this is 120/80. For an adult, this is the most optimal pressure at which you can feel good.

The first number shows systolic pressure, that is, the force with which blood presses on the walls of blood vessels after a heart contraction.

The second digit characterizes the pressure indicators in the intervals between heartbeats. The same can be said with certainty. That each person has a different pressure, but on average, in a calm state, it should not exceed 140/90.

There are also three stages of hypertension, which are respectively characterized by an increase in pressure. In the first stage, indicators within 160/100 can be considered the norm. The level can change during the rest of the patient or vice versa during physical exertion. As for the second stage, the indicators are slightly higher there, which in turn is characterized by other symptoms. These are numbers within 180/100, which can change during rest or exercise. With hypertension of the third stage, the highest rates can be counted. These are precisely those catastrophic figures in which a person must always keep his pressure under control. These are the limits of 200/115. The last stage is the most dangerous, since such hypertensive patients can not only donate blood, but also burden themselves with physical exertion or stress.

Almost the same symptoms are characteristic of all stages - headache, sleep disturbance, dizziness, pain in the heart, and severe vascular complications occur. Also for the third stage, a characteristic clinical picture in the form of damage to the heart and brain, which can lead to a heart attack. The kidneys, the fundus of the eye begin to suffer no less and, accordingly, complaints arise.

Can hypertensive patients donate blood?

The loss of any amount of blood for the body is some kind of trauma. Just a healthy person can tolerate it normally, and the patient will receive a significant blow. Therefore, only a healthy person who has undergone a number of relevant tests and some other examinations should categorically donate blood.

Hypertension is a fairly serious disease, so it can be said with accuracy that all hypertensive patients, regardless of stage, cannot donate blood. During the examination, you will need to take a general blood test, measure pressure and review the history of existing diseases. Therefore, the doctor will definitely not allow the patient for donation.

With hypertension, the body experiences constant discomfort, since high blood pressure still affects health. If you give an additional push at the same time, then a person may have a heart attack, which will significantly worsen well-being. Any doctor can tell you about this, especially for the elderly. In most cases, a person does not immediately notice an increase or decrease in pressure.

Often we sin on bad weather conditions or temperature changes. Although in fact you can measure the pressure and see that its indicators change and in some way make themselves felt. Much worse for those people who do not feel pressure drops. This is very dangerous, because even at the highest pressure, the state of health will be satisfactory and it will be possible to continue to engage in either physical activity or something else that is so dangerous in such situations. Therefore, you can donate blood during pressure surges only for tests..

But do not forget that the analysis has its limitations. With hypertension, it is not recommended to donate blood for tests more than twice a week. Even the most minimal intervention can adversely affect the state of health with hypertension.

Why take a blood test for hypertension

Such an analysis is simply indispensable for hypertensive patients. After all, with the help of it, doctors manage to determine the condition, the disease, its main cause and the state of the organs that are under a lot of pressure. In this case, blood is taken from a vein on an empty stomach, as with all other tests. The presence of the necessary indicators is determined. It is also a great opportunity to choose the right treatment for the patient.

If the test results are not very high and the pressure is also within the normal range for the first stage of hypertension, then in exceptional cases it is allowed to donate blood as a donor. In such situations, the donor is taken under strict control and pressure drops are monitored for the entire time of the sampling itself.

If the first symptoms of an increase or deterioration in the donor's well-being appear, the procedure is stopped. Such cases may occur when there is an urgent need for donation. For example, after severe blood loss during surgery or childbirth in a woman. Such emergencies are more than dangerous, and it is not always possible to find a suitable donor. Therefore, they take blood under strict control.

Who else can't donate blood?

This question torments almost every person who wants to help the sick and become a donor for him. For example, come once a month and leave blood for those who really need it. But, despite this, medicine has its own rules and limitations.

You can ignore some of the rules of blood sampling, but in no case by restrictions on donation. Categorically restricted are people who have: AIDS, syphilis, HIV infection, tuberculosis, viral hepatitis, complete lack of hearing and speech, hypertension, congenital or acquired heart disease, malignant tumors, endocarditis, total blindness, various lung diseases, stomach ulcers , pustular diseases of the stomach, myopia, psoriasis, trachoma and many others. Such diseases pose a danger not only to the donor, but also to the patient himself.

Together with the blood, the disease can pass to another, because all the smallest inflammatory bodies are present in the blood. In order to determine the presence of certain diseases, before taking blood, the donor undergoes a number of certain procedures for verification. And only after that it is allowed to be a donor.

Other diseases of the cardiovascular system

There are still some problems of the heart and its entire system that do not allow donating blood for donation. Along with hypertension, they also play a significant role, as they are quite serious and dangerous to health. You may not know about the presence of some of them, but it is better to double-check before taking blood so as not to harm your body even more. These are atherosclerosis, ischemic disease, defects and inflammation of the heart, and some vascular diseases. In such cases, death can often occur, so there can be no talk of donation. Such a patient himself needs help and taking many medications.

In medicine, there are quite a few cases when patients, not knowing their main diagnosis, decide to donate. This can turn into a tragic outcome for the patient. A long time ago, medical scientist Davydovsky called such diseases uncharacteristic of the environment, since with such symptoms a person cannot adequately adapt to progressive urbanization. It is urbanization that is associated with a person's lifestyle and is influenced by stressful situations. The ecology and some features of civilization also have a significant impact on health and well-being.

Benefits of donating blood in the absence of hypertension

You can talk a lot about the fact that the development of certain diseases is influenced by the image of a person or ecology. But the main focus is the individual disposition of a person. But, despite the many such factors, doctors argue that it is possible and necessary to donate blood, in the absence of such diseases.

During blood donation, the body renews itself. That is, all the taken amount is replenished for a certain time and stimulates the work of hematopoietic cells. We can say that it is even very useful, because it is necessary to rejuvenate not only the skin, but also the cells of our body. Thus, the body receives an impetus for more active work to compensate for the lost amount of plasma. Since blood can be donated not only in full, but also in its individual components, this is a little better for the body. The active work of hematopoietic cells in this case is directed directly to the production of red blood cells, white blood cells or platelets. It is these components that can be donated separately from plasma.

Women can donate once every two months, and men once a month. Thus, you help not only the sick patient, but also yourself. The main thing immediately after the delivery is to help the body work. You can drink sweet tea with chocolate or something else tasty. Since glucose is no less important in hematopoiesis, its amount should be sufficient for the active work of the bone marrow. Rest a little after the procedure and you can be sure that the procedure was successful, and your blood will benefit those who need it.
