About blood transfusion: the dangers of donation and how to avoid infection. Is it useful to donate blood? The benefits and harms of donation Is donation beneficial for a woman?

Donation is practiced in different countries. In Russia, the volunteer movement is gaining momentum. He has many supporters and opponents. Proponents argue that if you donate blood at a certain frequency, this will extend your life by several years. And opponents argue that donating blood is a huge stress for the body, and even during the blood collection procedure they can introduce an infection, almost HIV. Let's try to figure out whether donating blood is useful or harmful.

Who can donate blood to?

Blood donation is allowed to men and women from 18 to 60 years of age who have permanent registration in the Russian Federation. There are certain contraindications that prevent you from donating blood:

• HIV, hepatitis or other infection;
• , lactation;
• Diabetes;
• Weight less than 50 kg;
• Anemia;
• 6 - month postoperative period;
• Low pressure.

Before donating blood, you must always be examined by a doctor. And only he decides who is allowed to donate blood and who is not. In any case, if you feel unwell, you should refuse to donate blood until your condition improves.

How to prepare for donating blood?

Donating blood is a simple process on the one hand, but if the preparation and behavior are improper, the donor may feel unwell or the quality of the blood will decrease. After all, the main task of a donor is to give good blood that will help another person. There is no way to make money from this; the financial compensation is very modest. And most donors act from highly moral motives. A couple of days before the procedure, you should absolutely avoid alcohol and medications. It is advisable not to do so the day before.

It is not recommended to donate blood while on a strict diet of kefir and apples. This is especially true for women. Because with insufficient nutrition, when the body lacks certain nutrients and vitamins, one feels weak, tired, and weak. And when blood is taken, the condition may worsen to the point of loss of consciousness. But a bias in the opposite direction is also not necessary; you should not overeat fast food, salty, fatty foods the day before. It is better to focus on fish, chicken, vegetables, fruits, cottage cheese, kefir, and cereals. On the eve of the procedure, you need to get a good night's sleep so that on the day of the procedure you feel rested and full of energy. Psychological preparation is also important. Calm, calm and nothing more. If a person is terrified of the sight of blood or injections, then donation is most likely not for him. Donating blood is a matter of personal choice.

Procedure for donating blood

The blood is drawn by a professional staff member with medical training using disposable sterile instruments. Therefore, there is practically no risk of getting an infection after the procedure.

During this procedure, 450 ml of blood is usually collected. This is about 10% of all the blood that is in the human body. Therefore, there is no threat to life or health. Women are recommended to donate blood no more than 4 times a year, and men -5. This can be explained by concern for the health of the donor. Otherwise, hemoglobin in the blood may decrease, or the body will not be able to fully recover. As a result, for example, immunity may decrease and sugar levels will increase. After the procedure, you need to drink warm tea with sugar and eat well. On this day you may feel a little weak and tired. Therefore, on this day you need to eat often, but little by little, not work, at least physically, and go to bed early.

The effect of donating blood on the body

Taking a small volume of blood has a stimulating effect on the entire body. Previously, they even treated with bloodletting high blood pressure. Now there are more effective means normalize blood pressure. But the positive effect of donating blood cannot be denied. In particular, the following aspects can be noted:

Benefits for Donors

Donors are entitled to receive specific benefits. There are ordinary and honorary donors. Honorary donors include people who were able to donate blood at least 40 times or plasma at least 60 times. Honorary donor status guarantees more benefits. In any case, a person who donates blood can count on the following benefits:

1. Two days off, which are paid. The first is given on the day of the procedure, the second on any day at the request of the donor. You can even join your vacation this day;
2. Meals at public expense on the day of the procedure or compensation in cash;
3. In the case of donating blood free of charge in the amount of double the norm for one year, the donor has the right to receive a preferential voucher for sanitary and resort treatment at the place of work or study in the first place.

In addition to the above, honorary donors are entitled to:

1. Out of turn medical care in public medical institutions;
2. Receiving financial rewards every year;
3. Receiving vacation at the desired time every year;
4. The right to receive a preferential voucher for sanitary and resort treatment in the first place.

Thus, we received an answer to the question: is it useful to donate blood? We learned about the positive impact of the blood donation procedure on the human body, but subject to proper preparation, as well as following the normal regime after the procedure. In addition, you should understand that by donating blood on a regular basis, you will have to carefully monitor your health. And coupled with the positive effects that donating blood has on the entire body, good health, youth and longevity are guaranteed.

Video about donation

In this video you will learn why to donate blood:

Today, donation of blood and its components is widespread. This is one way to help people who have suffered significant blood loss as a result of complications from surgery or accidents. There are a lot of such people. As more and more volunteers answer the call to become blood donors, the question arises: is it beneficial for men and women to donate blood? What changes occur in the body if you donate some of your own blood to other people several times a year? Let's figure it out.

Regular checking for infections

If you often provide yourself as a blood donor, then before each collection of material your blood is checked for the presence of infections. This allows the donor to constantly monitor his own health, and if abnormalities are detected, begin treatment immediately. Most people do not have this opportunity because they rarely go to the hospital for tests, so they learn about their ailments only when the disease manifests itself on a physical level and progresses. This is one of the positive aspects that shows why being a donor is useful. But that’s not all; by donating blood, a person literally heals his body.

What benefits does donation bring to the health of the body?

It is believed that bloodletting has a healing effect if performed in small volumes. When a volunteer donates his blood to a patient, he gives away about 450 grams of life-saving fluid. A loss of such volume is insignificant and cannot harm the donor in any way.

Donating blood allows you to accustom your body to small blood losses. If some situation arises, for example, an accident or a serious operation, the body of a person who has repeatedly donated blood will find itself in a familiar situation. It activates processes that allow you to quickly replenish the lost volume of red blood cells.

Small blood losses contribute to the rejuvenation of the body, its self-cleaning and cell renewal. This process gives the liver the opportunity to rest a little, which usually processes used red blood cells. The bone marrow, on the other hand, works hard to produce new blood cells to replace what is lost. Moderate blood loss also has a good effect on the cardiovascular system.

Donating blood is a little stress for the donor’s body, thanks to which its protective functions are activated. The immune system comes into “combat readiness”, thanks to which donors are less likely to suffer from colds and viral diseases.

According to American doctors, people who donate blood regularly are less susceptible to developing atherosclerosis, coronary disease hearts, as their veins are constantly cleared of excess bad cholesterol. According to several studies, donation prolongs life by at least 5 years.

Donating blood is also useful from a psychological point of view. Helping others gives you joy and satisfaction, and every person needs such emotions. They are known to promote good health. Well, for the patient who needs your blood, the benefit is obvious - you will save his life.

Rules for donating blood

If you want to participate in the donation program, you should familiarize yourself with the rules, recommendations and restrictions in this regard. Anyone over the age of 18 who does not have infectious diseases can become a donor. The upper age limit was recently removed, so even people over 60 years of age, provided they are in good health, can become blood or plasma donors. The volunteer’s weight should not be less than 50 kg, however, persons in this weight category can become donors in the absence of contraindications. No more than 300 ml of blood is taken from such people.

Men can donate blood no more than 5 times a year, while women are allowed to do this 4 times within 12 months. Women should not donate blood more often. This restriction makes sense for them because their bodies lose a small amount of blood each month during menstruation. The interval between fences should be at least two months. During this time, the body of a healthy person is completely restored.

Preparation for blood collection or its fractions includes a full healthy diet(refusal of fatty foods, smoked, fried) for 2-3 days before the procedure. During this period you should not take any medical supplies and also abstain from alcohol. Immediately before the procedure, the donor is examined and tested for various infections. If everything is in order, the person is allowed to undergo this procedure and is allowed to become a donor. After the procedure, the donor is advised to rest. You cannot engage in heavy physical labor or travel long distances. During the recovery period, it is desirable to include in the diet beef liver, pomegranate, cranberry.

Donating blood is not only a useful, but an honorable procedure that allows you to do good unselfishly to other people, giving them a piece of yourself so that they can live. For such actions, the state rewards donors who have undergone this procedure more than 40 times in their lives with benefits and annual payments, provides them with additional time off and vouchers to a sanatorium.

The most common question in medicine is whether it is useful to donate blood. Today, donation is widespread throughout the world, and in some countries it is one of the components of a healthy lifestyle, along with proper nutrition and playing sports.

Anyone can express a desire to become a donor. To do this, he needs to come to any blood transfusion station, which are available in almost any locality, and fill out a donor questionnaire, where you describe in detail your state of health and previous diseases. Also, one of the important points for passing the donor commission is medical examination and taking a blood test, based on the results of which the candidate will be allowed to donate. Specialists conducting a medical examination of the candidate reserve the right to refuse admission to donation if any minor violations are detected without specific reasons and explanations as to why the refusal was given.

If you have successfully passed the commission and become a donor, laboratory specialists will explain to you the rules, procedures, and benefits of donating material without harm to your body. Following these rules will allow you to regularly submit material and participate in saving the lives of people around the world, benefiting yourself.

There are two types of submitted material:

1. Whole blood donation occurs by collecting from 200 ml to 450 ml of venous blood. The amount of sampling material is determined by the time you donate blood, for example, if this is your first donation, then the material will be collected in sizes from 150 ml to 250 ml. For subsequent donations, a one-time norm is considered to be a blood donation of up to 450 ml;
2. Donation of plasma and its components. People susceptible to thrombocytosis need more platelets when their body does not produce enough of them. In this case, they resort to using donor material. For the donor's body, the collection of material is less noticeable than the collection of whole material. Since the required component is mechanically isolated from the specified amount, and unused blood is returned back to the donor.

The donor can be confident in the sterility of the manipulations being carried out, since transfusion stations pay special attention to this Special attention. As a result of regular donation of matter, circulation and cleansing of the circulatory system occurs, which will have a beneficial effect on the donor’s body.

Requirements and contraindications

There cannot be certain strict requirements in the selection of candidates. The main thing is that the applicant has no infectious and viral diseases transmitted by blood.

An applicant for donation must meet the following parameters:

• the candidate has reached 18 years of age, but not more than 60 years of age;
• body weight must be at least 50 kg.

If these two requirements cannot be met, specialists will not allow the unsuitable candidate to even pass the medical commission. Also, during the examination, the psychological state of the applicant is studied in detail; if mental abnormalities are detected, doctors will refuse permission to donate.

Contraindications for donating blood to both men and women are individual characteristics of the body, for example, anemia, leukemia, etc.

Blood donation is also limited in the following situations:

• Material collection from men can occur no more than once every two months.
• Women are recommended to donate once every three months. It is necessary to pay attention to the menstrual period, during which female donors are prohibited from donating 5 days before the onset of menstruation and 5 days after their end. It is also prohibited to donate blood to pregnant women, and during breastfeeding, you can return to donation after pregnancy one year after finishing breastfeeding.
• After suffering from an illness such as ARVI or ARI, access to donation will be allowed a month after final recovery.

These requirements are mandatory and must be followed by every donor. The use of such radical measures is necessary to maintain the safety of both the donor and the recipient.

Why you shouldn't donate blood often

The circulatory system is replenished and renewed due to the content of substances such as platelets, leukocytes, and erythrocytes. Nature provides for the renewal of blood and its constant circulation in the human body; the body contains a certain amount of it.

The blood norm for a person is up to 6 liters, with this indicator maintaining the normal functioning of the entire organ system. Each cell of the inner world is supplied with oxygen and can perform all its functions fully.

Frequent blood sampling from a donor can affect his health, since the level of vital material will be reduced, therefore, the body will have limited nutrition and may be in a state of oxygen starvation, which can lead to the death of organ cells. Such damage can be compared to severe blood loss or hemorrhage, so it is very important to comply with the permitted number of donations per year.

Men can donate blood no more than 6 times a year, women no more than 4 times. These indicators are calculated for donating whole blood; you can donate the material for components every two to three weeks, subject to all requirements and contraindications. The number of times to collect material for components should not exceed 12 times a year.

Benefits of donation

By complying with all the requirements for conducting and preparing the donation of material, without exceeding the recommended amount of blood sampling, the body does not experience discomfort and does not suffer harm. In addition, by donating material, your body can be regularly renewed, and therefore the circulatory system is cleansed, this is a definite benefit. For many diseases or allergic reactions Doctors prescribe a patient's blood transfusion without the use of donor material. Such measures help renew blood components, and often get rid of many unwanted infections and reactions.

Also, with regular donation of material, the donor’s body, in the event of a threat, will more easily accept donor blood. This process is due regular replenishment and restoration of the circulatory system. The benefits of transfusion and donation are obvious. By becoming a donor, you help not only yourself and your body, but also thousands of other people in need of transfusions.

The main thing is to approach this issue correctly and with special responsibility. Having become a donor, you must understand that you should forget about bad habits; donation in its essence represents healthy image life, in which it is important to observe all the details from proper nutrition to sleep and rest.

What is blood donation?

As we know from history, bloodletting used to be a well-known medical technique for treating many diseases. To be honest, back then it was used both appropriately and inappropriately. But at the end of the 11th and beginning of the 20th centuries, they began to increasingly move away from this technique. But the practice of transfusion was begun, usually it was carried out in cases where the patient had severe blood loss. In this practice, the discovery of Rh factors and other properties of blood played a great role.

Moreover, since that time, doctors have argued that this procedure useful for the donor as well. But the last statement is true only with a number of reservations.

Firstly, only donating blood at a certain time interval is useful. Secondly, the health status of the person giving the exam is very important. Thirdly, it is very important to carry out the entire range of preparatory measures to allow blood sampling from maximum benefit for a person and without the threat of harm to his health.

Separately, the importance of these rules regarding female representatives should be emphasized. Girls are allowed to donate blood somewhat less often than men. After all, every month during menstruation they already experience blood loss.

Pre-delivery stage

First, you need to go through certain testing procedures. This is necessary for several purposes at once. On the one hand, to determine the health status of the donor. Make sure that it is permissible for him to donate blood without harm to himself. On the other hand, make sure that the donated blood will not carry any diseases.

A very important point is checking the group and Rh factor. Usually done general analysis in order to identify the possible content of viral cells. In particular, hepatitis B and C, HIV infection, syphilis, etc.

It should be emphasized that age does not play a role in terms of blood transfusion. That is blood young man You can transfuse it to an elderly person, and an elderly person to a child. This is possible because human plasma is ageless.

In addition, you should definitely undergo a general examination by a doctor to determine general condition health. It happens that taking blood is contraindicated due to certain indicators. Often the group of such people includes those who have undergone certain types of operations, have tattoos or piercings.

Among other requirements that the donor must meet is normal weight. It must be at least 50 kg.

Separately, you should consider the issue of donating blood to nursing mothers and pregnant women. In some cases, taking blood from them is prohibited. But in some cases, on the contrary, it is very useful, provided that the volume of blood donated is small.

The benefits and harms of donation

Provided that the above conditions are met and there are no contraindications, donation is a very useful procedure, which has been proven by many years of practice.

In this case there are usually no disadvantages.

But exceeding the permissible donation volumes, donating blood too frequently, which does not allow the normal amount to be fully restored, and donating blood to a person suffering from certain diseases can lead to a number of unpleasant, and even hazardous to health, consequences.

interesting" side effect“donation is that professional donors who donate blood regularly begin to feel the desire to donate it constantly. And if they don’t pass it on time, this causes psychological and physiological discomfort for a number of them.

The most useful moments of donating blood traditionally include:

• it stimulates the normalization of blood circulation and restoration of the body;
• acts as one of the measures for disease prevention cardiovascular systems s;
• the body begins to become more active, development is stimulated immune system;
• the liver is unloaded independently, and the work of the spleen is also prevented;
• It has been noticed that after periodic blood donation, the body begins to better resist severe bleeding.

In addition, all these positive aspects are achieved without taking medications, which are usually harmful to health to some extent.

But still, despite the advantages, it is important to pay attention to the ban on excessively frequent blood donation. So, men should not take it more than 5 times a year. Women – no more than 4 times.

You should not give yourself serious physical activity, at least two days before blood sampling. You will also need to limit your intake of fried and fatty foods, eggs and especially alcohol.

It is a good idea to donate blood after a balanced diet. You should not lead an active lifestyle for several days after the procedure. It is better to rest, but not to go on long journeys.

Other points of surrender

Donation is very honorable and important these days: every day someone needs a blood transfusion. Therefore, every donor potentially saves someone’s life or maintains their health.

As noted above, it is dangerous to be a donor only if the rules are not followed. In addition, it is important that blood donation is carried out only in specially equipped and designated areas specifically for this purpose. Such places, like all equipment, must be sterile. And the procedure itself must be carried out by qualified medical professionals.

You should not agree to have blood drawn without a preliminary examination and all the necessary tests. In addition, another important point should be emphasized. Donating blood is free. In other words, do not believe if they convince you that you must also pay for this procedure. Such a statement could be either a bad joke or an attempt by scammers to take your money.

In addition, donating blood provides some material benefits. So, for recovery, a person should be given additional days off. Material rewards are also provided. But with the latter, not everything is as good as we would like.

We also note that the doctor’s responsibilities include warning the donor about the need for a balanced diet, the rehabilitation period and other important points.

The blood donation process itself takes about half an hour. Sometimes it is necessary direct transfusion, which may last a little longer. In addition, there are cases when a transfusion of blood is not required, but only of certain of its components - usually leukocytes, necessary to protect the body from disease. In such cases, transfusion is carried out from the donor to the patient through a special device that filters out leukocytes and transfuses them into the patient’s blood. The machine returns the rest of the donor's blood plasma back to him.

There are special lists of donors. Having become one of them, you should be prepared for the fact that in case of emergency, this or that hospital may turn to you for help in order to save someone’s life.

Why is it useful to be a donor?

Many doctors claim that the benefits of donation for the body are irrefutable. In many civilized countries, this has become an integral attribute of a healthy lifestyle, akin to proper nutrition or exercise. Our article will tell you what you need to know about donation in order to understand its significance.

Benefits of donation

Medical experts believe that regular donation of blood provides a person with the prevention of diseases of the immune system. In this case, we are talking about cumulative diseases caused by metabolic disorders, which include gout, atherosclerosis, as well as dysfunction of the pancreas, stomach and liver. Researchers have also proven that systematically donating blood for transfusion to patients can reduce the likelihood of cardiovascular pathologies, since excess blood and its components gradually put more strain on the blood vessels and heart.

It sounds strange, but donation can be a good prevention of sudden bleeding. The body, accustomed to actively producing new blood, will be able to restore strength faster. After all, one of the reasons for women’s longer life expectancy is systematic blood loss in the form of menstruation.

It is worth taking into account that the donor in most cases experiences a colossal surge of positive emotions. In addition, another significant bonus is that diagnostics of the body before donating blood are carried out absolutely free.

How should a donor behave after donating blood?

You need to get proper rest and eat. It is no coincidence that donors are given official time off from work on the day of blood donation. It takes a couple of weeks at most for the human body to restore the full volume and composition of the blood.

How often are you allowed to donate blood?

A man can donate his blood to good causes up to five times a year, and a woman up to four times a year.

Who is allowed to be a donor

A healthy person, regardless of gender, age within a year, can become a donor. The donor must weigh fifty kilograms or more, and constant temperature The donor's body temperature should be up to 37 degrees Celsius. Acceptable values ​​of systolic pressure are within units, and diastolic pressure is within units. Pulse rate – beats per minute.

People are allowed to donate blood strictly after consultation with a therapist and transfusiologist, as well as an examination of the body.

List of contraindications for donation

There are absolute and temporary contraindications to the admission of a person to the list of donors, depending on the disease or other reason.

Absolute contraindications

AIDS, HIV, syphilis, viral hepatitis, tuberculosis, brucellosis, typhus, leprosy, echinococcosis, oncology, diseases of the circulatory, nervous and cardiovascular systems, emphysema, bronchial asthma, obstructive bronchitis, chronic diseases liver, calculous cholecystitis, liver cirrhosis, gastric and duodenal ulcers, urolithiasis, diffuse and focal kidney damage, pathologies endocrine system with severe functional and metabolic disorders, high myopia (from 6 D), complete blindness, acute and chronic severe purulent-inflammatory diseases of the ENT organs, psoriasis, erythroderma, eczema, pyoderma, sycosis, lupus erythematosus, blistering dermatoses, fungal infections internal organs and skin, acute and chronic osteomyelitis, pustular skin diseases, surgical interventions in case of organ resection or, conversely, transplantation (replacement of affected organs and tissues).

Temporary contraindications

Transfusions of blood or its components, surgical interventions, including abortion, tattooing or acupuncture of the donor, stay on business trips for more than 2 months in a row, stay in malaria-endemic countries in subtropical and tropical climates for more than 3 months, a history of malaria in the absence symptoms and negative results immunological tests, close contact with patients with hepatitis, typhoid fever after recent recovery, influenza, ARVI, tonsillitis, tooth extraction, vegetative-vascular dystonia, acute or chronic inflammatory processes in a state of exacerbation, menstruation, pregnancy and lactation, allergies in a state of exacerbation, recently made vaccinations, appointment medicines or products containing alcohol. For each of these and others possible reasons temporary people are not allowed to donate. More detailed information can be found by making an appointment with a hematologist.

Harm of donation

Donation is undoubtedly a necessary and noble cause. But any intervention in the human body (especially at this level) is far from being as simple as it seems to many. Be that as it may, each type of donation (blood, skin, internal organs, etc.) poses certain risks for both the donor and the recipient (recipient).

Risk for the recipient. Many people, as well as their relatives, worry that when taking blood they may be infected with some kind of disease. In fact, the recipient of the blood is more likely to become infected. After all, to draw blood, you should only use disposable instruments and consumables. But the recipient receives someone's blood. For example, during a difficult birth, you cannot use donor blood from a person who drank alcohol or smoked cigarettes less than 2 days before donating it. Otherwise, the newborn runs the risk of poisoning the body. People with weakened immune systems are at greatest risk of contracting something from a blood transfusion.

Risk for the donor. It should be noted once again that if the rules for donating blood are followed, the negative consequences for the health of the donor are minimal.

Summarizing all that has been said, it is clear that the benefits of blood donation are obvious, and the risks of contracting infectious and other diseases are reduced to zero.

The benefits and harms of donating blood: 12 misconceptions about donation

Donor blood transfusion has a history of almost a century. Despite the fact that this procedure is quite familiar to many people, the process of donating blood is still surrounded by numerous myths. Today we set out to debunk the most common of them.

Donating blood is harmful to health

The amount of blood circulating in the body of an adult is on average 4000 ml. It has been proven that the periodic loss of 12% of this volume not only does not have a negative effect on health, but also works as a kind of training that activates hematopoiesis and stimulates resistance to stress.

The volume of a one-time donation of donor blood does not exceed 500 ml (of which about 40 ml is taken for the purpose of testing). The body quickly replaces blood loss without any negative consequences.

The blood donation procedure is painful and tiring

Modern donor centers are equipped with everything necessary to make the person donating blood feel comfortable. The donor's discomfort is reduced to instant pain at the moment of needle insertion. The further procedure is absolutely painless.

Donating whole blood takes about a quarter of an hour. After its completion, the donor may experience slight fatigue, so on the day of the procedure it is not recommended to engage in heavy physical labor or go on a long trip. Donating blood components (plasma, platelets or red blood cells) can take up to one and a half hours.

There is a risk of donor infection

Many people believe that the donor runs the risk of receiving one of dangerous infections blood-borne diseases (for example, hepatitis C virus or HIV). Currently, this is absolutely excluded: only disposable instruments and devices are used for blood collection, which are unpacked in the presence of the donor, and after the procedure they are immediately disposed of.

The need for donor blood is low

Patients undergoing complex procedures require blood transfusions. surgical operations, women in labor with complicated childbirth, people with severe injuries or burns. Donor blood and its components are used in the treatment of leukemia and other oncological diseases. There are artificial blood and plasma substitutes, but their use has a number of contraindications, as they sometimes lead to negative side effects.

In order to fully provide the healthcare system with the required amount of blood, donors must be one person out of 1000. In some European countries this ratio has been achieved, but in Russia this indicator is still well below normal.

According to statistics, every third person on our planet needs a blood or plasma transfusion at least once in their life. At the same time, the blood of absolutely all groups is in demand, and not just rare ones, as is sometimes believed.

Anyone can become a donor

This is far from true. In Russia you cannot become a donor:

• under the age of 18 or over 60 years of age;
• having a body weight of less than 50 kg;
• being infected with hepatitis, human immunodeficiency virus or tuberculosis;
• having any blood disorders or diseases of the blood (blood-forming organs);
• suffering from cancer.

Temporary restrictions on blood donation apply:

• for pregnant women (blood will be accepted no earlier than one year after birth);
• for nursing mothers (they can become donors three months after the end of lactation);
• for women during menstruation (blood donation is allowed at least a week before the start or a week after the end);
• for people who had the flu or acute respiratory viral infection less than a month ago;
• for patients who have undergone dental surgery (at least ten days must pass);
• for people who were treated with acupuncture less than a year ago, or who had a tattoo (piercing) of any part of the body;
• for patients who have recently undergone vaccination (the period elapsed before donating blood depends on the type of vaccine and ranges from ten days to a year).

In addition, an exemption from donation can be obtained if tests on the day of the procedure show the presence of an inflammatory process or traces of alcohol in the body, the body temperature is elevated, or if there are serious deviations from normal indicators blood pressure. Men can donate blood no more than five times a year, and women - four times a year.

Donating blood for transfusion requires a responsible attitude. Two days before the procedure, the donor must give up alcoholic beverages. You should refrain from smoking for at least an hour before blood collection. Three days before the procedure, you must stop taking medications that reduce blood clotting (including aspirin and painkillers).

The donor should eat high-calorie foods before and after the procedure

The day before donating blood, you should not eat fatty, dairy, meat foods, eggs, smoked foods, chocolate, bananas, canned food and fast food.

It is important that the future donor does not make mistakes that could negatively affect his health. It is better to donate blood in the first half of the day. Before the procedure, you need to get a good night's sleep, have breakfast, preferring porridge or pastries and sweet tea. After donating blood, you should eat a balanced diet (at least five times a day if possible) and remember to drink plenty of fluids to replace blood loss.

Donating blood may cause weight gain

Donation itself (including regular donation) does not affect body weight in any way. There is a risk of gaining weight for those people who, having misunderstood the recommendations for nutrition, begin to intensively consume high-calorie foods to donate blood and cannot stop in time.

Donation is bad for your appearance

Some women are hesitant to donate blood, believing that this will negatively affect their complexion and skin elasticity. In fact, regular donation activates the work of the hematopoietic organs, causes the blood to renew itself faster, and has a beneficial effect on the functioning of the immune, cardiovascular and digestive systems.

Donors, as a rule, do not have problems with the tone and color of their skin. They are cheerful, fit, active and have a positive attitude.

Regular donation is addictive

In this case, we can talk about addiction only in the sense of increased resistance of the body to various stresses, diseases and negative influences of the external environment. Thus, regular blood donation teaches the body to quickly replenish blood loss, which can play a positive role in the event of an injury or illness from which no one is immune.

It has been clinically proven that donation reduces the risk of developing cardiovascular pathologies. Some men note that regular blood donation has a positive effect on potency.

For a successful blood transfusion, the donor and recipient must be of the same nationality

The statement has nothing to do with reality. The compatibility of the donor and the recipient (the person to whom the blood is transfused) depends solely on the composition of the blood, that is, the presence or absence of certain proteins in it. For transfusion, the compatibility of blood groups (AB0 system) and Rh factor is important. These indicators are distributed almost equally among different races and ethnic groups.

With a suitable protein composition, donor blood can be transfused to the recipient, regardless of gender, age or nationality.

The personal qualities of the donor can be transferred to the recipient

Prejudice has very ancient roots. It is consonant with the ideas of primitive people that by eating the organs of an enemy, one can acquire his strength, courage, intelligence and other wonderful qualities. A similar misconception existed in the Middle Ages, when blood was considered to carry part of the human soul.

In fact, a blood transfusion does not add any of the donor's personal qualities or abilities to the recipient. It can only aggravate health problems if an unscrupulous donor allowed himself to donate blood without giving up bad habits. The reason here is not the transmission of information encrypted in the blood, but the fact that breakdown products of nicotine, alcohol and other toxins that can cause harm to health can enter the recipient’s bloodstream. That is why the donor must be very responsible, and the medical staff must be attentive.

The Church considers donation unacceptable

Donation is approved by major faiths as an act of self-sacrifice and a cause aimed at saving human life. Adherents of some sects who refuse blood transfusions and do not allow their children to undergo the procedure are making a huge mistake, which often leads to death. Many authoritative representatives of Orthodox Christians consider this a direct violation of the commandment “thou shalt not kill.”

Is it dangerous to be a donor?

A new study has confirmed that blood donation is not harmful to health and does not cause cancer. "You don't have to worry that if you donate blood frequently, you'll get cancer," said study leader Gustave Etgarn from Stockholm. “In fact, donating blood can even be beneficial.” A new study has confirmed that blood donation is not harmful to health and does not cause cancer. "You don't have to worry that if you donate blood frequently, you'll get cancer," said study leader Gustave Etgarn from Stockholm. “In fact, donating blood can even be beneficial.”

“People who donate blood frequently are less likely to develop cancer than those who don’t,” Dr. Etgarn and colleagues wrote in the Journal of the National Cancer Institute.

However, since donors tend to have better overall health, frequent blood donations may mask emerging diseases. The scientist also said in his interview that there are certain prerequisites that donating blood can affect health.

Loss of blood from the body leads to activation of the bone marrow, which stimulates the active production of blood cells. Increased cell division, so-called “mitotic stress,” may increase the likelihood of malignant disease of the hematopoietic system. Blood loss causes immune changes in the donor's body, and this can cause cancer.

The positive side of donation is the fact that iron reserves in the body are reduced. Excess iron can cause various diseases, so people who donate blood frequently can improve their health by reducing these excess supplies.

Dr. Etgarn and his colleagues decided to find out how donation actually affects the human body. They examined archival data from Swedish and Danish blood banks, which contained data on more than 1 million donors from 1968 to 2002. The researchers concluded that there is no link between frequent blood donation and risk cancer diseases. Moreover, among male donors there was a decrease in cancers such as liver, lung, colon, stomach and larynx cancer. The risk of cancer decreased the more often men donated their blood. As already mentioned, scientists explain the reduced risk of cancer by a decrease in iron reserves in the body.

However, non-Hodgkin's lymphoma (a malignant blood disease) was more common among donors than among ordinary people. However, this disease was recorded only in those donors who donated blood before 1986. Therefore, these data should be treated with caution, Dr. Etgarn said.

Additional study of the reasons for the development of lymphoma in donors is now required. Since many people donate their blood, the message that it may be in any way dangerous should be seriously examined. Still, Dr. Etgarn believes that “our study shows quite clearly that donors do not have an increased risk of developing malignant diseases.”

The Moscow Main Territorial Administration (MSTU) of the Central Bank of the Russian Federation called on banks to strengthen control over the condition of banknotes and coins arriving at the cash desks of credit institutions. On this occasion, a circular was sent out, which refers to the discovery of signs of radioactive contamination of banknotes in packages that banks hand over to MSTU branches, writes Novye Izvestia.
