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 a periodic loss of 12% of a given volume not only has no effect negative influence for health, but also works as a kind of training, activating hematopoiesis and stimulating 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. Unpleasant sensations donor are 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 it is not recommended to do heavy activities on the day of the procedure. 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.
To fully provide the healthcare system required quantity blood, 40-50 people out of 1000 should be donors. 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 blood diseases ( hematopoietic 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 inflammatory process or traces of alcohol, increased body temperature 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 medicines 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 consume fatty, dairy, meat food, eggs, smoked meats, 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 more liquid to compensate for 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 becoming fat for those people who, having misunderstood the recommendations for nutrition, begin to heavily 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 impact 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.
Donation has been clinically proven to reduce 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 suitable protein composition Donor blood can be transfused into a recipient regardless of gender, age or nationality.
One blood donation can save three lives, according to representatives of the Red Cross. The benefits of blood donation are not limited to those for whom it is intended. Blood donors also improve their health by donating blood.
We often hear the expression that it is much more pleasant to give than to receive. This is backed by research - people who do good deeds strengthen their mental health And:
Let us remind you that any healthy person from 18 to 60 years old and weighing more than 45 kg can donate blood.
Donating blood reduces the risk of heart attack and heart attack. A 2013 study found that blood donation helps reduce bad cholesterol levels in the blood. This is the prevention of diseases of the cardiovascular system.
Regular blood donation reduces the iron content in the blood. This is also a prevention of a heart attack, since it is provoked by excess iron in the blood.
In 2008, scientists proved that donating reduces the risk of developing cancer of the liver, intestines, esophagus, stomach and lungs. https://academic.oup.com/jnci/article/100/8/572/927859 Regular blood donation increases blood flow in the body. This protects against the development of cancer.
Another advantage of blood donation is free testing. Before you donate blood, doctors measure your pulse, blood pressure, temperature and hemoglobin level. These options will help determine if you have health problems. Additionally, you will be checked for the presence of hepatitis, HIV, syphilis and others. dangerous viruses.
Blood donation helps you lose weight. During one blood donation, the body loses approximately 650 kcal, which is equivalent to 1 hour of running.
After you donate blood, your body begins to work hard to replace the blood lost. This stimulates the production of new blood cells. This effect improves health.
The harms of blood donation
Blood donation is not harmful to health if it is carried out according to the rules. For each donor, doctors should use only new and sterile supplies to avoid contamination.
When donating blood, it is drained through a vein. Loss of some blood causes a fall blood pressure. Blood loss stimulates the bone marrow, from which young red blood cells enter the blood. After donating blood, a person feels an influx of strength, freshness, and vigor. Feeling better. Water from the cells rushes into bloodstream. Thickened blood is liquefied, toxins from tissues enter the kidneys through the blood and are eliminated from the body. This information contains the answer to the question: is it useful or harmful to donate blood to men and women?
Supporters alternative opinion give arguments against. And, they are partially right. Because there are contraindications against donating blood.
IN old times, was considered effective medical procedure in the treatment of many diseases. Since the beginning of the twentieth century, the practice of blood transfusion to a victim in case of severe blood loss began to develop. There was a theory according to which blood transfused from a young man to an old man could have a rejuvenating effect.
The pioneers conducted experiments on themselves. After several successful experiments, followed by the death of the Soviet scientist Alexander Bogdanov. It turned out that not all blood is suitable for transfusion from one person to another.
Four are open. In addition to them, there is a distinction between blood that has the Rh factor and that is free from it.
Failure to comply with the rules of blood transfusion leads to the destruction of red blood cells in the recipient of blood and fatal outcome. Therefore, for those who are going to present special requirements for the donor.
Doctors say that the blood donation procedure is beneficial for the donor. But, there are the following obstacles to donating blood:
- It is required to observe the recommended intervals between blood donations;
- There should be no contraindications due to the health status of the donor;
- The donor should not have infectious, invasive or physical diseases;
- It is necessary to take into account his well-being: temperature, pressure, etc.;
- The donor should not have tattoos, piercings, etc.;
- You cannot donate blood immediately after returning from abroad.
Regarding the benefits of donating blood, you should determine the gender of the donor. To the question: is it useful or harmful to donate blood to men, the answer is clear: useful, provided there are no contraindications to donation. Men over forty benefit from bloodletting more than younger men.
This is not the case with women. It is known that every month, during the period, the body loses a noticeable portion of blood, so ladies need bloodletting to a lesser extent than gentlemen. Therefore, answering the question: is it useful or harmful to donate blood to women, you can answer: you need to know the age of the potential donor.
Bleeding brings women childbearing age less benefit than men. Therefore, the intervals between blood donations should be longer for them than for men. But, bloodletting brings more benefits to older ladies than to young ones, due to the lack of critical days.
Preparation
Routine procedures are carried out in advance. Assess the health status of a potential donor. It is necessary to make sure that the loss of blood does not harm the health of the donor, and that the donor himself does not suffer from diseases that can be transmitted to the recipient.
The future blood donor has the presence or absence of the Rh factor. They carry out tests for the content of pathogens of AIDS, syphilis, viral hepatitis and other diseases in the blood. Age restrictions no for donation. The blood of an old man and a young man is equal.
And here, individual characteristics the donor is provided decisive influence for suitability for blood donation. People who have undergone certain operations, as well as those with tattoos and piercings and body weight are not allowed to donate.<50 кг. В особом порядке рассматривают пригодность к донорству беременных и кормящих матерей
Donation should not be abused. Excessive or too frequent does not allow it to recover sufficiently. There are a number of diseases in which donation is contraindicated. Failure to comply with such rules for a blood donor can cause irreparable harm to health.
Professional blood donors become so accustomed to donating blood that they feel an irresistible need for it.
What are the benefits of donating blood:

Blood donation - free procedure. To recuperate, a person is given a paid day off. The blood collection process lasts about 30 minutes.
Sometimes, a transfusion from a donor involves taking not blood, but some part of it. For example, red blood cells, white blood cells or plasma. In this case, the donor's blood passes through a centrifuge, where the components necessary for transfusion are selected, and the remaining parts of the blood are returned to the donor vessel.
According to studies conducted in Finland and the USA, people who regularly take donor blood, are susceptible to atherosclerosis and heart attacks to a much lesser extent. Also, according to the observations of foreign researchers, blood donors live 5-8 years longer than the average person.

Therefore, contrary to fears, a person has no chance of becoming infected with anything.The loss of blood experienced by the donor also does not pose any threat. Usually about 450 ml of blood is taken at a time, which is no more than 10% of its total volume. Almost immediately after this procedure, a person can get up, drink a cup of tea and go home. Within a day or two, the amount of blood in the donor’s body will be replenished.

Nowadays, many potential donors are interested in the question: is it useful to donate blood?
The benefit of donation for the body is that blood donation prevents cardiovascular diseases, diseases immune system, pancreas, atherosclerosis, digestive disorders and develop resistance to blood loss during accidents, operations, burns or accidents. Also, donation can remove ballast from the body in the form of excess blood and its elements, prolong your youth by stimulating bleeding and self-renewal of the body and, of course, bring considerable satisfaction from the good deed you have accomplished. Do you still doubt whether donating blood is beneficial?
Donation activates the bleeding system - red cells bone marrow, and improves immunity. The body is affected by the unloading of the spleen and liver, and according to the latest data, the risk of developing atherosclerosis, thrombosis and coronary disease hearts. Finnish scientists claim that men who donate blood have a tenfold reduction in the risk of heart attack, and American researchers report that male donors are much less likely to suffer from heart attacks. Regular bleeding keeps cholesterol levels low.
When donating blood, all so-called “storage diseases” are prevented, which include gout, digestive and pancreatic disorders, as well as diseases of the basal metabolism and liver. Blood donations are also useful for preventive purposes.
If you're still wondering if donating blood is healthy, remember that donors who donate consistently are some of the healthiest people in the world! According to WHO, donors live 5 years longer than the average person.
Blood donors do not have to worry about their health, since absolutely all procedures are performed using disposable sterile systems under the supervision of a physician.
A capable person who has reached the age of 18 and has passed medical examination and has permanent registration. He is entitled to two days off, one of which falls on the day of blood donation, and the second at the donor’s choice, determination of the blood type, blood test, blood test for diseases such as HIV, syphilis, hepatitis B and C, as well as a doctor’s examination.
Infection of the donor is absolutely excluded, since doctors use individual disposable systems for blood collection, and the sensation of blood donation is purely individual, but most donors do not experience it at all painful sensations. Some people feel a surge of energy and a desire to work, and absolutely everyone feels a lot of energy. positive emotions from helping to save a life!
Within 30-40 days, the blood composition is completely restored. The blood donation process is absolutely safe and does not cause any harm to the body. To ensure complete safety, the donor’s blood is quarantined and after six months the donor must undergo a re-examination, based on the results of which the blood is supplied to city hospitals. So do you think donating blood is beneficial?
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 only learn about their ailments when the disease manifests itself on physical level and progresses. This is one of positive points, demonstrating why being a donor is beneficial. 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. Bone marrow, on the other hand, works hard to produce new blood cells to make up for what was lost. Good influence moderate blood loss also affects the cardiovascular system.
Donating blood for the donor’s body is a small stress, thanks to which it is activated protective functions. 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 and coronary heart disease, since their veins are constantly cleared of excess bad cholesterol. According to several studies, donation prolongs life by at least 5 years.
Donating blood for donation is also useful psychological point vision. 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 can become a donor who does not have infectious diseases person over 18 years of age. The upper age limit was removed not long ago, so even people over 60 years of age, provided wellness 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 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 the presence of 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 advisable 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 harms and benefits of donating blood

Of course, you do not need to donate blood on days when you are sick or feel unwell. It is also not recommended to donate blood more often than once every 60 days, and plasma - more often than once every 2 weeks. In general, you can donate blood 3-5 times a year, and plasma 6-12 times. The rest of the time the body should have the opportunity to recover.Any person over 18 years of age who has good health and can physically donate blood without harming one’s own body. The standard amount of blood that can be taken from a healthy person without affecting his well-being and physiological functions is 450 ml.
Before donating blood, you will be thoroughly examined by a doctor who will confirm that the process is safe for the donor. In general, humans are evolutionarily adapted to blood donation, although previously this was encountered only during injuries and therapeutic bloodletting. In addition, bloodletting in moderate doses has a very positive effect on the human body and makes it healthier.

When donating blood, the hematopoietic system (red bone marrow cells) is activated and improved immune defense. Those organs that participate in the process of excretion are “unloaded” dead body red blood cells, namely the spleen and liver.
The latest data from American and Finnish scientists indicate that with periodic blood donation total risk the development of coronary disease, thrombus formation and atherosclerosis is reduced tenfold.
Male donors are much less susceptible to heart attacks, they suffer fewer heart attacks, and their blood cholesterol levels are kept low.
Interesting fact: if a woman donates plasma before planning a pregnancy, the baby will be a girl, and if a man donates plasma, it will be a boy.

Don’t be afraid to donate blood, because the donor’s blood is mandatory Before delivery, it is checked for infections. If any infections are detected in the blood, the donor is offered to undergo a course free examinations, as well as treatment if necessary. Also, the editors of the website www.rasteniya-lecarstvennie.ru and I want to assure readers that
harm from donating blood
cannot be applied to the donor during the collection process itself, because all systems for this have long been disposable.After treatment, the donor does not have the right to donate blood for another 6 months. But even after quarantine, blood will need to be tested again, as new infections may be detected.
And remember that your blood can save someone's life. Maybe to your acquaintance, friend, and maybe to you. After all, no one is safe from misfortune.
Question for doctors: how harmful is it to donate blood? and is it harmful at all if I have a strong body?
Alexandra
It is not harmful to a healthy person.
I donate blood regularly, and I don’t find any downsides to my health.
“For a healthy person, the procedure for donating plasma is absolutely safe, harmless and, moreover, useful. According to WHO, blood donors who constantly give blood/plasma live on average 5 years longer than the average person” (http://rosplazma.ru/question /).
By the way, you can ask questions directly to doctors - for example, in the “Specialists Answer You” section of the website transfusion.ru.

I’m not a doctor, but I know that this is useful due to the fact that the blood is renewed, becomes “cleaner”, and due to this everything works better internal organs. But at the same time, you need to eat very well so that hemoglobin and other things return to normal. Even in ancient times, when there was no real medicine, almost all diseases were treated with bloodletting.
Lyudmila Falko
I was working in a hospital, one day an aunt came in, she was ugly, she used to be a donor for many years, she said: “At least do some bloodletting...” - it’s so scary... like a drug addict, she probably feels bad “without this business!”
Who am I here?
I donated blood for a long time.
since 2000 Honorary donor.
I donated a total of 24 liters.
I donated it for free, because I was convinced of the need for donation.
None negative influences was not on the body.
Is donating blood harmful or beneficial?

About bruises. They usually don’t happen if you don’t remove the bandage ahead of time (I wear a tight bandage for at least 3 hours). But if a bruise has already appeared, hepatrombin or troxevasin will quickly help.
About donation. According to American researchers, donors are ten times less likely to suffer heart attacks. Regular blood donation keeps cholesterol levels low.
Donating blood is useful for the prevention of all “storage diseases” - atherosclerosis, gout, digestive disorders, pancreas, liver, and basal metabolism. And for the prevention of diseases of the immune system, blood donations are useful: after all, this is also associated with the renewal of the body. In scientifically proven doses, bloodletting has a stimulating effect.
Donation is useful for preventing blood loss: in the event of an accident, a wounded donor has a much greater chance of survival.
Probably, there is no need to say much about the benefits of medical examination - you must agree that people usually do not pay preventive visits to doctors every 2 months. At each visit, the donor undergoes an in-depth examination (and quickly and free of charge).
I also consider increased self-esteem and emotional uplift from a good deed to be a plus for health :-)).
You can read about donation on my blog. Welcome!

I needed to donate blood for my daughter. They didn’t take it from me, they said that I needed to infuse the blood myself. I think that this is not useful for everyone, but it is noble... And the bruise was caused by the unprofessionalism of the medical staff or your friend immediately threw away the cotton wool and did not keep his arm bent after drawing blood.
Is donating blood harmful to the body?

“Not all yoghurts are equally healthy!” (c)
My soul mate (also a medical luminary) highest category) strongly advises me not to donate blood.
Also, by the way, she does not favor flu vaccinations.

Donating blood is even useful, at least that’s what doctors think. Back in the Middle Ages, bloodletting was used to treat many diseases. For some conditions it is still used today. Bloodletting is useful for hypertension and for women in menopause. It is also useful for men, as it adapts the body to possible blood loss, injuries or stomach ulcers.
Regular blood donation triggers self-renewal processes in the body. Numerous studies show that donating blood serves as a preventive measure for cardiovascular diseases. In men who donate blood regularly, the risk of having a heart attack is reduced several times.
So think about whether donating blood is harmful or beneficial. We think not. In addition, you get moral satisfaction from donating blood because you help people, which guarantees good mood for a long time.
Yuri Viktorovich Vedeneev
Donating blood is not harmful. Human body evolutionarily adapted to bloodletting: this is a universal reaction mechanism in case of injury, and in women, in general, it is part of the functioning of the body.
Exiled to planet Earth
I took it myself at one time... and no one thought it was useful... .
Blood is renewed in the human body every 4 years, and blood donation, i.e. blood loss, provokes it to start the process of producing new red blood cells, thereby knocking down normal work... .
Only one-time donations of blood at large intervals of time can be harmless, since nature, too, in the process of evolution, took care of this using examples of injuries with large blood loss....
Alas!!! Frequent and regular blood donation leads to the body adapting to the constant replenishment of blood.
In case of failure to donate blood, after a certain period of time the person is overcome headache, pressure.
Roughly speaking, this unpleasant malaise begins. People who were once donors themselves repented that they were too keen on bloodshed.

For healthy body- not harmful.
According to foreign researchers, donors are ten times less likely to suffer heart attacks. Regular blood donation keeps cholesterol levels low.

Donation is useful for preventing blood loss: in the event of an accident, a wounded donor has a much greater chance of survival.
Probably, there is no need to say much about the benefits of clinical examination - you must agree that people usually do not pay preventive visits to doctors every 2-3 months. The donor undergoes an examination at each visit (and quickly and free of charge).
I also consider increased self-esteem and emotional uplift from doing a good deed to be a health benefit.

On the contrary, there are even medical indications to donate blood. Bloodletting is useful for people with increased blood pressure, women during menopause. The fact that, from the Middle Ages until our century, many diseases were treated with bloodletting is also in favor of donating blood. Nowadays, hirudotherapy (treatment with leeches), which is essentially the same bloodletting that benefits the body, is widely promoted.
Regular blood donations are also useful because they train compensatory mechanism human body.
According to WHO, blood donors who constantly give blood live on average 5 years longer than the average person.
As an example, I can give one case where donation saved a man’s life. Due to the suddenly opened stomach bleeding middle-aged man honorary donor, lost a lot of blood. The man had virtually no chance of survival, experienced doctors assured, if not for many years of donation. Accustomed to regular blood loss, the body quickly mobilized its strength. The same compensatory mechanism turned on. The patient soon recovered.
