Does donating blood affect health, and does donating blood affect health?

No, it won't. The total blood volume of an adult is about 4000-5000 ml. The weight standard for blood donation is set at 50 kg for men and 45 kg for women.

A person donates 200-400 ml of blood at a time, accounting for only 5%-10% of the total blood volume, plus the blood drawn out is the blood of the peripheral blood vessels, the human body will automatically release the blood originally stored in the spleen, liver and other internal organs into the blood vessels, maintain a constant blood volume, and the water and inorganic substances lost after blood donation will be replenished in 1-2 hours; Plasma protein, which can be replenished within a day or two; Platelets, white blood cells, and red blood cells also return to their original levels. Therefore, blood donation will not affect the health of blood donors.

Therefore, healthy people donating blood according to the regulations will not have any effect on the body. After donating blood, the body's hematopoietic tissue will automatically accelerate hematopoiesis, and it can generally return to the original level after half a month. Appropriate nutrition is increased to provide sufficient raw materials for blood production, and the focus of supplementation is on protein, iron, vitamin B12, folic acid, etc., which are needed for hematopoiesis.

High levels of iron in the human blood can significantly increase the risk of heart disease, and donating blood in moderation can greatly reduce the amount of iron in the blood.

It will not hurt to donate blood in moderation, protect the puncture hole after donating blood, and properly supplement nutrition.

No, proper blood donation is not only harmless but also beneficial to the body, each of us has the ability to produce fresh blood, but it is not as easy to make people fat as blood often.

Proper blood donation does not affect health, but is good for the body, which is what some people call "exchange transfusion". However, if it is a woman, it is not suitable for physiological reasons to donate blood too much and frequently.

Under normal circumstances, a healthy person who donates 200---400cc of blood at a time will not affect the health of the body, and blood donation can also promote the production of new blood cells, which is beneficial to the human body.

No, I've already offered it twice and I haven't found anything bad.

Infrequent blood is good for health and promotes blood renewal, but don't donate more than 400cc at a time. That's it.

No, it will also promote the regeneration of fresh blood.

Blood donation is good for good health (good for metabolism), provided that it is in a regular medical institution and the practice is standardized.

No, it won't. The key is to have a correct understanding of blood donation....

Of course not, it's still good for the body.

Probably, it is advisable not to give often.

A normal person who donates no more than 400 blood should be no problem, it won't affect anything, I've donated.

No, no, no, it won't be good for health

200--400 should not be a big problem, unless you are usually weak, susceptible to colds, and weigh less than 100 pounds.

It will not depend on your physical condition as well as your health condition.

Dedicating one's bone marrow to the patients and rescuing those dying brothers and sisters is what a noble act of the erection group! With the development of bone marrow transplantation, more and more people have responded to the work of bone marrow donation. However, there are also many people who do not understand the process of marrow donation and lack knowledge in this area, and they are worried about whether marrow donation will affect their health.

Actually, this worry is unnecessary.

Many different types of blood cells in our body come from the same ancestor, superfluous orange hematopoietic stem cells. Not only can he continue to differentiate his offspring, but he can also reproduce cells that are exactly the same as his own. As a result, our hematopoietic function is endless.

When the old blood cells die, new ones grow in their place; When some hematopoietic stem cells are damaged, healthy stem cells are born soon to compensate for them. Our bodies work so well together. Pluripotent stem cells are not very numerous and are distributed throughout the bone marrow.

When donating bone marrow, only a small part of the bone marrow of the human body is extracted, and only a part of the pluripotent stem cells are lost, and the remaining pluripotent stem cells will be quickly replicated, and the hematopoietic function will completely return to normal in a short period of time. Therefore, bone marrow donation will not affect the hematopoietic function of the person.

Some people are afraid of the operation of donating bone marrow, and the following is an introduction to the operation of bone marrow collection: the donor is considered qualified by a comprehensive physical examination and then carried out under continuous epidural anesthesia or general anesthesia (the anesthesia method is the same as that of general surgery), and the part of bone marrow collection is mostly used in the iliac bone, which is commonly known as the large hip bone, and there are also sternum. The method of marrow collection is similar to that of a bone marrow aspirate.

A needle is used to aspirate several milliliters of bone marrow fluid. The amount of bone marrow taken depends on the patient's weight and the number of cells in the donor's bone marrow fluid. The number of bone marrow cells transfused should not be less than kilogram of the patient's body weight, and if it is too small, it is not easy to be transplanted successfully.

Therefore, adults generally need to donate about 800-1000 ml of bone marrow. In fact, there is a large amount of blood mixed with so much bone marrow fluid, so it is necessary to have a proper blood transfusion during the operation. When the number of cells reaches the required level, the operation is over.

After surgery, there will be pain in the surgical area due to the large number of puncture points, which usually disappears within two weeks. Many donors are able to return to work within 3-4 days after surgery, with the youngest donors being in the range of months. These all indicate that donating bone marrow is safe for healthy people.

Dear readers, you probably don't worry much anymore after reading the above, do you? When your friends or loved ones need it, you're going to lend a helping hand, right?

To summarize the disadvantages of blood donation that are hotly discussed on the Internet, it mainly focuses on the worry of contracting infectious diseases when donating blood, in fact, this is a completely unnecessary worry, because the needles and blood bags used in blood collection and supply institutions across the country are disposable medical consumables that have been strictly tested and qualified by the state, and there are strict operating procedures and requirements for blood collection.

1.As long as national blood donation regulations are followed, there is currently no evidence that blood donation is harmful to the body.

There are three national regulations on blood donation:

Between 200 and 400 ml of blood should be donated each time;

The interval between two blood donations should be more than six months;

Be in good health, have a normal physical examination, and be free of any infectious diseases.

Therefore, as long as the amount of blood donated is within the standard range, and people who are not frequently donating blood and are very healthy themselves, donating blood will not harm their health.

2.Long-term complications that really affect your health after donating blood are very, very rare.

Most of the statistical evidence currently collected on the health effects of blood donation focuses on an individual's experience or feelings. Such as dizziness, chest tightness, fatigue, etc. Some of the reasons here can be attributed to natural blood sickness, and some are due to some hypoglycemia from not resting well the night before or not eating.

Some are purely psychological. It is normal for some people to have these symptoms for more than half a year. It takes about half a year for the entire blood system to fully return to normal.

3.Blood donation is of great benefit to the whole society, the whole country, and the whole population.

Blood donation can help special patients, such as emergency patients who are in danger of dying due to massive blood loss and urgently need to replenish blood; Patients who have problems with their own hematopoietic function; Patients who require a major surgery at a specific time.

At present, in the more developed countries in the world, basically all the blood used for medical treatment comes from unpaid blood donations. And some countries in less developed regions will also vigorously call on people or spontaneously donate blood without compensation. In Japan, in particular, there is a blood donation campaign as part of the coming-of-age ceremony for every young person.

So every time you donate blood, it's very precious and really used to save lives.

It will not affect your health, as long as you supplement more nutrition after donating blood. It doesn't matter.

It will affect the body a little in a short period of time, but it will return to normal after slowly nutrition.

No. People have hematopoietic cells, even if they are drawn, they will recreate new blood, and remember to replenish the body more after donating blood.

If you donate blood under the premise of good health, it will not be affected.

My physique is relatively poor, and I often have colds all year round, so I have never donated blood, and I am usually a little anemic.

Proper blood donation will not affect your health.

It depends on the individual's physique, if the immune system is poor or anemia will definitely affect the health.

If the amount of blood donated is not too large, there is basically no health impact.

Some people may feel dizzy after donating blood, but it is good to rest for a few days.

Today is the 17th World Blood Donor Day. Blood is the most important component of the human body, and people cannot do without it. Many people have misconceptions about blood donation, thinking that blood donation is harmful to health, but it is not!

This will not affect your health, but it is best to donate blood when you are healthy.

I am 65 kilograms, donated 400 ml of blood last week, once every six months, I don't feel at all, but I feel very comfortable, I remember to go to a regular place to donate blood, I went to the Beijing Red Cross Blood Center to donate.

It is said that regular blood donation will improve the ability of blood cells to make blood.

Donating blood in moderation can reduce the viscosity of the blood.

When blood viscosity is at a high level, appropriate blood donation, especially the formed components in the appropriate amount of donated blood, can effectively reduce blood viscosity and prevent a variety of diseases.

Regular blood donations in men can prevent cancer.

British scientists have found that men's blood donation can prevent cancer, this is because the blood contains a lot of iron, and the level of iron in the human body is too high to promote cancer, regular blood donation can effectively reduce the level of hemothemia in the blood, so healthy men can receive the effect of cancer by donating blood regularly.

Participate in blood donation activities scientifically and reasonably, and it will not affect your health.

Formal blood donation locations, such as blood donation vehicles, are beneficial to your health.
