Why doesn t blood donation affect my health?

Our body has a strong compensatory function in hematopoiesis and blood storage, and the life of a healthy organism lies in activity, and the blood circulation of a healthy organism is no exception, which is in the process of continuous metabolism from beginning to end; At the same time, the blood of the body of the student mental health case is not running at full capacity, and only 80% of the total blood volume of the whole body is actually involved in the blood circulation, and the rest is stored in the "human blood bank" such as the liver and spleen. After quantitative blood donation, the blood in the blood bank of student mental health cases will be released immediately, and it can be completely supplemented in a short period of time without affecting the body's function. At the same time, blood donation must go through a strict physical examination before donation, and those who meet the criteria can donate blood Students' mental health cases not only ensure the health of blood donors, but also ensure the safety of blood recipients.

The Blood Donation Law stipulates: "The State implements a system of unpaid blood donation, and encourages healthy citizens between the ages of 18 and 55 to donate blood voluntarily.

Friends have more or less had the experience of donating blood, can help others, this feeling is still very happy, and donating blood can also help themselves, there is a saying that blood donation is conducive to the activation of the hematopoietic system, is conducive to reducing blood viscosity and improving immunity, etc., but these have not been confirmed.

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.

As science becomes more and more advanced, so does the importance of physical health. Many people believe that blood donation is to promote human blood circulation and enhance the function of human hematopoietic stem cells, so many people will choose to donate blood regularly without compensation. So, why doesn't blood donation affect your health?

Is it good for the body? Medical studies have shown that as long as the amount of blood loss in the human body does not exceed one-tenth of the total blood volume of the human body, then the body function can quickly replenish the amount of blood temporarily lost by the human body. The amount of blood donated each time is only one-twentieth or even one-twenty-fifth of the total blood volume of the human body, so blood donation will not affect the health of the body, but will be beneficial to the body.

Every day, every part of a person's blood goes through a series of steps of flowing, filtering, washing, and then filtering out the parts that are not useful to the body. Therefore, the blood of the human body will have fresh blood and aging blood every day, as well as the useless part that is filtered out, and then it will be constantly renewed. Every time you donate blood, almost all of you donate 200 milliliters of blood, and the total blood volume of the human body is about 4,000 milliliters to 5,000 milliliters, and the blood donated only accounts for about one-twentieth to one-twenty-fifth of the total blood volume of the human body.

At this time, the human body will quickly replenish the blood lost by the human body due to blood donation through neuromodulation and humoral regulation in the body, so that the blood can be replenished quickly. There are also red blood cells lost due to blood donation, which are produced at an accelerated pace by our bone marrow hematopoietic stem cells. Therefore, donating blood will not affect your health.

You may feel dizzy, thirsty, and want to drink water after voluntary blood donation, but this is not a bad effect of blood donation, so don't worry. This is because in the process of neuromodulation and fluid regulation in our body after blood donation, the human body needs to replenish food and water to maintain the body's temporary nutrient deficiency caused by blood donation.

Blood donations are generally between 200 and 400 ml.

The water of the plasma can be restored in one to two hours.

Plasma proteins recover in one to two days, and blood cells recover in one to two weeks.

So donating blood does not affect health.

Blood is mainly composed of plasma, blood cells, and platelets, and blood cells are like small lifeforms, which are metabolized all the time, so that the total amount of blood in the body is relatively constant.

The total amount of blood in the human blood circulation is very large, a certain amount of blood donation will not affect the health of the body, the amount of blood donation only accounts for a small part of the human blood, and the original level will still be reached through diet after blood donation.

Whether blood donation will affect physical health has been debated for a long time, in the short term, blood donation will consume some energy of the human body but will soon be able to recover, after all, girls still have hundreds of milliliters of blood every month, the regulation of human body functions can fully adapt to this change, but in the long run, it may have an impact on the immunity of old age, these have not yet been judged, so it cannot be arbitrarily said that blood donation is bad.

The blood of the human body is flowing and filtered and cleaned every day, and the useless things will be filtered out, and the red blood cells will continue to regenerate and transport fresh blood.

Friends have more or less had the experience of donating blood, can help others, this feeling is still very happy, and donating blood can also help themselves, there is a saying that blood donation is conducive to the activation of the hematopoietic system, is conducive to reducing blood viscosity and improving immunity, etc., but these have not been confirmed.

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.
