What is the harm of donating blood to the body As the title Thank you

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. It is worth reminding that if you take a lot of tonic and are inactive, it will not be conducive to the digestion and absorption of nutrients, resulting in gastrointestinal dysfunction, and you will gain weight due to excess calories.

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.

There is no harm at all@@!On the contrary, the advantage is that you can speed up your new Chen to give birth to new blood, and you can use blood donation to check if you have hidden problems, what harm can there be @@?Don't worry about donating blood, you can still save people! That's a good thing

First of all, there will be some small effects, such as you will eat a lot of things here, your face will not look too good in the last few days, and it will be better in a few days, I often donate blood, because it can help my blood add something fresh, which is harmless to itself, but remember that your blood vessels are easy not to be punctured, and do not let him get infected. Hehe.

Is blood donation a health hazard?

When it comes to donating blood, some people are very nervous and even a little panicked, thinking that blood donation will have adverse effects on their health, but in fact, this view has no scientific basis.

A healthy, normal hematopoietic person has a stronger ability to regenerate blood, especially for women, the hematopoietic function is better. Therefore, occasionally donating 200 400 ml of blood will not affect your health. After donating blood, the amount of blood lost can usually be replenished within a few days through normal hematopoietic function.

Some people feel dizzy and have some adverse reactions after donating blood, which is mainly due to lack of common sense of blood donation, high mental stress, or blood donors who do not have enough rest before donating blood, excessive fatigue, hunger, alcohol and smoking.

The total amount of blood in the human body accounts for 7 8 of body weight. A healthy person loses 10% of the total amount of blood at a time, which will have no effect on the human body; With a loss of more than 20, hypovolemia manifestations may occur, making it difficult to perform normal activities; A loss of more than 30 will bring certain dangers. Therefore, for healthy people who have met the criteria after a pre-transfusion medical examination, donating 200,400 millilitres of blood will not affect their health.

After donating blood, as long as you properly supplement nutrition and rest for 1 or 2 days, you don't have to worry about harm to your health at all.

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.

In general, there is no harm.

It's better not to advertise the physical benefits of donating blood, which I have always thought is a bit far-fetched.

Donating blood does not affect the health of blood donors, and many blood donors continue to donate blood for many years.

The benefit of donating blood for so many years is that you can participate in and promote the process of unpaid blood donation, so that your life can be more fulfilling.

I learned some blood knowledge, paid more attention to my physical health, paid attention to a light diet, and kept my blood lipids not high.

After donating blood, if you or your family members use blood in the hospital, you can be reimbursed for the cost of blood use.

If you donate blood more times, you can get a reward from the state.

Human blood is made up of four parts: plasma, red blood cells, white blood cells, and platelets.

Plasma is the product of food and water that people eat, after digestion, accounting for about 55% of the total amount, and can be replaced at any time;

The main function of red blood cells is to transport oxygen, accounting for more than 40%, and the lifespan is about 120 days;

White blood cells are antiviral, platelets are plugged to stop bleeding and maintain blood vessels, and the lifespan is about 10 days.

The interval between two whole blood donations, which is about three months in the world (only half a year in Chinese mainland), is determined according to the lifespan of red blood cells.

The interval between two platelet donations can be two weeks, also depending on the lifespan of the platelets.

The reference value of a healthy person's platelet count is between 100 and 300, and more than 150 can donate a ** amount of platelets, which is still above 100 after donation.

After donating whole blood, the red blood cells in the body are also within the normal range, and the red blood cells will return to their original state in more than half a month.

Three or two days after the platelet donation, the platelet count in the donor's body can return to its original state.

Blood tests will be done before donating blood, and donating blood and platelets will not cause any harm to the donor.

Donating blood has no effect on the donor's body, and it will work normally on the day of donation, just not too drastic.

The advantage is that an appropriate amount of blood donation can reduce the viscosity of blood, prevent cardiovascular and cerebrovascular diseases, improve hematopoietic function, and reduce the incidence of cancer.

However, donating blood can lead to low immunity and easy to get sick.

That's it, I hope it helps!
