Is it good or bad to donate blood regularly? Are there any benefits and disadvantages of donating bl

I think that people who donate blood repeatedly have a significantly lower blood viscosity, hematocrit, fibrinogen, and red blood cell electrophoresis than the normal value, so regular blood donation can prevent cardiovascular and cerebrovascular diseases. Blood donation can reduce blood lipids, and if the blood lipid level is high for a long time, it is easy to cause diseases such as arteriosclerosis. ‍‍

When the blood lipid concentration in the blood is at a high level for a long time, it can be called "blood viscosity", and when the blood is viscous, it is most likely to cause fat to attach to the blood vessel wall of the human body, which can lead to the occurrence of diseases such as arteriosclerosis. People who donate blood regularly, after donating blood, will reduce the total amount of blood, so that the blood in the blood vessels will be naturally diluted, which will promote the decrease in blood lipid concentration levels, and thus reduce the number of atherosclerosis. Therefore, it is beneficial to lower blood lipids. ‍‍

Of course, it is beneficial, unpaid blood donation has a certain impact on personal values, and at the same time, it also allows the blood donors themselves to be comforted and feel comfortable, and they will be more positive and sunny to live. ‍‍

This is a very good thing. But don't do it too often, it's definitely good to donate blood once a year.

I think the disadvantage is that after venous blood collection, there is more or less blood clotting at the wound during the process of hemostasis, and the blood coagulated inside the blood vessel may be affected by the blood due to the fast blood flow, enter the blood circulation, and form a thrombosis. Therefore, people with high blood lipids and fragility of blood vessels are not recommended or allowed to donate blood. ‍‍

Unpaid blood donors are entitled to free medical check-ups, which is a right and an obligation of blood donors. In order to ensure the quality of the blood collected, blood donors are subjected to a number of physical examinations, including tests for hepatitis B virus and HIV. So I think it's advantageous. ‍‍

I think it's good to be able to provide better help to those who need help.

I think it is beneficial to cardiovascular and cerebrovascular health, and the whole blood viscosity, hematocrit, fibrinogen, and erythrocyte electrophoresis in the repeated blood donation group are significantly lower than the normal values, which can be inferred that regular blood donation can prevent the occurrence of cardiovascular and cerebrovascular diseases. ‍‍

I think it's good to be able to help those in need.

I think this depends on the physical condition, if the physical condition is already anemia, it is recommended that you still, it is better to pay attention

The biggest advantage of "blood donation" is that it can help patients, and it is also a manifestation of the benevolence of unpaid blood donors. At the same time, it can promote the metabolism of the human body, which is a kind of behavior that benefits others and self. In addition, according to the regulations of each region, blood donors and family members can also enjoy corresponding preferential policies for blood use.

Regular blood donation is not harmful to the body, nor is it good, I have insisted on donating blood regularly for 10 years, and my body has not been affected. Regular refers to donating blood more than 2 times a year, and I donate blood at intervals, and I donate platelets on average once a month.
