Is blood donation really that harmful?

September 23, 2023

Blood donation is the voluntary donation of whole blood, plasma or blood components by a donor without receiving any compensation. This gratuitous act of blood donation can help save the lives of countless patients in serious illnesses, but it can also cause minor harm to oneself.

Increased Chances of Infection

We know that blood transmission is one of the main modes of HIV transmission. Although regular blood donations are guaranteed to be sterile in principle, there is no 100% guarantee that no one will be infected with HIV, hepatitis B or other blood-borne infectious diseases. Therefore, blood donation can increase the chance of HIV infection to a certain extent.

Causes minor trauma to blood vessels

Even blood vessels are not an exception. Although the trauma caused is minimal, frequent blood donation can cause multiple wounds to the blood vessels, making them hard and inelastic. Moreover, when donating blood, there is a risk of rupture of the blood vessels when the traumatized parts of the vessels are exposed to unknown external forces.

Possible "addiction"

It is true that regular blood donation can promote the increase of the hematopoietic function of the body, and a small number of young people who have a strong blood flow will feel the swelling of blood vessels throughout the body if the hematopoietic function is further enhanced, and only regular blood donation can relieve them of that swelling feeling.

Dulling brain response

A short period of blood donation can cause a lack of blood supply to the brain, which can cause dizziness. This is especially noticeable in people who are anemic. For this group of people, regular blood donation not only has no better effect, but also leads to regular lack of oxygen to the brain, making the brain less responsive and less agile, especially for brain workers.

Accelerated organ aging

The human body has a total of about 4000-5000 cc of blood, of which the organs hold about 20% of the blood in stock, which can be quickly replenished in the event of an accidental injury to the body. However, human organs do age, and in the event of an accidental injury due to age and weakness, the body no longer produces blood as quickly as it did when you were younger. At this time, you will have an increased mortality rate due to insufficient blood supply from excessive bleeding.
