Can blood donation drop immunity?

There are many myths related to blood donation that stop many from doing this good deed. One of them is misinformation that blood donation causes a significant drop in immunity levels, making you weak and exposed to infections.
However, according to health experts1, there is no reason to be scared of low immunity levels, as there is only a slight drop in red blood cells which is temporary.
“This small drop stimulates the bone marrow to produce blood cells, white blood cells, and platelets. The white cells improve the immunity levels as well,” said Dr. Snehal Majumdar, Director of Transfusion Medicine, Blood Center, Ruby Hall Clinic.
Doctors say blood returns to normal in a few weeks and if the body needs more antibodies in the bloodstream, it produces them extremely quickly.

Does blood donation make you weak?

“No, it doesn’t. A Blood donor is accepted only if the hemoglobin is 12.5 g/dL or more, and it is properly checked before donation. Also, one unit of blood donation decreases the donor’s hemoglobin by just about 1 g/dl. This does not cause weakness at all,” Dr. Majumdar said.
Dr. Majumdar added that this small drop in blood amount only stimulates the bone marrow to produce more blood cells.
