Quick Answer: What Kills Red Blood Cells?

What causes the immune system to attack red blood cells?

When you have AIHA, your immune system makes antibodies that mistakenly attack your own red blood cells.

Other diseases and medications can also cause autoimmune hemolytic anemia..

What causes red blood cells to die prematurely?

It mistakes red blood cells for unwanted substances and attacks them, causing them to die early. This leaves a person without enough red blood cells.

What drugs increase red blood cells?

Recombinant erythropoietin drugs are known as erythropoietin-stimulating agents (ESAs). These drugs are given by injection (shot) and work by stimulating the production of more red blood cells. These cells are then released from the bone marrow into the bloodstream.
