Definition

Anemia is a low level of healthy red blood cells (RBCs). RBCs carry oxygen from the lungs to the rest of the body. When red blood cells are low, the body does not get enough oxygen. This can cause symptoms such as fatigue, pale skin, or irregular heartbeat.

Autoimmune hemolytic anemia is caused by the destruction of RBCs. It can be a serious, fatal condition that requires care from a doctor.
