Osmosis video - Autoimmune hemolytic anemia

Autoimmune hemolytic anemia (AIHA) is a blood disorder that occurs when a person's own antibodies attack and destroy healthy red blood cells. The cause is not completely understood, but it may be associated with other conditions such as an infection, or leukemia. AIHA causes several symptoms, including fatigue, jaundice, shortness of breath, and an enlarged spleen.
