Overview
Autoimmune hemolytic anemia (AIHA) occurs when your immune system mistakes red blood cells as unwanted substances. As a result, your body produces antibodies that destroy red blood cells, which can lead to a low amount of red blood cells (known as anemia ).

Management and Treatment
Autoimmune hemolytic anemia treatment usually involves addressing underlying conditions first. For example, if your AIHA is linked to lupus, then your healthcare provider will probably start by treating the lupus directly. If AIHA is caused by lymphoma, treating the lymphoma directly is important.
Prevention
It’s not always possible to prevent autoimmune hemolytic anemia. But if you have a viral infection or use medications that are commonly linked to AIHA, then your healthcare provider can monitor your situation in an effort to reduce your risk of developing the condition.
