Anemia is a low level of healthy red blood cells (RBCs). RBCs carry oxygen from the lungs to the rest of the body. Low levels of RBCs make it hard to get enough oxygen throughout the body. 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 will need medical care.

This type of anemia is caused by a problem with the immune system. For some reason, the immune system starts to make antibodies that attack red blood cells. Medicine or other illnesses may cause this change in the immune system.
The risk of autoimmune hemolytic anemia may be higher in those with:
Symptoms may include:
You will be asked about your symptoms and past health. A physical exam will be done. Anemia may be suspected based on symptoms. A blood test will confirm low levels of RBCs. There are different types of anemia. Other tests will confirm the type.
Mild cases of anemia may not need treatment. They may get better on their own. If treatment is needed, steps may include:
The spleen is a small organ near the stomach. It helps to clear out old and damaged RBCs. Anemia can cause an enlargement of the spleen. This can then make anemia worse. The spleen may need to be removed if it is causing problems.
There are no steps to prevent autoimmune hemolytic anemia.
