The list of causes of hemolytic anemia can be broadly categorized as being intrinsic or extrinsic.
Intrinsic Causes
The termintrinsicdescribes defects in the production of red blood cells themselves.

Those who survive may improve with a blood transfusion, light therapy, and medications.
Symptoms
Many of the symptoms of hemolytic anemia are not unlike those ofother types of anemia.
Left untreated, hemolytic anemia can cause serious and potentially life-threatening complications.
It has many causes, including genetic disorders, infections, and autoimmune diseases.

A complete blood count and other tests can help diagnose hemolytic anemia.
Treatments include a blood transfusion, IVIG, immunosuppressants, and a bone marrow transplant.
