Aplastic anemia is an acquired or inherited disorder related to bone marrow dysfunction. The bone marrow cannot produce sufficient red blood cells in this kind of anemia. It is because the bone marrow produces different types of blood cells. People undergoing chemotherapy or having diseases that damage bone marrow are at risk of developing this kind of anemia other than those who inherit the causes. Its treatment is more aggressive, including blood transfusions, bone marrow transplants, and medicines.
