Aplastic anemia occurs when stem cells fails to produce enough mature blood cells. At this time, the bone marrow and the hematopoietic stem cells in the bone marrow are damaged. As a result, red blood cells, white blood cells and platelets simultaneously fail to function efficiently.
Different causes can lead to aplastic anemia. Although some causes remain unknown, possible causes include heredity, immune disease, drugs, exposure to chemicals, and radiation.
Aplastic anemia is rare but can occur in people at any age. Generally, it occurs more frequently in those who are in their teens and twenties. It may occur suddenly or progress gradually over time.
