Aplastic Anemia

Aplastic anemia is a rare but serious blood disorder that occurs when your bone marrow cannot make enough new blood cells for your body to work normally. It is also known as Bone Marrow Failure. 

It occurs because of damage to stem cells inside bone marrow, which is the sponge-like tissue within your bones. Many diseases and conditions can damage the stem cells in bone marrow. As a result, the bone marrow makes fewer red blood cells, white blood cells, and platelets. 

The most common cause of bone marrow damage is from your immune system attacking and destroying the stem cells in your bone marrow, which is a kind of autoimmune disorder.
