APLASTIC ANEMIA
Aplastic anemia (a-PLAS-tik uh-NEE-me-uh) is a rare and serious blood disorder in which bone marrow stops making enough new blood cells. Bone marrow––the spongy material inside bones—makes new blood cells called stem cells. Stem cells normally develop into three main types of blood cells: red blood cells, white blood cells, and platelets. Each type of blood cell has its own functions in the body.
It is normal for blood cells to die. The lifespan of red blood cells is about 120 days. White blood cells live less than 1 day. Platelets live about 6 days. As a result, bone marrow must constantly make new blood cells.
The term "anemia" is most often used to mean a condition in which a person’s number of red blood cells is too low or their red blood cells do not carry enough hemoglobin (HEE-muh-glow-bin). However, in aplastic anemia, normal production of all blood cells—red cells, white cells, and platelets—slows or stops. This is because the stem cells have been damaged. The cause of this damage is often unknown
