Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types.

Symptoms may develop slowly or suddenly. Fatigue, frequent infections, rapid heart rate and bleeding may occur.

It is more frequent in people in their teens and twenties, but is also common among the elderly

Aplastic anemia is present in up to 2% of patients with acute viral hepatitis.
