Aplastic anemia is a rare blood disorder where the bone marrow fails to produce enough blood cells. This can lead to a shortage of red blood cells, white blood cells, and platelets, resulting in symptoms like fatigue, increased risk of infections, and easy bruising or bleeding. The exact cause of aplastic anemia can vary, but it may be triggered by factors such as autoimmune diseases, exposure to certain chemicals, or viral infections. Treatment options include blood transfusions, medications to stimulate blood cell production, or in severe cases, a bone marrow transplant.
