Aplastic anemia is divided into two types: acute aplastic anemia and chronic aplastic anemia.

Acute aplastic anemia presents suddenly and is severe. Treatment requires intensified immunotherapy or suppression of hematopoietic stem cell transplantation. Chronic aplastic anemia develops slowly, has a longer history, and is relatively less severe. The treatment for chronic aplastic anemia mainly involves immunotherapy combined with therapy to promote hematopoiesis.

In addition, regardless of the type, all cases of aplastic anemia require regular complete blood count checks and, when necessary, supportive treatment with red blood cell and platelet transfusions.
