In clinical practice, all types of anemia are proliferative anemia except for aplastic anemia which is proliferative hypoplasia. Therefore, how to treat aplastic anemia needs to be based on the type of anemia. For example, in iron deficiency anemia, the most common method is oral iron treatment, such as iron dextran, iron sucrose, etc. Also, the cause of the anemia should be found and treated, such as iron deficiency anemia caused by hemorrhoids can be treated surgically, and if the iron deficiency anemia is caused by parasites, deworming treatment can be given. Proliferative anemia and megaloblastic anemia, which is caused by the lack of folic acid and vitamin B12, can be treated very well by oral folic acid or vitamin B12 injection. Hemolytic anemia can be treated with oral glucocorticoids or removal of the spleen. Good treatment effect can also be achieved.
