Anemias are classified by etiology. The causes include:

•Blood loss

•Deficient erythropoiesis

•Excessive hemolysis

Blood Loss

Anemias can result from acute or chronic blood loss. Identification of the cause of the blood loss and resolution of the loss will most likely resolve the anemia. The lost erythrocyte mass and hemoglobin content will be replaced via transfusion or erythropoiesis (Blackwell, 2001).
