Anemia for the Primary Care Physician.

Abstract

Anemia denotes a reduced red blood cell (RBC) mass from any cause. The causes of anemia are numerous and due to decreased (or abnormal) erythropoesis, shortened RBC life span, or blood loss. The most common etiology of anemia is iron deficiency. A judicious work up of anemia includes evaluating the reticulocyte count and peripheral smear. The severity of illness of a patient with anemia is determined by the degree of anemia and the seriousness of the underlying disorder. Management of patients with hereditary and hemolytic anemias should involve a hematologist.
