Anemia is a lower than normal number of red blood cells (erythrocytes) in the blood, usually measured by a decrease in the amount of hemoglobin. Hemoglobin is the red pigment in red blood cells that transports oxygen. There are many types and potential causes of anemia. For information about a specific type of anemia, see one of the following articles: Anemia - B12 deficiency Anemia - folate deficiency Anemia - iron deficiency Anemia due to chronic disease Hemolytic anemia Hemolytic anemia - G-6-PD deficiency Idiopathic aplastic anemia Idiopathic autoimmune hemolytic anemia Immune hemolytic anemia Immune hemolytic anemia - drug-induced Megaloblastic anemia Pernicious anemia Secondary aplastic anemia Sickle cell anemia
