Anemia.Description of Anemia

Anemia occurs when blood does not have enough red blood cells or when the blood does not have enough hemoglobin. Hemoglobin is the oxygen-carrying pigment found in red blood cells. Anemia can be life-threatening.
Although there are over 400 different forms of anemia, this health profile will only address the three most common: iron-deficiency anemia, vitamin B12 anemia and folic acid deficiency.
Anemias can also be caused by such conditions as external bleeding, chronic disease, pregnancy, alcoholism, bleeding disorders, infection and hereditary conditions.
