Could you tell me what happens if you become anemic?

See your doctor: Anemia never represents a final diagnosis. Either you are losing blood (for example, in menstrual flow or in the stool) or you are not making enough red blood cells in your bone marrow (you may have a blood disorder or not enough iron or vitamin intake) or your body is destroying your red blood cells. The specific reason for your being anemic must be determined. See your doctor asap.
