Iron-deficiency anemia occurs because of a lack of the mineral iron in the body. Bone marrow in the center of the bone needs iron to make hemoglobin, the part of the red blood cell that transports oxygen to the body's organs. Without adequate iron, the body cannot produce enough hemoglobin for red blood cells. The result is iron-deficiency anemia. This type of anemia can be caused by:
Early symptoms of anemia might include a general sense of tiredness, or fatigue. A mild-to-moderate B-12 deficiency could also cause some shortness of breath, a feeling of nervousness and possibly diarrhea. deficiency is rare in healthy young people, but isn't uncommon for older people with poor diets. Some individuals with a mild deficiency might have no obvious symptoms, but because vitamin B-12 is essential for the production of new red blood cells, mild anemia may occur with a low intake of this vitamin.
