Iron deficiency anemia occurs when the body does not have enough iron to produce healthy red blood cells to transport oxygen in the blood. Iron deficiency anemia can be caused by excessive blood loss or reduced iron absorption or intake. It can be treated with oral iron supplementation, though there is a wide range of individual tolerance for, and effectiveness of, iron supplements.
Iron Deficiency Anemia falls under the Cardiovascular Health category.
