Iron is required to make hemoglobin, which carries oxygen inside the blood cells. Without sufficient amounts of iron, the production of red blood cells decreases. Iron deficient anemia may be caused by the lack of iron in the diet, or by blood loss cause due to injury, gastrointestinal bleeding, or heavy menstrual bleeding.
