Most loss of iron from the body is associated with loss of blood. Iron is primarily stored in the body's red blood cells, so when blood is lost, so is iron. Iron excretion through urine is minimal and excretion through bile is also relatively low, as most bile is reabsorbed in the intestines. When red blood cells die, the iron from the cells is recycled and used to make new red blood cells rather than being excreted.
