If you do not have any iron in your body you would very likely be dead. The most common disease or condition that people get from not having enough iron is anemia.

Iron is needed for the body's synthesis of hemoglobin molecules (as it is the central element in the Hgb molecule). In states of iron deficiency, not enough hemoglobin can be formed and iron-deficiency anemia develops. This results in reduced oxygen carrying capacity and subjective feelings of weakness and fatigue.If your body doesn't get enough iron it can start to shut down, but sometimes it will slowly help your body gain muscle.
