Iron toxicity is a condition caused the overingestion of iron, usually in the form of supplements. Metallic iron and rust are not soluble in water and rarely cause iron toxicity if ingested. However, dietary forms of iron are metabolized far more quickly in the stomach and can quickly overload the body's organs. Death is usually from liver failure. Initially, the iron attacks the lining of the stomach, resulting in pain, nausea and vomiting. These symptoms disappear quickly as the iron is digested, but then the iron tends to accumulate in the brain and liver. See also Hemochromatosis.
