Hereditary hemochromatosis (he-moe-kroe-muh-TOE-sis) causes your body to absorb too much iron from the food you eat. Excess iron is stored in your organs, especially your liver, heart and pancreas. Too much iron can lead to life-threatening conditions, such as liver disease, heart problems and diabetes.

The genes that cause hemochromatosis are inherited, but only a minority of people who have the genes ever develop serious problems. Signs and symptoms of hereditary hemochromatosis usually appear in midlife. Treatment includes regularly removing blood from your body. Because much of the body’s iron is contained in red blood cells, this treatment lowers iron levels.
