Patient EducationClinical

Hemochromatosis

Hemochromatosis is a disease in which too much iron builds up in your body. Your body needs iron but too much of it is toxic. If you have hemochromatosis, you absorb more iron than you need. Your body has no natural way to get rid of the extra iron. It stores it in body tissues, especially the liver, heart, and pancreas.
