Clinical InformationClinical

  • Hemochromatosis

    a disorder of iron metabolism characterized by a triad of hemosiderosis; liver cirrhosis; and diabetes mellitus. it is caused by massive iron deposits in parenchymal cells that may develop after a prolonged increase of iron absorption. (jablonski's dictionary of syndromes & eponymic diseases, 2d ed)

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.
