Hemochromatosis is a genetic metabolic disorder where a person absorbs too much iron and can result in dangerously high accumulation of iron in vital organs such as liver, heart, joints and brain which is a condition of iron overload. When iron overload presents in someone younger than the age of thirty, it is called Juvenile hemochromatosis (JH).
