'Haemochromatosis with diabetes mellitus'

A condition in which one has an unusual amount of iron in one's body is called haemochromatosis. This condition can be caused by one's diet or can be hereditary.

For haemochromatosis (a inherited disorder that results in excess iron in the blood) and polycythaemia (malignant disorder (as in polycythaemia rubra vera) resulting in excess red blood cells).

Essentially to remove components from the blood that cannot be removed/treated with medication

The human body processing excess iron is known as haemochromatosis. One symptom is when iron leaks for the vein into the blood which is then absorbed to organs and tissue. Skins as a tissue shows the results in darken skin spots.
