Haemochromatosis, or GH (genetic haemochromatosis), is a genetic disorder causing the body to absorb an excessive amount of iron from the diet.

You will also come across the term hereditary haemochromatosis and may come across the US spelling as hemochromatosis, without the ‘a’. The meanings are the same.

As a result of the genetic condition, iron can build up in the body to toxic levels. This is termed iron overload and is potentially very damaging. Iron is deposited in various organs – mainly the liver, but also the pancreas, heart, endocrine glands, and joints.
