Haemochromatosis is an inherited condition where iron levels in the body slowly build up over many years.
This build-up of iron, known as iron overload, can cause unpleasant symptoms. If it is not treated, this can damage parts of the body such as the liver, joints, pancreas and heart.
Haemochromatosis most often affects people of white northern European background and is particularly common in countries where lots of people have a Celtic background, such as Ireland, Scotland and Wales.

Extra fact: More than 10 million Americans are carriers of one mutation of the CF gene.
