Genetic haemochromatosis (GH) is the most common inherited genetic disorder in caucasians, affecting approximately 1 in every 200–250 people. It leads to an increased absorption and deposition of iron, and if it is untreated it can cause systemic iron overload in some patients. This iron overload can cause inflammation and tissue damage to multiple organs, with the potential to lead to heart disease, diabetes and cirrhosis of the liver. Despite being a common condition, it is thought to be under diagnosed. This article will discuss the signs and symptoms of this hereditary condition, as well as methods of treatment.
