Genetic hemochromatosis is a condition caused by excessive iron absorption in the intestines, leading to high levels of iron in the body's tissues and organs. If untreated, it can damage organs like the liver, heart, and pancreas. The main treatment is regular phlebotomy to reduce iron levels in the body. Dietary changes and medication may also be used to manage iron overload and related organ damage. It is often inherited in an autosomal recessive pattern and associated with mutations in the HFE gene.
