By Sam
Hereditary Haemochromatosis (HFE): Causes, Symptoms, Diagnosis, and Treatment Complete article to Iron Overload Disorder | Symptoms, Genetics, Testing, and Management Hereditary Haemochromatosis (HFE) is one of the most common genetic disorders affecting iron metabolism in the human body. Despite its prevalence, it remains widely underdiagnosed due to its slow progression and non-specific early symptoms. This condition leads to excessive absorption and accumulation of iron in vital organs such as the liver, heart, pancreas, joints, and skin. Over time, this excess iron can cause serious and potentially life-threatening complications. In this comprehensive article, we will explore what Hereditary Haemochromatosis is, how it develops, its genetic basis, symptoms, diagnostic methods, treatment options, lifestyle modifications, and long-term outlook.
