Micrograph of a liver biopsy showing iron deposits due to iron overload. Iron stain. | |
Specialty | Hematology, gastroenterology |
Symptoms | Tiredness, abdominal pain, darkening skin, sexual dysfunction [2] |
Complications | Cirrhosis, liver failure, liver cancer, heart failure, diabetes, arthritis, infections [2] [1] |
Usual onset | Males > 40, females > 50 [2] |
Types | Primary, secondary [1] |
Causes | Primary:
Hereditary haemochromatosis (HHC)

Risk factors | Liver diseases, alcoholism [2] |
Diagnostic method | Blood tests (high ratio of iron to transferrin), liver biopsy [2] |
Treatment | Phlebotomy, chelation therapy, liver transplant [2] |

Iron overload, also known as hemochromatosis, is the build up of excessive iron in the body. [1] Symptoms may include tiredness, abdominal pain, darkening skin, and sexual dysfunction. [2] Complications may include cirrhosis, liver failure, liver cancer, heart failure, diabetes, arthritis, and infections. [2] [1]
The most common causes are hereditary haemochromatosis (HHC), a genetic disorder, and iron overload from repeated blood transfusions. [2] Rarely it may occur due excessive dietary intake or liver injury during early development (the latter known as neonatal hemochromatosis). [2] Risk factors for more severe disease include other liver diseases and alcoholism. [2] Diagnosis is generally by blood tests, which may be supported by a liver biopsy. [2]
Most cases of iron overload due to HCC are treated with the regular removal of blood by phlebotomy. [2] Initially this may be done twice per week and once levels come down may occur two to three times per year. [2] Those who have iron overload due to other reasons may be treated with chelation therapy. [2] Neonatal hemochromatosis may be treated with exchange transfusions and IVIG. [2] Occasionally a liver transplant is required. [2] Iron supplements and vitamin C should be avoided. [2]
About 1 in 400 white people have HHC and it is the most common autosomal recessive disorder in this group. [1] Onset of symptoms in males is usually after the age of 40 and in females after the age of 50. [2] While males and females are equally likely to carry the mutation, males are 2 to 3 times likely to develop complications. [2] [1] Outcomes in HHC are good if the disease is detected early and treated. [1] The symptoms of iron overload were first described by Armand Trousseau in 1865, though it was not until 1889 that von Recklinghausen linked the disease to iron. [3]
