Medical illustration of Haemochromatosis: too much iron in the body

In simple terms

Why iron accumulates, the organs it damages, and how venesection prevents all of it.

What it is, in plain words

Haemochromatosis is an inherited disorder in which the intestine absorbs more iron than the body needs. There is no efficient way to excrete iron, so it deposits over decades in the liver, pancreas, heart, joints and pituitary gland, damaging them. Treatment is simple and, if started early, life expectancy is normal.

Signs to look out for

Persistent fatigue and joint pain, especially the second and third knuckles
Bronze or grey skin pigmentation
Abdominal pain and abnormal liver blood tests
Diabetes appearing without typical risk factors
Loss of libido, erectile dysfunction, irregular periods, heart rhythm problems

Why it happens

Most cases in people of Northern European descent are caused by two copies of the HFE C282Y variant. Symptoms appear later in women because menstruation removes iron, so diagnosis is often after menopause.

How doctors confirm it

Transferrin saturation above 45% and a raised ferritin prompt genetic testing. MRI measures liver iron non-invasively, and liver biopsy or elastography assesses fibrosis when ferritin is very high.

Treatments and solutions

Venesection: removing about 500 ml of blood weekly or fortnightly until ferritin falls to target, then maintenance a few times a year
Iron chelation for the minority who cannot tolerate venesection
Avoiding iron and vitamin C supplements and raw shellfish, and limiting alcohol strictly
Screening first-degree relatives, since early treatment prevents all organ damage
Monitoring for liver cancer in those who already have cirrhosis

Living with it day to day

Diet alone cannot control it, but simple habits help: tea with meals reduces absorption, and no iron-fortified supplements. Treatment does not reverse established cirrhosis or diabetes, which is why early diagnosis matters.

When to seek medical help

See a doctor for unexplained fatigue with joint pain and abnormal liver tests, or if a close relative has been diagnosed.
