Health condition
Genetic haemochromatosis
Genetic haemochromatosis causes the body to absorb too much iron, which slowly accumulates in the liver, joints, heart and pancreas - common in people of Northern European ancestry and very treatable when caught early.

Key facts
The essentials at a glance.
Which gene and test confirm it, who should be tested in the family, and which specialist to see.
-
Usually caused by two copies of the C282Y variant in the HFE gene, inherited from both parents
-
Diagnosis: raised ferritin and transferrin saturation, confirmed by HFE genotyping - no liver biopsy needed in most cases
-
First-degree relatives should be offered iron studies and genetic testing
-
Treatment is venesection (regular blood removal), which is simple and highly effective before organ damage occurs
Understanding the condition
What it is and what happens next.
What causes it, how it is confirmed, and the testing and specialist routes available in the UK.
What it is and how it presents
Haemochromatosis is often called the Celtic curse: around 1 in 8 people of Northern European descent carry one HFE variant, and those who inherit two can load iron for decades before symptoms appear. Early complaints are vague, fatigue, joint aches (classically the knuckles), low mood or low libido, so the condition is regularly missed until ferritin is checked. Untreated iron overload can cause cirrhosis, diabetes, heart problems and arthritis.
Testing, surveillance and specialist care
The diagnostic pathway is straightforward: transferrin saturation and ferritin, then HFE genotyping to confirm, with a FibroScan or MRI to assess iron and fibrosis where levels are high. A hepatologist oversees venesection until iron stores normalise, after which maintenance is a few sessions a year, and siblings and children are offered testing. NHS clinical genetics services carry some of the longest waits in the health service, often many months for a first appointment, whereas private genetic testing and a specialist review can typically be arranged within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a hepatologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder

Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any emergency symptoms.
Frequently asked
Common questions about Genetic haemochromatosis.
Quick, plain-English answers to what people ask us most.
-
What is genetic haemochromatosis?
Genetic haemochromatosis is a diagnosis used by clinicians to describe a specific pattern of symptoms or findings. It's usually confirmed after a proper assessment, since several conditions can look similar at first.
-
How do you catch genetic haemochromatosis?
Genetic haemochromatosis is caused by an infectious organism, and the route of transmission and risk factors depend on the specific pathogen involved. Your clinician can explain how it's usually acquired and whether any particular exposure, travel history or underlying vulnerability is relevant in your case.
-
How would I know if I have genetic haemochromatosis?
Symptoms of genetic haemochromatosis vary from person to person and can range from mild and easily missed to significant enough to affect daily life. Because overlapping conditions can produce similar symptoms, a clinical assessment is the most reliable way to confirm what's actually going on.
-
Is genetic haemochromatosis serious or dangerous?
Most cases of genetic haemochromatosis are manageable with appropriate care, though, like many conditions, it can occasionally lead to complications if left unassessed or untreated. Your clinician can give you a realistic sense of the risks based on your specific presentation.
-
Can genetic haemochromatosis spread to other people?
Whether genetic haemochromatosis can be passed on to others depends on the specific organism responsible and the stage of illness. Your clinician can advise on any precautions worth taking around family members, colleagues or close contacts.
-
Can genetic haemochromatosis be treated or prevented?
Genetic haemochromatosis can often be managed effectively, and in some cases prevented or reversed, with the right combination of lifestyle changes, medication or other targeted treatment. A specialist will tailor the approach to your circumstances rather than applying a one-size-fits-all plan.
-
What treatment options are available for genetic haemochromatosis?
Management of genetic haemochromatosis is individualised, ranging from conservative measures and monitoring through to more active medical or surgical treatment depending on how it's affecting you. A clear diagnosis is the first step towards choosing the right approach.
-
How long does genetic haemochromatosis last?
The outlook for genetic haemochromatosis varies widely depending on the underlying cause, how early it's diagnosed, and how it responds to treatment. Many people see significant improvement with appropriate care, and your specialist can give you a more personalised timeframe once they've reviewed your case.
-
What else could genetic haemochromatosis be mistaken for?
Because several conditions can share similar symptoms to genetic haemochromatosis, clinicians often consider a short list of possibilities before confirming a diagnosis. This is one of the main reasons a proper assessment, and sometimes targeted tests, matters more than relying on symptoms alone.
-
When should I see a doctor about genetic haemochromatosis, and how quickly can I be seen privately?
It's worth seeking medical advice if symptoms of genetic haemochromatosis are persistent, worsening, or affecting your daily life, rather than waiting for them to resolve on their own. NHS routine referrals for this kind of assessment can take anywhere from around 20 to 45+ weeks, whereas private consultants typically offer an appointment within about two weeks.
