14971 Hemochromatosis Iron Overload

Overview

Hemochromatosis is a condition in which your body absorbs and stores too much iron from the food you eat. Excess iron builds up in organs such as the liver, heart, and pancreas over time, and can damage them. It is sometimes called iron overload. With regular monitoring and treatment, most people can stay healthy.

Hemochromatosis is one of the most common inherited conditions in people of Northern European ancestry. Around 1 in 10 people carry one copy of the gene change, but only some of them build up harmful iron levels.

It most often affects people of Northern European descent. Men usually develop symptoms earlier and more severely than women, because women lose iron through menstruation and pregnancy. Symptoms usually start after age 40 in men and after menopause in women.

Symptoms

Common symptoms

• Feeling very tired or weak
• Joint pain, especially in the knuckles or knees
• Unexplained stomach pain
• A bronze or gray skin color, sometimes described as 'slate gray'
• Loss of sex drive or erectile problems
• Irregular blood sugar levels or diabetes
• Liver problems, such as an enlarged liver or abnormal liver tests

Symptoms in children

• Hemochromatosis due to the common inherited form is rarely diagnosed in children. When children develop iron overload, it is usually because of a different, rarer genetic condition or repeated blood transfusions. Symptoms may include delayed growth, unexplained tiredness, or liver problems.

Symptoms in older adults

• In older adults, symptoms may be more advanced and include breathlessness, swelling of the legs, confusion, or severe joint pain. Some symptoms can appear similar to normal aging, so they are easy to overlook.

Causes

Main causes

• Inherited gene changes that make the body absorb too much iron from food
• Rarely, repeated blood transfusions or certain types of anemia
• Very high iron intake, for example from unnecessary iron supplements

Risk factors

• Having a parent or sibling with hemochromatosis or known gene changes
• Being of Northern European ancestry
• Being male
• Drinking high amounts of alcohol, which can add extra stress on the liver
• Taking iron or vitamin C supplements without a medical need

When to see a doctor

See a doctor urgently if:

• If you have jaundice, dark urine, swelling in your belly or legs, or you feel confused, you should be seen the same day.
• If you have any of the emergency symptoms above, call your local emergency number now.

Book a routine appointment if:

• If you have persistent tiredness, joint pain, or a family history of hemochromatosis, make an appointment with your GP or healthcare provider.
• If you have a first-degree relative (parent, brother, sister, or child) with hemochromatosis, ask about being tested.

Diagnosis

Hemochromatosis is usually diagnosed with blood tests. Your healthcare provider will first check the amount of iron in your blood. If it is high, they may offer a genetic blood test to confirm a gene change.

Tests that may be done

• Iron studies: blood tests that measure the amount of iron in your blood and how well it is carried
• Serum ferritin: a blood test that shows how much iron is stored in your body
• Genetic test: a blood or saliva test for the common gene changes linked to hemochromatosis
• Liver function tests: blood tests that check how well your liver is working
• If needed, an MRI scan can measure iron in the liver without a biopsy

What to expect at your appointment

Your provider will explain each test and what it means. You may need to fast for a few hours before iron blood tests. If your iron levels are very high, they will talk to you about next steps, which usually include regular iron removal and monitoring. The process is routine and not something to fear.

Treatment

Treatment for hemochromatosis focuses on safely lowering the level of iron in your body and keeping it in a normal range. You will have regular checks to make sure iron levels stay stable and that no organs have been affected.

Self-care at home

• Do not take iron supplements unless your doctor specifically tells you to.
• Do not take high-dose vitamin C with meals, because it can increase iron absorption.
• Limit alcohol, especially if you have liver problems.
• Wear a medical alert bracelet or carry a card stating you have hemochromatosis, so emergency teams know to avoid iron treatment.
• Attend all follow-up appointments and blood tests.

Medical treatments

The most common treatment is therapeutic phlebotomy, which means removing a small amount of blood from a vein, similar to donating blood. This encourages the body to use stored iron to make new blood cells. It is repeated until iron levels are normal, then done less often to maintain them. For people who cannot have phlebotomy, there are medications called chelators that help remove extra iron. They are given by mouth or by injection, depending on the person's situation. Your healthcare team will choose the right approach for you.

When is surgery considered?

Surgery is rarely needed for hemochromatosis. In advanced liver failure from long-term iron overload, a liver transplant may be considered, and this decision is made by a specialist team.

Living with this condition

Living with hemochromatosis means building a routine around regular check-ups and, for most people, maintenance phlebotomy every few months. Between appointments, you can live much as you did before. Staying informed and keeping communication open with your care team makes the condition feel manageable.

Lifestyle tips

• Stay active with regular exercise that suits your energy and joints.
• Drink alcohol only in moderation, or avoid it if your liver is affected.
• Drink tea or coffee with meals, which can reduce iron absorption slightly.
• Avoid raw or undercooked shellfish if you have liver disease, because you are more vulnerable to certain infections.
• Get enough sleep and manage stress in healthy ways.

Diet and exercise

You usually do not need a highly restrictive diet, but moderation helps. Eat a balanced diet with normal amounts of iron. Avoid iron-fortified cereals and supplements unless advised by your doctor. Discuss specific foods with a dietitian, especially if you have liver damage. Regular exercise supports heart health, joint mobility, and general well-being.

Mental health and emotional wellbeing

A genetic diagnosis can feel overwhelming and may bring worry about future health. It can also feel frustrating to manage a lifelong condition. These feelings are normal. Talk to your healthcare provider if you feel anxious or low, and lean on friends and family for support.

Prevention

You cannot change the genes you inherit. However, early detection and treatment can prevent iron overload from damaging your organs. If you have a family member with hemochromatosis, getting tested early means you can take action before symptoms develop.

Vaccines

Because liver health is so important, ask your healthcare provider about vaccines that protect the liver, such as hepatitis A and hepatitis B vaccines.

Screening programmes

If a close family member has hemochromatosis, your doctor may recommend you be tested, even if you have no symptoms. This is sometimes called family screening. Routine population screening for everyone is not usually recommended.

Complications

If left untreated

• Liver damage, leading to scarring (cirrhosis) or liver failure
• Diabetes from iron collecting in the pancreas
• Heart problems, including an irregular heartbeat or heart failure
• Arthritis and long-standing joint pain
• Bronze or gray skin color
• Hormone problems, such as low thyroid or low sex hormone levels

Long-term outlook

The outlook for hemochromatosis is very good when it is found early and treated. Treatment brings iron levels back to normal and allows many people to live a full, ordinary life. If some organ damage has already happened, treatment can often stop it from getting worse, and many symptoms improve over time.
