Managing haemochromatosis: diet and treatment

Too much iron in the body can lead to serious health complications over time. Learn how a tailored haemochromatosis diet, iron reduction strategies and specialist treatment may help manage iron overload safely.

Hereditary haemochromatosis is one of the most common genetic conditions affecting iron regulation in Australia. The condition causes the body to absorb more dietary iron than it needs, increasing iron stores over time and potentially damaging organs if left untreated.

Haemochromatosis is a condition where the body absorbs and stores too much iron. In people with hereditary haemochromatosis, the body cannot properly regulate iron absorption, leading to excess iron accumulation over time. This iron overload may affect the liver, pancreas, heart, joints and other organs if left untreated.

Iron is an essential nutrient that helps your body produce haemoglobin, which carries oxygen through the bloodstream. However, excess iron can be harmful when the body stores more than it needs.

A carefully managed haemochromatosis diet may help reduce iron absorption and support healthy iron levels alongside ongoing treatment.

High iron levels are most commonly caused by hereditary haemochromatosis, where inherited genetic changes increase iron absorption from food.

However, elevated iron stores may also occur due to:

• Repeated blood transfusions
• Excessive iron supplementation
• Chronic liver disease
• Some metabolic conditions
• Certain blood disorders
• Alcohol-related liver disease

Many people are first diagnosed after abnormal iron studies or elevated ferritin levels are identified during routine blood testing.

Symptoms of haemochromatosis often develop gradually and may vary depending on iron levels and organ involvement.

• Common symptoms may include:
• Ongoing fatigue
• Joint pain
• Abdominal discomfort
• Brain fog or mood changes
• Reduced libido
• Irregular periods
• Bronze or grey skin pigmentation
• Elevated liver enzymes
• Unexplained liver abnormalities
• Weakness or reduced exercise tolerance

Many symptoms of iron overload are nonspecific and may overlap with those of other conditions. Some people may not develop noticeable symptoms until significant iron accumulation has already occurred.

While scans cannot diagnose hereditary haemochromatosis itself, liver scanning may help assess whether excess iron has affected the liver.

At Moonee Valley Specialist Centre, FibroScan® technology may be used to assess liver stiffness and identify possible liver damage associated with iron overload.

FibroScan is a non-invasive liver scan that provides fast results without surgery or hospital admission. It may help support:

• Early liver disease detection
• Ongoing liver monitoring
• Treatment planning
• Assessment of fibrosis or fatty liver disease

Treatment aims to lower iron stores before complications develop. Management depends on iron levels, symptoms and whether organ damage has occurred.

Venesection

Venesection involves removing blood regularly to lower iron stores. The process is similar to donating blood and remains one of the most common treatments for hereditary haemochromatosis.

Some people may initially require weekly venesection until ferritin levels stabilise.

Chelation therapy

Chelation therapy uses medication that binds excess iron, allowing it to be removed from the body. This treatment is typically used in specific situations where venesection may not be suitable.

Ongoing monitoring

Regular blood tests help monitor ferritin levels, transferrin saturation and treatment progress over time. Ongoing monitoring may also help identify early signs of liver damage or other complications.

How to lower iron levels effectively

Reducing iron overload usually requires a combination of medical treatment, monitoring and practical lifestyle strategies.

Helpful approaches may include:

• Following specialist treatment recommendations
• Attending regular blood testing
• Avoiding unnecessary iron supplements
• Limiting excess alcohol intake
• Managing red meat intake
• Avoiding high-dose vitamin C supplements unless medically advised
• Supporting liver health through diet and lifestyle

Diet alone is usually not enough to treat haemochromatosis. Ongoing medical management is often required.

A haemochromatosis diet focuses on reducing iron absorption while maintaining balanced nutrition.

The goal is not to completely eliminate iron-containing foods unless specifically advised by a specialist. Instead, dietary changes aim to reduce excessive iron absorption and support long-term management.

Foods to eat to lower iron levels

Some foods may help reduce iron absorption when eaten alongside iron-rich foods.

These may include:

• Tea and coffee
• Dairy products
• Whole foods rich in calcium
• Plant-based foods that contain only non-heme iron

While diet alone cannot treat haemochromatosis, practical diet tips may help lower iron absorption and support ongoing treatment.

The goal is not to create a low-iron diet unless specifically advised by your doctor. Instead, dietary changes aim to decrease iron absorption and help reduce iron levels safely over time.

Foods to avoid with haemochromatosis

People with haemochromatosis may be advised to limit iron-rich foods that are high in heme iron absorption, including:

• Red meat
• Liver and offal
• Iron-fortified or enriched foods
• Some processed breakfast cereals

This does not mean completely avoiding foods that contain iron. Instead, the goal is to limit the amount of iron the body absorbs while maintaining a healthy diet.

What reduces iron absorption?

Certain nutrients and dietary combinations may reduce the amount of iron the body absorbs.

Potential iron absorption inhibitors include:

• Calcium
• Tea polyphenols
• Coffee compounds
• Some fibre-rich foods

Vitamin C may increase iron absorption, particularly when consumed alongside iron-rich foods.

Protecting liver health is an important part of managing haemochromatosis, particularly when iron overload affects liver tissue.

Helpful liver health strategies may include:

• Maintaining a balanced diet
• Reducing excess alcohol intake
• Managing weight and metabolic health
• Monitoring liver function regularly
• Following specialist recommendations
• Addressing fatty liver disease where relevant

People with haemochromatosis may also benefit from ongoing liver monitoring, particularly if ferritin levels remain elevated.

Iron overload does not usually cause damage overnight. In many people, excess iron builds slowly over several years before complications become noticeable. Without diagnosis and treatment, stored iron may gradually affect major organs, including the liver, pancreas, heart and joints.

The liver is often one of the first organs affected. Ongoing iron accumulation may contribute to inflammation, fatty liver disease, fibrosis or cirrhosis over time. Some people may also develop diabetes, hormonal changes, chronic fatigue, heart problems or worsening joint pain as iron levels continue to rise.

The good news is that many complications associated with haemochromatosis may be reduced or slowed with early diagnosis, regular monitoring and appropriate treatment.

Managing haemochromatosis is usually an ongoing process rather than a once-off treatment. Long-term care focuses on keeping iron levels within a safer range while monitoring for signs of organ stress or liver damage.

Regular blood tests are often used to track ferritin levels and transferrin saturation over time. Many patients also benefit from ongoing liver assessment, particularly if iron levels have remained elevated for an extended period.

Lifestyle factors may also play an important role. Reducing excess alcohol intake, avoiding unnecessary iron supplementation and following a balanced diet may help support liver health and reduce additional strain on the body.

Attending follow-up appointments and continuing specialist care, even after iron levels improve, may help support long-term health outcomes and reduce the risk of future complications.

Some people with haemochromatosis have no obvious symptoms in the early stages. Others may experience vague or ongoing health changes that are easy to overlook.

It may be worth speaking with your GP or specialist if you have persistent fatigue, abnormal iron studies, elevated ferritin levels or unexplained liver test abnormalities. Joint pain, digestive symptoms and a family history of haemochromatosis may also warrant further investigation.

Early assessment may help identify iron overload before significant organ damage develops, particularly in people with inherited risk factors or ongoing liver concerns.

What causes haemochromatosis?

Haemochromatosis is usually caused by inherited gene mutations that affect how the body regulates iron absorption. In hereditary haemochromatosis, the body absorbs more iron than it needs, leading to excess iron accumulation over time.

What foods should people with haemochromatosis avoid?

People with haemochromatosis may be advised to limit foods high in iron, including red meat, liver, offal, and iron-fortified products. It may also be helpful to avoid excessive alcohol and unnecessary iron supplements.

Foods rich in iron do not always need to be eliminated completely, but managing iron intake may help reduce iron overload alongside medical treatment.

Does vitamin C increase iron absorption?

Yes. Iron and vitamin C consumed together may enhance iron absorption, particularly from iron-rich foods. For this reason, many people with haemochromatosis are advised to avoid vitamin C supplements unless their doctor recommends them.

However, fruits and vegetables containing vitamin C remain important as part of a varied diet and usually have only a small effect on iron levels when consumed normally.

Can diet alone treat haemochromatosis?

No. A haemochromatosis diet may help manage iron intake and support healthy iron levels, but diet alone is usually not enough to treat iron overload.

Medical treatments for haemochromatosis, including venesection and ongoing blood monitoring, are commonly required to safely lower total iron stores.

Can haemochromatosis cause iron deficiency anaemia?

Haemochromatosis and iron deficiency anaemia are different conditions. However, iron levels can occasionally become too low during treatment if iron is removed too aggressively.

This is why regular blood tests and specialist monitoring are important for persons with iron overload receiving treatment.
