Hereditary Hemochromatosis
What is Hereditary Hemochromatosis?
Hereditary hemochromatosis is a genetic condition that causes your body to absorb too much iron from food. Iron is essential for making red blood cells and carrying oxygen. But when iron builds up over years, it deposits in organs like your liver, heart, pancreas, and joints. This excess iron damages tissue and can lead to serious complications.
Most people with hereditary hemochromatosis inherit two copies of a mutated gene, one from each parent. This autosomal recessive pattern means both parents carry the gene but may not have symptoms themselves. The condition is one of the most common genetic disorders among people of Northern European descent.
The good news is that hereditary hemochromatosis is highly treatable when caught early. Regular blood tests can detect iron overload before organs sustain damage. Early treatment prevents complications and allows people with this condition to live normal, healthy lives.
Symptoms
- Fatigue and weakness that doesn't improve with rest
- Joint pain, especially in the hands and knuckles
- Abdominal pain or discomfort
- Loss of sex drive or erectile dysfunction
- Irregular or absent menstrual periods in women
- Bronze or gray skin color
- Memory problems or brain fog
- Unexplained weight loss
- Liver enlargement or tenderness
- Heart palpitations or irregular heartbeat
Many people have no symptoms in the early stages of hereditary hemochromatosis. Iron builds up slowly over decades, often without noticeable signs. Symptoms typically appear in men between ages 40 and 60 and in women after menopause. Women often develop symptoms later because menstruation naturally removes iron from the body. This is why blood testing is critical for early detection, especially if you have a family history.

Causes and risk factors
Hereditary hemochromatosis is caused by mutations in genes that control how much iron your body absorbs from food. The most common mutation occurs in the HFE gene. When you inherit two copies of this mutated gene, your intestines absorb two to three times more iron than normal. Your body has no natural way to remove excess iron, so it accumulates in organs over time.
Risk factors include Northern European ancestry, being male, and having a family history of the condition. Men develop iron overload earlier because women lose iron through menstruation and pregnancy. Age also matters, as iron accumulation takes decades. People who drink alcohol heavily face higher risk of liver damage from iron deposits. Vitamin C supplements can increase iron absorption and worsen overload in people with this condition.
How it's diagnosed
Hereditary hemochromatosis is diagnosed through blood tests that measure iron levels in your body. Serum iron shows how much iron is circulating in your blood. Transferrin saturation measures the percentage of iron-binding proteins that are carrying iron. A transferrin saturation above 45 percent is a key screening marker for this condition. In people with hereditary hemochromatosis, transferrin saturation often rises to 60 to 80 percent or higher, typically before other symptoms appear.
Rite Aid offers testing for serum iron and transferrin saturation as part of our flagship health panel. These tests can detect iron overload early, before organ damage occurs. If screening tests show elevated levels, your doctor may order genetic testing to confirm the HFE gene mutation. They may also check ferritin levels to assess how much iron is stored in your body. Some people need liver imaging or biopsy to evaluate organ damage.
Treatment options
- Phlebotomy, or therapeutic blood removal, to reduce iron levels
- Initial treatment involves removing one pint of blood once or twice weekly
- Maintenance phlebotomy every two to four months once levels normalize
- Limit iron-rich foods like red meat and iron-fortified cereals
- Avoid vitamin C supplements, which increase iron absorption
- Avoid alcohol to protect your liver from additional damage
- Limit raw shellfish due to infection risk with high iron levels
- Regular monitoring of iron levels, liver function, and organ health
- Chelation therapy in rare cases when phlebotomy is not possible
- Genetic counseling for family members who may carry the gene

Frequently asked questions
Hereditary hemochromatosis is a specific genetic condition that causes your body to absorb too much iron from food. Iron overload is a broader term that describes any situation where excess iron accumulates in the body. Hereditary hemochromatosis is the most common cause of iron overload, but other conditions like repeated blood transfusions or certain anemias can also cause it.
Yes, you can have hereditary hemochromatosis even if your parents show no symptoms. This condition follows an autosomal recessive pattern, meaning you need two copies of the mutated gene to develop iron overload. Your parents may each carry one copy of the gene without having symptoms themselves. When both parents are carriers, each child has a 25 percent chance of inheriting both copies.
Testing frequency depends on your treatment stage. During initial phlebotomy treatment, you may need blood tests every one to two weeks to monitor progress. Once your iron levels normalize, testing every three to six months is typical during maintenance therapy. Your doctor will adjust the schedule based on your transferrin saturation and ferritin levels.
Most people with hereditary hemochromatosis need ongoing phlebotomy for life, but the frequency decreases significantly over time. Initial treatment requires weekly or twice-weekly blood removal until iron levels normalize, which may take several months to a year. After that, maintenance phlebotomy every two to four months is usually enough to keep iron levels in a healthy range.
Diet changes alone cannot treat hereditary hemochromatosis, but they play an important supporting role. Avoiding iron-rich foods and vitamin C supplements can slow iron accumulation. However, phlebotomy is the only proven treatment that effectively removes excess iron from the body. Think of diet modifications as helpful additions to medical treatment, not replacements for it.
Untreated hereditary hemochromatosis can cause serious organ damage as iron deposits accumulate over decades. Common complications include cirrhosis and liver cancer, diabetes from pancreatic damage, heart failure and arrhythmias, and severe arthritis. Early detection and treatment prevent these complications entirely. This is why screening is so important, especially if you have a family history.
Yes, hereditary hemochromatosis is most common among people of Northern European descent, particularly those with Irish, Scottish, or Scandinavian ancestry. About one in 200 to 300 people of Northern European descent have the condition. It is much less common in people of Asian, African, or Hispanic backgrounds.
Yes, women with hereditary hemochromatosis can have healthy pregnancies with proper management. Pregnancy actually helps lower iron levels because the developing baby uses maternal iron and blood loss during delivery removes additional iron. After pregnancy, women typically resume phlebotomy treatment. Genetic counseling can help assess the risk of passing the condition to children.
Women develop symptoms of hereditary hemochromatosis later because menstruation naturally removes iron from the body each month. This regular blood loss prevents iron from accumulating as quickly as it does in men. After menopause, when periods stop, iron begins to build up more rapidly. This is why women often develop symptoms in their 50s or 60s, while men typically show symptoms in their 40s or 50s.
Yes, your first-degree relatives, including parents, siblings, and children, should get tested. They have a higher risk of carrying the gene mutations or having the condition themselves. Simple blood tests for serum iron and transferrin saturation can screen for early signs. If those tests are abnormal, genetic testing can confirm whether they have the HFE gene mutations.
