Haemochromatosis is a genetic disorder characterized by excessive absorption and accumulation of iron in the body. This condition causes the body to absorb more iron from the diet than it needs, leading to its storage in various organs, particularly the liver, heart, pancreas, and joints.
The primary form of haemochromatosis, known as hereditary haemochromatosis, is caused by mutations in the HFE gene, which regulates the absorption of dietary iron in the small intestine. These mutations disrupt the body’s ability to regulate iron absorption, resulting in the gradual buildup of iron over time.
Symptoms of haemochromatosis often don’t appear until later stages when iron levels have significantly accumulated. These symptoms may include fatigue, joint pain, abdominal pain, weakness, and in more severe cases, organ damage leading to conditions like cirrhosis, diabetes, or heart problems.
Diagnosis of haemochromatosis involves blood tests that measure serum ferritin levels, transferrin saturation, and genetic testing to detect mutations in the HFE gene. Early detection is crucial to prevent complications associated with excessive iron accumulation.
Treatment for haemochromatosis typically involves therapeutic phlebotomy, a procedure similar to blood donation, where excess iron is removed by regularly drawing blood. Managing iron levels through phlebotomy helps prevent organ damage and reduces the risk of complications. Additionally, dietary changes to reduce iron intake and regular monitoring of iron levels are part of managing this condition.
While haemochromatosis is not curable, early detection, prompt treatment, and ongoing management through therapeutic phlebotomy can effectively control iron levels, prevent complications, and allow individuals to lead relatively healthy lives. Close monitoring and proper medical care play a vital role in managing this disorder and minimizing its impact on overall health.

Do you want to know more about haemochromatosis? Let’s take a look at these 21 interesting facts about haemochromatosis.
- Genetic Basis: Haemochromatosis is primarily an inherited disorder caused by mutations in the HFE gene, impacting iron absorption.
- Common Hereditary Disorder: It is one of the most common genetic disorders in people of European descent.
- Excess Iron Absorption: Haemochromatosis leads to the excessive absorption of dietary iron, resulting in its accumulation in various organs.
- Liver Impact: Iron accumulation in the liver can lead to cirrhosis, an irreversible condition affecting liver function.
- Cardiac Complications: Excessive iron in the heart can cause cardiomyopathy, potentially leading to heart failure.
- Joint Problems: Accumulated iron in joints can result in arthritis and joint pain.
- Symptom Variability: Symptoms of haemochromatosis can vary widely among individuals, with some experiencing few or no symptoms while others face severe complications.
- Fatigue: Chronic fatigue is a common symptom due to iron overload impacting overall health.
- Skin Discoloration: In advanced cases, skin may appear bronze or gray due to excess iron deposition.
- Delayed Onset: Symptoms may not manifest until middle age or later when iron accumulation reaches critical levels.
- Men are More Affected: Men are more likely to exhibit symptoms due to iron build-up occurring over time.
- Women After Menopause: Women may develop symptoms post-menopause when they stop losing iron through menstruation.
- Diagnostic Tests: Diagnosis involves blood tests measuring serum ferritin, transferrin saturation, and genetic testing for HFE mutations.
- Treatment with Phlebotomy: Regular therapeutic phlebotomy, akin to blood donation, is the primary treatment to reduce iron levels.
- Iron Chelation Therapy: In cases where phlebotomy is not suitable, iron chelation drugs can help remove excess iron.
- Dietary Modifications: A low-iron diet, avoiding iron-rich foods and supplements, can assist in managing iron levels.
- Screening for Family Members: Family members of individuals with haemochromatosis are often encouraged to undergo genetic testing due to the hereditary nature of the condition.
- Prevalence: Haemochromatosis prevalence varies among populations, with higher rates observed in individuals with Celtic, Northern European, or Scandinavian ancestry.
- Increased Risk of Certain Conditions: People with haemochromatosis have an elevated risk of developing diabetes, arthritis, liver diseases, and heart conditions.
- Quality of Life Improvement: Early detection and treatment can significantly improve the quality and length of life for individuals with haemochromatosis.
- Awareness and Education: Raising awareness and educating both healthcare professionals and the public about haemochromatosis are crucial in early detection and management.
Haemochromatosis, a genetic condition leading to iron overload, underscores the intricate balance of iron regulation in the body. Its silent accumulation over time poses a significant health risk, impacting multiple organs and functions. However, the story of haemochromatosis also encompasses hope, as early detection and management strategies empower individuals to navigate this condition effectively. Through genetic screenings, awareness initiatives, and advancements in treatment, lives are transformed, complications are averted, and individuals affected by haemochromatosis can lead fulfilling lives.
