Hemochromatosis
Hemochromatosis is a genetic disorder that causes the body to absorb and store too much iron, leading to a buildup of iron in the body’s tissues and organs, particularly in the liver, heart, and pancreas. There are two main types of hemochromatosis: primary hemochromatosis and secondary hemochromatosis.
Primary hemochromatosis is caused by a genetic mutation that affects the HFE gene, which regulates iron absorption in the body. Secondary hemochromatosis is caused by other underlying conditions such as chronic alcohol abuse, chronic liver disease, and blood transfusions.
Risk Factors
- Family history: hemochromatosis is caused by a genetic mutation, so individuals with a family history of the disorder are at a higher risk of developing it.
- Ethnicity: hemochromatosis is more common in individuals of Northern European descent, particularly people of Irish, Scottish, English, and Welsh ancestry.
- Gender: hemochromatosis is more common in men than in women because women lose iron through menstruation, pregnancy, and childbirth.
- Alcohol consumption: excessive alcohol consumption can increase the risk of developing hemochromatosis by increasing the amount of iron absorbed by the body and by damaging the liver.
- Chronic liver disease: chronic liver disease can lead to secondary hemochromatosis, which is caused by an underlying condition.
- Blood transfusions: individuals who have received multiple blood transfusions are at a higher risk of developing hemochromatosis, as each unit of transfused blood contains a significant amount of iron.
- Other genetic disorders: some genetic disorders such as thalassemia, anemia, and sideroblastic anemia can increase the iron level because of increased red blood cell breakdown.
Symptoms & Diagnosis
Symptoms include:
- Fatigue.
- Abdominal pain.
- Joint pain.
- Loss of sex drive.
- Bronze or gray-colored skin.
- It can also cause liver cirrhosis, liver cancer, diabetes, and heart disease.
Hemochromatosis is diagnosed through blood tests, imaging studies, liver biopsy and genetic testing.
Treatment
Treatment for hemochromatosis typically includes a low-iron diet, and phlebotomy, a procedure in which blood is regularly removed from the body to reduce the iron levels. Iron chelating therapy is also used to remove excess iron. In advanced cases, liver transplantation may be necessary. It is important to detect and treat hemochromatosis early, as untreated cases can lead to severe damage to the liver, heart, and other organs and can be fatal.
Complications
- Liver damage: hemochromatosis can cause cirrhosis of the liver, which is a condition in which the liver becomes scarred and cannot function properly. Cirrhosis can lead to liver failure, liver cancer, and death.
- Heart disease: hemochromatosis can also cause damage to the heart and increase the risk of heart failure, arrhythmias, and cardiomyopathy.
- Diabetes: hemochromatosis can also cause diabetes, which is a condition in which the body cannot properly regulate blood sugar levels.
- Pancreatitis: hemochromatosis can also cause inflammation of the pancreas, which can lead to chronic pain, digestive problems, and malnutrition.
- Skin pigmentation: hemochromatosis can cause a bronze or gray coloration of the skin, which is caused by the accumulation of iron in the skin’s pigment cells.
- Arthritis: hemochromatosis can cause joint pain and stiffness, particularly in the fingers, toes, and knees.
- Sexual dysfunction: hemochromatosis can cause impotence in men and decreased libido in both men and women.
- Chronic fatigue: hemochromatosis can cause fatigue and weakness, which can make it difficult to perform daily activities.
It is important for individuals with hemochromatosis to be regularly monitored by a specialist to detect and manage any complications that may arise.

Hemochromatosis cannot be cured, but it can be treated and managed. Early detection and treatment can prevent complications, and regular monitoring can help to detect and manage any complications that may arise.
Yes, hemochromatosis is inherited in an autosomal recessive manner, which means that an individual needs to inherit two copies of the abnormal gene, one from each parent, to develop the disease.
A low-iron diet can be helpful in reducing the amount of iron absorbed by the body, and avoiding certain supplements like Vitamin C can aid in the reducing absorption of iron.
Hemochromatosis can affect fertility in both men and women. In men, it can cause low sperm count, and in women, it can cause irregular menstrual cycles and difficulty getting pregnant.
