Hemochromatosis is a genetic disorder that is characterized by the excessive accumulation of iron in the body. The body needs iron to function properly, but too much iron can be toxic and lead to a range of health problems.
Hemochromatosis is most commonly caused by a mutation in the HFE gene, which affects the body’s ability to regulate iron absorption. Hemochromatosis is often referred to as “iron overload” and can lead to serious life-threatening complications.
Symptoms of Hemochromatosis
The symptoms of hemochromatosis can be vague and can vary widely depending on the stage of the disease and the severity of iron overload. Some common symptoms of hemochromatosis include:.
- Fatigue and weakness
- Joint pain
- Abdominal pain and swelling
- Loss of sex drive or impotence
- Irregular periods or absent menstruation
- Depression or anxiety
- Memory loss or confusion
- Diabetes or high blood sugar levels
- Liver disease or liver failure
Not everyone with hemochromatosis will experience all of these symptoms, and some people with hemochromatosis may not experience any symptoms at all.
If you have any of these symptoms, you should talk to your doctor about getting tested for hemochromatosis.
Diagnosing Hemochromatosis
The diagnosis of hemochromatosis can be challenging because the symptoms can be vague and may not appear until later stages of the disease. Hemochromatosis is typically diagnosed using a combination of blood tests, imaging tests, and genetic testing.
A blood test to measure serum ferritin levels is often used as the first step in diagnosing hemochromatosis. Ferritin is a protein that stores iron, and high levels of ferritin in the blood can indicate excess iron in the body.
A blood test may also be used to measure transferrin saturation, which is the percentage of transferrin (a protein that carries iron in the blood) that is saturated with iron. A transferrin saturation level of 45% or higher is considered a sign of hemochromatosis.
If blood tests suggest hemochromatosis, your doctor may order imaging tests such as an abdominal ultrasound or MRI to evaluate the liver and other organs for signs of iron overload.
A liver biopsy may also be necessary to confirm the diagnosis and assess the extent of liver damage.
Genetic testing may also be used to confirm a diagnosis of hemochromatosis. Testing for the HFE gene mutation is typically done with a blood sample or a cheek swab.
If a mutation is detected, other family members may be tested to determine if they are also at risk for the disorder.

Treating Hemochromatosis
The treatment for hemochromatosis is aimed at reducing levels of iron in the body to prevent organ damage and other complications.
The most common treatment for hemochromatosis is phlebotomy, which involves the removal of blood from the body on a regular basis. This allows the body to eliminate excess iron, and over time, iron levels can be reduced to a safe level.
Phlebotomy is typically performed once a week or once every other week until iron levels are within a normal range. After that, phlebotomy may be done less frequently to maintain normal iron levels.
The duration of phlebotomy treatment depends on the severity of iron overload and the presence of complications such as liver disease or diabetes.
In some cases, iron chelation therapy may be used to treat hemochromatosis. Iron chelation therapy involves the use of medications that bind to excess iron in the body and help remove it in the urine or feces.
This type of therapy is typically reserved for people who cannot tolerate phlebotomy or who have complications such as heart failure.
Preventing Hemochromatosis
Because hemochromatosis is a genetic disorder, it cannot be prevented. However, early diagnosis and treatment can prevent complications and improve outcomes.
If you have a family history of hemochromatosis or have symptoms of iron overload, talk to your doctor about getting tested.
If you have hemochromatosis, you can take steps to manage your condition and reduce the risk of complications.
This may include following a low-iron diet, avoiding supplements that contain iron, and limiting alcohol intake, which can increase the absorption of iron in the body.
Conclusion
Understanding the symptoms and diagnosis of hemochromatosis is important for early detection and effective treatment.
If you have a family history of hemochromatosis or are experiencing symptoms of iron overload, talk to your doctor about getting tested. Early detection and treatment can improve outcomes and prevent complications.
