Hemochromatosis happens when too much iron builds up in the body. Your body needs iron to make hemoglobin, the part of your blood that carries oxygen to all of your cells. But when there is too much iron, it can damage the liver and heart and lead to other diseases, such as diabetes and arthritis.
Hemochromatosis can be treated to prevent serious problems. But without treatment, hemochromatosis will continue storing iron in the body. When iron levels are dangerously high, organ and tissue damage can happen.
The most common type of hemochromatosis runs in families. This is called hereditary or primary hemochromatosis. But people sometimes get it from having a lot of blood transfusions, certain blood problems, liver disease, or alcohol use disorder. This is called acquired or secondary hemochromatosis.
Men are more likely than women to have too much iron built up. Women get rid of extra iron through blood from their menstrual cycles and during pregnancy.
Symptoms often don't appear until a person is age 40 or older. This is because extra iron builds up slowly throughout the person's life. And symptoms appear after a certain amount of extra iron builds up.
The early symptoms are somewhat vague or subtle. So this disease is sometimes mistaken for another condition. Early symptoms include:
Your doctor will do a physical examination and ask about your medical history. If the doctor suspects hemochromatosis, you will have blood tests to see if you have too much iron in your body.
Most of the time hemochromatosis is caused by a gene that runs in families. It is an autosomal recessive disorder that can be passed to a child from the parents. Hemochromatosis can be found early with a blood test. If you have this disease, you may want to have your children tested to see if they have it. Other family members may also want to be tested. Talking to a genetic counsellor will help you decide whether genetic testing is a good idea for you and your family.
Most medical experts do not think it is helpful to screen for hemochromatosis in the general population using blood tests or genetic tests because hemochromatosis is not common. In the United States, the U.S. Preventive Services Task Force (USPSTF) does not recommend genetic screening for hemochromatosis in the general population.footnote 1 The general population includes people who do not have symptoms of hemochromatosis and who do not have a parent, brother, sister, or child with the disease.
Treatment for hemochromatosis includes:
Most people need treatment for the rest of their lives. But some people may not need further treatment if their iron levels return to normal and the hemochromatosis is clearly caused by another disease or by a treatment for another disease (such as blood transfusions).
Having hemochromatosis in your family doesn't mean that you will automatically get it. If you find out that you have inherited a gene that causes hemochromatosis, that means you are more likely to get hemochromatosis. Your doctor or a genetic counsellor can help you understand the results of a gene test. You might watch for symptoms so that if you do get hemochromatosis, you can get treatment as early as possible. Early treatment can reverse most symptoms and prevent future problems.
At home, you can take steps to make sure you are not getting too much iron in food or drinks.
