Hereditary Hemochromatosis

In plain words: The body absorbs too much iron from food. Over years, extra iron can build up in organs. Regular blood removal (phlebotomy) is the main treatment.

Your genetics may influence your health, but they do not determine your worth. Understanding your body creates opportunities for informed care—not blame.

Designed to Heal provides general educational information and personal wellness tools. It does not diagnose genetic conditions, interpret genetic tests, or replace qualified medical care. Genetic disorders may require specialized diets, medication, monitoring, or other medical treatments. Consult a qualified healthcare professional before changing your treatment, nutrition, or exercise plan.

Emergency? Call 911 (U.S.) or your local emergency number. For a mental health crisis, call or text 988. Emergency Help

We do not diagnose, interpret genetic tests or calculate risk. For testing or family-planning questions, ask your clinician about a certified genetic counselor.

1. Overview

Hereditary hemochromatosis causes the body to absorb and store too much iron. Untreated, iron can collect in the liver, heart, pancreas and joints.

2. Genetic cause and inheritance

Most often caused by changes in the HFE gene and usually autosomal recessive. Many people with the gene changes never develop iron overload.

3. Symptoms and complications

  • Often none early on
  • Tiredness, joint pain, belly pain
  • Possible complications: liver disease, diabetes, heart problems, skin darkening

4. How clinicians diagnose it

Blood tests for iron levels (such as ferritin and transferrin saturation), genetic testing, and sometimes liver imaging.

5. Established medical treatment

  • Therapeutic phlebotomy — regularly removing blood — when your clinician says it's needed
  • Ongoing iron-level monitoring
  • Some people may be prescribed medication if phlebotomy isn't possible

6. Nutrition considerations

Dietary changes do not replace therapeutic phlebotomy when indicated. Clinicians commonly advise avoiding iron and vitamin C supplements and limiting alcohol. Avoid raw shellfish, which can carry bacteria that are dangerous with iron overload.

Nutrition, movement and other supportive practices may support overall health, but they cannot change the inherited genetic variant.

7. Activity considerations

There are no special activity limits for most people. Ask your clinician if you have heart or liver involvement.

8. Safety precautions

  • Don't take iron supplements or iron-fortified multivitamins unless advised
  • Avoid raw oysters and shellfish
  • Limit or avoid alcohol to protect the liver

9. Questions to ask your clinician

  • What are my ferritin and transferrin saturation targets?
  • How often will I need phlebotomy?
  • Should my brothers, sisters or children be tested?
