About Hemochromatosis (Iron Overload)
Hemochromatosis is a disorder in which the body accumulates excessive amounts of iron, leading to harmful levels. This condition can cause iron overload, which can damage various organs and tissues in the body, including the liver, heart, pancreas, endocrine glands, and joints.
Hemochromatosis is a genetic disorder that commonly diagnosed in individuals between the ages of 40 and 60, particularly those of northern European ancestry. It affects approximately 1 in 200 people in the United States.
Without proper treatment, hemochromatosis can have serious health consequences. The body normally regulates iron absorption from the diet, but in hemochromatosis, there is an excessive absorption of iron. It is important to seek medical attention for diagnosis and appropriate management.
The pathophysiologic cause of Hemochromatosis is the release of excessive iron into the body due to fragile red blood cells. This can be caused by genetic factors, such as having two copies of a faulty HFE gene, which is the main risk factor for hereditary Hemochromatosis.
Other non-modifiable risk factors which cannot be controlled or changed include:
- Family history: Having a parent, child, brother, or sister with Hemochromatosis increases the likelihood of having it.
- Ethnicity: People of Northern European descent have a higher risk of developing Hemochromatosis compared to other ethnicities.
On the other hand, modifiable risk factors for Hemochromatosis are related to individual habits and lifestyle. These include:
- Alcohol dependency
- Taking iron or vitamin C supplements
- Frequent blood transfusions
It is important to note that maintaining a healthy weight, being physically active, and eating a healthy diet are recommended to reduce the risk of Hemochromatosis. However, it is always best to consult with your healthcare professional for personalized advice.
The most common early symptoms of Hemochromatosis include:
- Fatigue and weakness
- Joint pain
- Weight loss
- Abdominal pain
- Changes in skin color
- Loss of libido
As the condition progresses or reaches higher severity, the following symptoms may occur:
- Indented shape in the nails (spoon-like curve)
- Diabetes
- Skin discoloration (in over 90% of people with Hemochromatosis)
- Joint disease (arthropathy)
- Changes in liver function (jaundice, abdominal pain, liver enlargement)
- Heart issues (arrhythmias, congestive heart failure)
- Changes in hormone function (reduced sex drive, erectile dysfunction, absence of menstrual periods, loss of body hair)
- Increased risk of certain infections and liver cancer
It is important to note that symptoms can vary between individuals and some people may not experience any symptoms at all. If you suspect you have Hemochromatosis or are experiencing any concerning symptoms, it is best to consult with a healthcare professional for an accurate diagnosis and appropriate management.
To diagnose Hemochromatosis, doctors commonly perform the following examinations, tests, and procedures:
- Medical history review: Your doctor will ask about your medical history, including any symptoms you may be experiencing.
- Physical examination: Your doctor will conduct a physical examination to look for signs of Hemochromatosis, such as pain, swelling, or abnormalities in the body.
- Blood tests: A series of blood tests called an iron panel test is usually performed. These tests measure the levels of iron and certain proteins in your blood. They include serum iron, serum ferritin, total iron binding capacity, hemoglobin, and transferrin.
- Genetic testing: Genetic testing can confirm a diagnosis of Hemochromatosis by checking for abnormalities or mutations in the HFE gene. It can also identify family members who may be at risk.
- Liver biopsy (if necessary): In some cases, a liver biopsy may be recommended to confirm iron overload and assess the severity of Hemochromatosis. This procedure involves removing a small sample of liver tissue for examination.
To determine the stage or severity of Hemochromatosis, additional examinations and tests may include:
- Liver function tests: These blood tests assess how well your liver is functioning.
- MRI: Magnetic Resonance Imaging (MRI) provides detailed images of your liver to evaluate iron overload and monitor potential damage.
It is important to consult with your healthcare professional for personalized advice and guidance regarding the specific examinations, tests, and procedures that are appropriate for your individual situation.
The goals of treatment for Hemochromatosis are to reduce the amount of iron in the body to normal levels and manage the condition to relieve symptoms and increase longevity. Here are the recommended treatments and how they work to achieve these goals:
- Phlebotomy (therapeutic phlebotomy): This is the most common and direct treatment for Hemochromatosis. It involves regularly removing about a pint of blood, which helps lower the body's iron stores. By removing excess iron through blood removal, iron levels in the body can gradually return to normal.
- Chelation therapy: This treatment is an alternative for individuals who cannot undergo phlebotomy due to certain health conditions. Chelation therapy involves using medication, either in pill form or through injections, that binds to excess iron and helps eliminate it from the body.
- Dietary changes: Making specific dietary modifications can also help manage Hemochromatosis. For example, consuming foods low in iron can help reduce iron intake. Additionally, avoiding vitamin C supplements, raw shellfish, and excessive alcohol use may be recommended as these can increase iron absorption.
It is important to note that these treatment options should be discussed with a healthcare professional before initiating them. They can provide personalized guidance based on individual circumstances.
