Hemochromatosis is a rare disorder of the iron metabolism, which leads to abnormal deposits of iron in the liver and other organs. Alone in Germany, an estimated two to four hundred thousand people suffer from hemochromatosis.
Hence, the so-called iron overload is among the most common hereditary disorders. In the format of this short communication we will discuss, what the characteristics of hemochromatosis are and how it can be recognized at an early stage. The disorder is usually diagnosed in patients between 40 and 60 years old. Primary hemochromatosis has a hereditary cause, whereas the secondary form of iron overload occurs with blood disorders. Patients suffer from a particular form of diabetes mellitus and dark pigmentation of the skin (bronzing), as well as hepatic cirrhosis. Other clinical syndromes include hormonal imbalances, cardiomyopathy and other physiological changes. Patients show elevated serum levels of iron and increased concentrations of ferritin. Routine treatment consists in phlebotomies. Moreover, extreme challenges such as food items rich in iron must be avoided. An iron-reduced diet, however, cannot replace phlebotomies as a form of therapy.

Zusammenfassung der Kapitel (Chapter Summaries)
Hemochromatosis: When the liver stores too much iron: This introductory chapter defines hemochromatosis as a rare iron metabolism disorder causing iron deposits in the liver and other organs. It highlights the prevalence of the disorder, typical age of diagnosis (40-60 years), and differentiates between primary (hereditary) and secondary forms. The chapter introduces key symptoms such as diabetes mellitus, skin pigmentation, hepatic cirrhosis, and hormonal imbalances, along with elevated serum iron and ferritin levels. The standard treatment—phlebotomy—and the necessity of avoiding iron-rich foods are also mentioned, emphasizing that dietary changes alone are insufficient.
Hemochromatosis (iron overload): This section delves deeper into the genetic basis of hemochromatosis, explaining its autosomal recessive inheritance pattern and the significantly higher incidence in men. It discusses the dramatic increase in total body iron content from the normal 4-5g to as much as 80g due to increased intestinal absorption. The chapter outlines the delayed onset of symptoms (often after age 20, more commonly between 40-60) and the impact on women, particularly post-menopause. The consequences of untreated hemochromatosis, including fatigue, joint problems, diabetes, skin pigmentation abnormalities, cardiomyopathy, hormonal disorders, hepatic cirrhosis, and even liver cancer, are detailed, emphasizing the crucial role of timely diagnosis and phlebotomy treatment for maintaining life expectancy and quality of life.
Iron overload – Hemochromatosis: This chapter reinforces the prevalence of hemochromatosis as a common hereditary metabolic disorder, highlighting the significant number of affected individuals and potential carriers within the population. The text explains the genetic defect's impact on increased iron absorption in the small intestine and subsequent deposition in various organs. The chapter details a range of symptoms—fatigue, abdominal cramping, heart irregularities, joint pain, libido issues, and skin discoloration—and discusses the potential long-term consequences of untreated iron overload, such as hepatic cirrhosis, diabetes, hormonal disorders, heart problems, and increased liver cancer risk. Diagnostic methods, including iron saturation and ferritin levels, genetic testing, and liver biopsy, are described, along with the primary treatment: lifelong phlebotomy or, if contraindicated, Desferoxamine medication. The importance of a low-iron diet as a supportive measure, though not a standalone therapy, is also emphasized.
Eat and drink right with hemochromatosis: This chapter addresses the dietary management of hemochromatosis, clarifying that while it's not a diet-induced condition, a balanced, low-iron diet is beneficial, particularly in conjunction with phlebotomy. It emphasizes avoiding iron-rich foods, especially meat and sausage products, and cautions against multivitamin/mineral supplements containing iron. The chapter explores how vitamin C enhances iron absorption, while substances like tannin (in black tea), calcium (in dairy), and dietary fiber (pectin, phytate) can hinder it. The recommendation for an iron-reduced, healthy, and diversified diet is reiterated, along with the potential benefit of zinc supplements for blocking iron uptake.

Frequently Asked Questions: Hemochromatosis - A Medical-Nutritional Overview
What is Hemochromatosis?
Hemochromatosis is a rare genetic disorder characterized by the body's inability to regulate iron absorption, leading to an excessive buildup of iron in the liver and other organs. This iron overload can cause serious health problems if left untreated.
What are the different types of Hemochromatosis?
The text primarily focuses on primary (hereditary) hemochromatosis, caused by a genetic defect. Secondary hemochromatosis can occur due to other medical conditions or excessive iron intake.
Who is affected by Hemochromatosis?
Hemochromatosis is more common in men and typically manifests between the ages of 40 and 60. However, symptoms can appear later or earlier in life. The text highlights the significant number of potential carriers within the population.
What are the symptoms of Hemochromatosis?
Symptoms can vary but often include fatigue, joint pain, abdominal pain, skin pigmentation changes (bronzing), diabetes, heart problems, and hormonal imbalances. In advanced stages, liver cirrhosis and liver cancer can develop.
How is Hemochromatosis diagnosed?
Diagnosis involves blood tests to measure serum iron levels and ferritin (an iron storage protein), genetic testing (often focusing on the HFE gene), and potentially a liver biopsy. Elevated iron saturation and ferritin levels are key indicators.
How is Hemochromatosis treated?
The primary treatment is phlebotomy (regular blood removal) to reduce iron levels. In some cases, medication such as Desferoxamine may be used. Dietary modifications, focusing on reducing iron intake, are crucial as a supportive measure.
What dietary changes are recommended for Hemochromatosis?
A low-iron diet is essential. This involves limiting iron-rich foods like red meat, organ meats, and iron-fortified foods. The text advises against excessive vitamin C intake as it enhances iron absorption. Foods with tannin, calcium, and fiber can help hinder iron absorption.
Is dietary change alone sufficient to treat Hemochromatosis?
No. Dietary modifications are a crucial supportive measure, but they are not a standalone treatment. Phlebotomy remains the primary therapy to effectively manage iron overload.
What are the long-term health implications of untreated Hemochromatosis?
Untreated hemochromatosis can lead to severe complications such as liver cirrhosis, liver failure, diabetes, heart disease, hormonal disorders, and an increased risk of liver cancer, significantly impacting life expectancy and quality of life.
What is the role of genetics in Hemochromatosis?
Hemochromatosis is primarily an autosomal recessive disorder. A genetic defect, most commonly in the HFE gene, causes increased intestinal iron absorption and subsequent iron overload.
Where can I find more information about Hemochromatosis?
Consult with a medical professional for further information and personalized guidance. They can provide accurate diagnosis, appropriate treatment, and ongoing health management.
