Iron overload disorders lead to excess iron deposition in the body, which can occur as a result of genetic or secondary causes. Genetic iron overload, referred to as hereditary hemochromatosis, may present as a common autosomal recessive mutation or as one of several uncommon mutations. Secondary iron overload may result from frequent blood transfusions, exogenous iron intake, or certain hematological diseases such as dyserythropoietic syndrome or chronic hemolytic anemia. Iron overload may be asymptomatic, or may present with significant diseases of the liver, heart, endocrine glands, joints, or other organs. If treated appropriately prior to end-organ damage, life expectancy has been shown to be similar compared to matched populations. Alongside clinical assessment, diagnostic studies involve blood tests, imaging, and in some cases liver biopsy. The mainstay of therapy is periodic phlebotomy, although oral chelation is an option for selected patients.
Purpose of reviewIron overload disorders such as hemochromatosis involve unregulated absorption of dietary iron, leading to excessive iron accumulation in multiple organs. Phlebotomy is the standard of care for removal of excess iron, but dietary modification is not standardized in practice. The purpose of this article is to help standardize hemochromatosis diet counseling based on commonly asked patient questions. Recent findingsThe clinical benefit regarding dietary modification in iron overload patients is limited due to lack of large clinical trials, but preliminary results are promising. Recent studies suggest diet modification could reduce iron burden in hemochromatosis patients resulting in less annual phlebotomy as supported through small patient studies, concepts of physiology, and animal studies. SummaryThis article is a guide for physicians to counsel hemochromatosis patients based on commonly asked questions such as foods to avoid, foods to consume, use of alcohol, and use of supplements. The goal of this guide is to help standardize hemochromatosis diet counseling to reduce phlebotomy amount in patients. Standardization of diet counseling could help facilitate future patient studies to analyze the clinical significance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
