Ironing Out the Deficiency: Tracking Iron in Celiac Disease Before and After the Gluten-Free Diet
Abstract
Celiac disease (CeD) is a gluten-induced immune-mediated enteropathy that preferentially involves the proximal duodenum. Consequently, iron deficiency is common in CeD, impacting at least 10% of newly diagnosed individuals. In this narrative review, we aim to investigate the mechanisms, prevalence, treatment, and monitoring of iron deficiency and the impacts of a gluten-free diet (GFD) on iron deficiency in individuals with CeD. We will also review the role of and approach to iron supplementation in this population. Specifically, we will explore whether mucosal healing on a GFD is sufficient for the management of iron deficiency amongst individuals with CeD.
