Inflammatory bowel disease (IBD) can cause micronutrient deficiencies that have cutaneous manifestations. Dermatologists may be the first to identify an undiagnosed micronutrient deficiency in the affected population. The approach to monitoring and repleting a micronutrient deficiency may be impacted by factors such as IBD activity and potential interactions between supplements and medications used to treat IBD. In this article, we review the most common micronutrient deficiencies observed in patients with IBD and their associated cutaneous manifestations. We also provide guidance for monitoring and supplementing each micronutrient discussed.
