Diabetes can increase a patient's risk for the development of a pressure ulcer. Specifically, diabetic heel ulcers require an interprofessional approach that includes nutritional care provided by a dietitian. Assessment of malnutrition risk, along with a review of macro- and micronutrient deficiencies, assists the dietitian in determining the most appropriate intervention for a diabetic patient with a heel ulcer. Standardized nutrition recommendations exist for the management of pressure ulcers; however, a need exists for further evidence to support these guidelines. This case report presents a patient with a diabetic heel ulcer and explores evidence-based nutrition management.
