Advances in the Assessment of Nutritional Status and Its Intervention in Patients with Diabetic Foot Ulcers

Diabetic foot ulcer (DFU) is a common complication in patients with diabetes mellitus caused by diabetic peripheral neuropathy (DPN) and peripheral arterial disease (PAD), and the prognosis of DFU is still poor, despite improvements in our understanding and treatment of this diabetic complication. Previous studies have found that more than half of DFU patients suffer from moderate or severe malnutrition; therefore, the assessment of the nutritional status of DFU patients and their interventions have become a widespread concern in the medical field. The purpose of this article is to describe the mechanism of malnutrition in DFU patients, the impact of malnutrition on the prognosis of DFU patients, the clinical value of nutritional interventions, and the tools for assessing nutrition-related risks in DFU patients
