Abstract
Impaired healing of diabetic wounds is one of the most important complications of diabetes, often leading to lower limb amputations and incurring significant economic and psychosocial costs. Unfortunately, there are currently no effective prevention or treatment strategies available. Recent research has reported that an imbalance in the gut microbiota, known as dysbiosis, was linked to the onset of type 2 diabetes, as well as the development and progression of diabetic complications. Indeed, the gut microbiota has emerged as a promising therapeutic approach for treating type 2 diabetes and related diseases. However, there is few of literatures specifically discussing the relationship between gut microbiota and diabetic wounds. This review aims to explore the potential role of the gut microbiota, especially probiotics, and its associated byproducts such as short chain fatty acids, bile acids, hydrogen sulfide, and tryptophan metabolites on wound healing to provide fresh insights and novel perspectives for the treatment of chronic wounds in diabetes.
