The incidence of diabetes has increased rapidly across the entire world in the last 2 decades. Accumulating evidence suggests that gut microbiota contribute to the pathogenesis of diabetes. Several studies have demonstrated that patients with diabetes are characterized by a moderate degree of gut microbial dysbiosis. ⋯ The compositional changes in the gut microbiota in type 2 and type 1 diabetes are also discussed. Moreover, we introduce the new findings of fecal transplantation, and use of probiotics and prebiotics as new treatment strategies for diabetes. Future research should be focused on defining the primary species of the gut microbiota and their exact roles in diabetes, potentially increasing the possibility of fecal transplants as a therapeutic strategy for diabetes.
