Abstract

Type 2 diabetes mellitus (T2DM), which is distinguished by increased glucose levels in the bloodstream, is a metabolic disease with a rapidly increasing incidence worldwide. Nevertheless, the etiology and characteristics of the mechanism of T2DM remain unclear. Recently, abundant evidence has indicated that the intestinal microbiota is crucially involved in the initiation and progression of T2DM. The gut microbiome, the largest microecosystem, engages in material and energy metabolism in the human body. In this review, we concentrated on the correlation between the gut flora and T2DM. Meanwhile, we summarized the pathogenesis involving the intestinal flora in T2DM, as well as therapeutic approaches aimed at modulating the gut microbiota for the management of T2DM. Through the analysis presented here, we draw attention to further exploration of these research directions.

Keywords: Microbial metabolites, Intestinal flora, Probiotics, Insulin resistance, Type 2 diabetes

Core Tip: In this review, we summarized the pathogenesis that intestinal flora is involved in type 2 diabetes mellitus (T2DM), as well as therapeutic approaches aimed at modulating the gut microbial for the management of T2DM.
