Purpose of review The purpose of this review is to present recent data that defines our current understanding of the role of the gut microbiome in the development of T2DM.

Recent findings Recent studies focus on the physiology and molecular pathways of the gut microbiome–host interaction. Short-chain fatty acids (SCFAs) derived from the fermentation of plant-based nonsoluble fiber bind to G-protein-coupled receptors (GPR) GPR 41 and GPR 43 to induce enteroendocrine molecules that control appetite, and to upregulate intestinal gluconeogenesis gene expression that controls glucose regulation. “Metabolic endotexemia” reflects a state of low-grade systemic inflammation that results from lipopolysaccharide (LPS) release from the gut into the systemic circulation in response to a high-fat diet. Inflammatory pathways induced by LPS, activation of toll-like receptor-4 (TLR-4), and other inflammatory signaling pathways are mediators of systemic inflammation, insulin resistance and type II diabetes mellitus.

Summary Recent scientific data support that derangements in the composition of the microbiota, termed “microbiome dysbiosis” is a factor in the development of “metabolic endotoxemia” and T2DM. Therapeutic options that target the gut microbiome in the treatment of T2DM are explored.
