Abstract

Type 2 diabetes mellitus (T2DM) is a multifactorial metabolic disorder described by chronic hyperglycemia, insulin resistance, as well as low-grade inflammation. Recent research highlights the vital role of the gut microbiota in the pathogenesis and progression of T2DM. Dysbiosis can impair intestinal barrier integrity, promote systemic inflammation, and contribute to insulin resistance and glucose metabolism dysfunction. This review article investigates the mechanisms by which probiotics interact with gut microbiota and host signaling pathways to impact the onset and complications of T2DM. Databases were searched, and related articles were added, to get a thorough overview of the relationship between probiotics and T2DM and its complications. Probiotics have appeared as potential modulators of the gut microbiome, capable of restoring microbial balance and strengthening intestinal barrier function. Probiotics can influence glucose homeostasis through their multifaceted effects on the gut microbiota and host metabolism. Through the production of beneficial metabolites, suppress α-glucosidase activity, enhance short-chain fatty acid (SCFA) levels, competitive inhibition of pathogenic bacteria, regulation of gut-derived neurotransmitters such as serotonin, improve intestinal, and immune functions, probiotics may alleviate key mechanisms involved in T2DM development and its complications.
