The Role of Gut Microbiota in Modulating Inflammation and Insulin Resistance in Type 2 Diabetes Mellitus: Implications for Complication Management.

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance and severe complications, including cardiovascular diseases, neuropathy, retinopathy, and nephropathy. This article examines the role of gut microbiota in modulating inflammation and insulin resistance in type 2 diabetes mellitus (T2DM), as well as its implications for managing complications associated with the disease. We analyzed published literature to elucidate mechanisms linking microbial dysbiosis, impaired gut barrier function, and chronic inflammation to glycemic control and T2DM complications. Key findings suggest that gut microbiota dysbiosis contributes to systemic inflammation and insulin resistance, thereby exacerbating the complications of type 2 diabetes mellitus (T2DM). Therapeutic strategies, such as probiotics, prebiotics, and fecal microbiota transplantation, promise to improve glycemic control and mitigate complications by restoring microbial balance. This review provides a comprehensive framework for understanding the role of the gut microbiota in type 2 diabetes mellitus (T2DM) and highlights potential therapeutic interventions to enhance the management of complications.
