Exploring Gut Microbiota and its Impact on the Pathogenesis of Type 2 Diabetes

Type 2 Diabetes Mellitus (T2DM) has emerged as a rapidly escalating global health crisis with significant implications for individual well-being and societal development. While advancements have been made in understanding the genetic and environmental factors contributing to T2DM, the role of social determinants, psychological stress, poor dietary habits, inadequate sleep, and sedentary lifestyles demand further exploration. Oxidative stress, which is central to the pathogenesis of diabetes, is driven by several metabolic pathways such as the AGE, polyol, hexosamine, protein kinase C, and glycolytic pathways. Emerging evidence suggests that an imbalance in gut microbiota may play a pivotal role in developing obesity, metabolic syndrome, and T2DM. Promising therapies, including probiotics such as Lactobacillus and Bifidobacterium, show the potential to restore microbial balance, alleviate disease severity, and prevent diabetes-associated complications like retinopathy, neuropathy, nephropathy, and cardiomyopathy. Addressing this growing epidemic requires an innovative, comprehensive approach that combines lifestyle modifications, environmental interventions, and microbiota-targeted strategies for effective T2DM prevention and management.
