Type 2 Diabetes Mellitus: An Overview of Pathophysiology, Current Management, and Future Prospective

Type 2 diabetes mellitus (T2DM) is a complex metabolic disorder characterized by insulin resistance and progressive β-cell dysfunction, affecting over 500 million adults worldwide. This review synthesizes current understanding of T2DM pathophysiology, detailing molecular mechanisms of insulin signaling impairment, lipid dysregulation, and the role of chronic inflammation. Global epidemiology trends are examined, highlighting rising prevalence in low- and middle-income countries and the socioeconomic drivers of disease burden. Comprehensive management strategies are evaluated, including lifestyle interventions, dietary patterns, pharmacotherapy with established agents (metformin, sulfonylureas, insulin) and emerging classes (GLP-1 receptor agonists, SGLT2 inhibitors). Advances in personalized medicine, continuous glucose monitoring, and digital health tools are discussed. Finally, future prospects for T2DM care are explored, encompassing novel therapeutics targeting β-cell preservation, gene-editing approaches, and gut microbiome modulation. By integrating pathophysiology, epidemiology, management, and future directions, this review provides a roadmap for optimizing T2DM prevention and treatment in the coming decade.
