A Comprehensive Analysis of Diabetic Complications and Advances in Management Strategies.

Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), is a pervasive chronic disease that affects millions of people worldwide. It predisposes individuals to a range of severe microvascular and macrovascular complications, which drastically impact the patient's quality of life and increase mortality rates owing to various comorbidities. This extensive review explores the intricate pathophysiology underlying diabetic complications, focusing on key mechanisms, such as atherosclerosis, insulin resistance, chronic inflammation, and endothelial dysfunction. It also highlights recent therapeutic advancements, including the introduction of SGLT2 inhibitors and GLP-1 receptor agonists, which provide benefits beyond glycemic control and offer cardiovascular and renal protection. Furthermore, the future position of SGLT2 inhibitors and GLP-1 receptor agonists in terms of the prevention of diabetes and macrovascular diseases will be discussed. Considering the differences in insulin secretion capacity between Western and Asian patients, including Japanese patients, we propose a treatment strategy for high-quality diabetes in Japan.
