Surgical interventions, particularly bariatric surgeries like gastric bypass or sleeve gastrectomy, have shown significant improvement in type 2 diabetes mellitus (T2DM). These procedures not only aid in weight loss but also enhance insulin sensitivity and glucose metabolism. The mechanisms include altered gut hormone secretion, improved insulin signaling, and reduced systemic inflammation. Such metabolic surgeries are considered effective options for patients with T2DM, especially those who are obese and have difficulty managing their condition through traditional medical treatments alone.
