Advances in bariatric surgery have significantly improved the treatment of severe obesity; procedures such as gastric bypass, sleeve gastrectomy, and gastric banding have been shown to have substantial long-term benefits with respect to weight loss and metabolic health. These surgeries not only help reduce weight but also improve comorbidities like type 2 diabetes, hypertension, and sleep apnea. Newer techniques, such as minimally invasive procedures and endoscopic bariatric interventions, have further reduced risks and recovery times, expanding access to surgical treatments. The latest developments that have been made in bariatric surgery can be shown at the International Obesity and Metabolism Conference: experts come together to discuss up-to-date techniques, results, and the role surgery is increasingly playing in dealing with obesity and preventing metabolic diseases.
