Gastric bypass surgery is a weight-loss procedure where the stomach is divided to create a small pouch that is directly connected to the small intestine, bypassing most of the stomach and a portion of the intestine. This surgery is indicated for individuals with a BMI over 40 or a BMI over 35 with serious obesity-related conditions such as type 2 diabetes, high blood pressure, or sleep apnea. Gastric bypass is highly effective, with patients typically losing up to 70% of their excess body weight and experiencing significant improvements in obesity-related health issues. The surgery is performed using the da Vinci XI Surgical System, which allows for a minimally invasive approach with enhanced precision. However, unlike some other bariatric procedures, gastric bypass usually requires an overnight hospital stay for monitoring and recovery.
