OAGB, or One Anastomosis Gastric Bypass, is a surgical procedure designed to assist with weight loss by altering the anatomy of the digestive system. In OAGB, a small stomach pouch is created and connected directly to the small intestine through a single anastomosis (connection), bypassing a portion of the stomach and the first part of the small intestine. This reduces the amount of food a person can eat and the absorption of calories and nutrients, leading to weight loss. OAGB is considered a simpler and potentially safer alternative to traditional gastric bypass surgery and can improve conditions associated with obesity, such as type 2 diabetes and high blood pressure.
