Gastric bypass (Roux-en-Y) is a two-part procedure that first creates a small stomach pouch (about the size of an egg), then connects it directly to the small intestine, bypassing most of the stomach and part of the digestive tract. This restricts food intake and reduces calorie absorption. Performed laparoscopically in most cases, it offers both restrictive and malabsorptive mechanisms for weight loss. Patients typically lose 60-80% of excess weight within 12-18 months post-surgery.
