Gastric bypass surgery reduces stomach size and reroutes the digestive tract to limit food intake and absorption. It helps patients achieve significant long-term weight loss and improves obesity-related conditions. Results are permanent but require strict lifestyle changes.
Gastric Bypass Surgery is a surgical bariatric procedure that creates a small stomach pouch and reroutes part of the small intestine. This reduces calorie absorption and helps patients lose substantial weight. It is considered the 'gold standard' of weight-loss surgery.
