Gastric bypass is a surgical procedure that reduces the size of the stomach and reroutes food away from most of the small intestine. This makes it difficult to eat large amounts of food and helps to promote weight loss.
Gastric bypass is typically suitable for individuals who are severely obese and have failed to lose weight through diet and exercise. It is also a good option for individuals with certain medical conditions, such as diabetes and sleep apnea, that are related to obesity.
