Gastric bypass, or Roux-en-Y gastric bypass, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine. This procedure is done to bypass a significant part of the stomach and the first section of the small intestine, reducing the amount of food intake and the absorption of nutrients, leading to weight loss.
Success Rate: The success rate of gastric bypass surgery is high, with about 80% of patients achieving and maintaining significant weight loss.
Recovery: The hospital stay after gastric bypass is usually 2 to 3 days. Full recovery, including the ability to resume normal physical activities, may take 2 to 3 weeks.
