Laparoscopic Gastric Bypass
Laparoscopic gastric bypass, also known as Roux-en-Y gastric bypass (RYGB), is normally considered a golden standard for weight loss surgery. It works by limiting the amount of food consumption by reducing food absorption in the digestive system. A small pouch similar in size to the flexible gastric band limits food intake.
Furthermore, food absorption in the digestive system is limited by exempting most duodenum, upper intestine, and stomach from coming into contact with food. This is done by directly directing food from the pouch into the small intestine. Doctors often perform gastric bypass laparoscopically through incisions. They also recommend the procedure if other methods to lose weight, including exercise and dieting, are not effective.
