Gastric bypass surgery treatment helps a person to lose weight by changing how the stomach and small intestine handle the food he or she eats. After the surgery, the stomach will be smaller and the person will feel full with less food. The food they eat will no longer go into some parts of the stomach and small intestine that absorb food. Gastric bypass can be done in two ways. With open surgery, the surgeon makes a large surgical cut to open the belly. The bypass is done by working on the stomach, small intestine, and other organs. Another way to do this surgery is to use a tiny camera, called a laparoscope. This camera is placed inside the patient's belly. The surgery is called laparoscopy. The scope allows the surgeon to see inside the belly. Gastroenterologists have extensive training in the diagnosis and treatment of conditions that affect the oesophagus, stomach, small intestine, large intestine (colon), and biliary system (e.g., liver, pancreas, gallbladder, and bile ducts). Gastroenterology is a subspecialty of internal medicine. Laparoscopic gastric banding surgery is a procedure to help with weight loss. The surgeon places a band around the upper part of your stomach to create a small pouch to hold food. The band limits the amount of food you can eat by making you feel full after eating small amounts of food. Restrictive operations like gastric sleeve surgery make the stomach smaller and help people lose weight. With a smaller stomach, you will feel full a lot quicker than you are used to.
