Gastric bypass surgery is a type of bariatric surgery that can help patients lose significant amounts of weight when dieting and exercising haven’t worked. You might be a candidate for bariatric surgery if you have obesity, particularly if you also have obesity-related health problems. Like other types of bariatric surgery, gastric bypass requires significant lifestyle changes to achieve results. Consider talking to a bariatric surgeon to find out if it might be right for you.
Which Approach Is Used
Bariatric surgeries use two primary approaches to facilitate weight loss. The first is the restrictive approach, which means that the operation limits the total amount of food that the patient can eat. The second is the malabsorptive approach, which means that the body is less capable of absorbing calories from food. Gastric bypass surgery combines these two approaches. It also uses a third approach, known as the metabolic approach. This increases levels of certain gastrointestinal hormones to increase feelings of satiety.
What Happens During the Surgery
Gastric bypass surgery most often is done laparoscopically. After creating small incisions, the surgeon will insert specialized medical instruments and create a smaller stomach pouch from the stomach. The small stomach pouch, which is about the size of an egg, is connected to the esophagus. The larger stomach remains connected to the intestines. A stoma, or an opening, is created between the pouch and the intestine. Then, the bowels are attached together at a certain point. All of these changes result in an average weight loss of two to four pounds per week for about six to 12 months.
What to Expect After the Surgery
The anatomical changes made during the surgery means that, thanks to the new stomach pouch, the patient feels full quickly. The stoma slows the emptying of the stomach pouch, During digestion, the food bypasses a portion of the small intestine, which means that the body absorbs fewer calories overall.
