Bariatric Resection is a weight loss procedure meant to help overweight and obese people shed pounds and keep them off. It is also known as weight loss surgery, or bariatric surgery for short. Weight loss surgery has become a popular alternative to diet and exercise for people who are struggling with their weight. While it has helped some people lose weight and change their eating habits, others have found the procedure to be risky, invasive, and expensive. There are a few different types of bariatric surgery. Your doctor will determine which one is right for you depending on your weight, your overall health, and your goals.
The most common weight loss surgery is gastric bypass. In this procedure, your small intestine is divided into two sections. Food then bypasses your stomach, which shrinks to about the size of an egg. This reduces the amount of food you can eat at one time, so you feel full faster. The food then moves directly to your small intestine, which absorbs fewer calories.
In vertical sleeve gastrectomy or VSG, part of the stomach is removed, leaving a narrow tube that is about an inch long. The new stomach area produces a hormone that helps limit hunger and slows digestion.« Back to Glossary Index
