Bariatric surgery consists of several different types of surgery that is performed to help overweight and obese individuals lose the excess weight. When an individual becomes morbidly obese, surgery may be the only option. Some of these surgeries include gastric bypass surgery and the Lap-Band surgery. The purpose of these surgeries is to not only help the individual to lose weight but to also learn how to eat healthier and control proper portions when they are eating food.
