The procedure is performed under general anesthesia. During the procedure, the surgeon narrows the stomach into a thin vertical sleeve, about the size and shape of a banana. The remainder of the stomach is removed. This is mostly a restrictive operation, but there is a small metabolic component to the procedure as well.  The patient’s smaller stomach gets full quickly after eating smaller portions of food, so the patient is satisfied after consuming less calories. Digestion and absorption of nutrients are very seldomly impaired. **Gastric bypass surgery** for weight lossis performed under general anesthesia. The surgeon divides the stomach into a small upper section and a larger bottom section. The top section of the stomach is where eaten food goes, and since it is connected to the small intestine, the stomach, duodenum and first portion of the jejunum are bypassed and thus cannot absorb nutrients as they usually do. This procedure is both restrictive because the stomach is made smaller, and malabsortive because the bypassed segment of the gastrointestinal tract cannot absorb any nutrients. Patients feel satiated although they are eating and absorbing less food. Patients must take vitamins and other nutrients. ## Meet the Surgeon ## [![Bariatrics_Dr. Perrone_Landing Page](https://pages.saintpetershcs.com/hs-fs/hubfs/Bariatrics_Dr.%20Perrone_Landing%20Page.png?width=900&height=473&name=Bariatrics_Dr.%20Perrone_Landing%20Page.png)](https://www.saintpetershcs.com/services/bariatric-surgery/meet-dr-john-perrone) ## Saint Peter’s Weight Loss and Bariatric Center 254 Easton Ave. New Brunswick NJ 08901 732-745-8555   ### Follow Us on Social Media ### Subscribe to Our Newsletter Subscribe to the Saint Peter's Better Health newsletter and receive the latest health news, community events, recipes, and more. ### Give to Saint Peter's Proceeds generated are used to provide assistance for the many capital and operating needs of Saint Peter's University Hospital.
