Bariatric - Weight Loss Surgery

Gastric bypass and other types of weight-loss surgery — also called bariatric or metabolic surgery — involve making changes to your digestive system to help you lose weight. Bariatric surgery is done when diet and exercise haven't worked or when you have serious health problems because of your weight. Some weight-loss procedures limit how much you can eat. Others work by reducing the body's ability to absorb fat and calories. Some procedures do both. Also, you must make permanent healthy changes to your diet and get regular exercise to help ensure the long-term success of bariatric surgery.

Biliopancreatic diversion with duodenal switch (BPD/DS)

BPD/DS is generally done as a single procedure; however, in some circumstances, the procedure may be performed as two separate operations — sleeve gastrectomy followed by intestinal bypass once weight loss has begun. While a BPD/DS is very effective, it has risks, including malnutrition and vitamin deficiencies.
