A bariatric surgeon is a medical professional who has expertise in performing four types of bariatric surgeries, i.e. Adjustable gastric banding (AGB), Roux-en-Y gastric bypass (RYGB), Biliopancreatic diversion with a duodenal switch (BPD-DS) and Vertical sleeve gastrectomy (VSG). Today, most bariatric surgeries are laparoscopic because when compared with open surgery, it requires less extensive cuts, causes relatively minimal tissue damage, leads to fewer post-operative complications and allows for earlier hospital discharge. A bariatric surgeon is often called a laparoscopic surgeon.
The combination of exercise and diet sometimes fail to effectively treat people with extreme and excessive obesity. Bariatric surgery (weight-loss surgery) is an operation that is performed in order to help such individuals lose weight. Bariatric surgery may lower death rates for patients with severe obesity, especially when coupled with healthy eating and lifestyle changes after surgery.
