Bariatric surgery is an operation that is performed in order to treat people with extreme and excessive obesity among those exercises and diet alone fails to lose weight. Bariatric surgery may lower death rates for patients with severe obesity, especially when coupled with healthy eating and lifestyle changes after surgery.
Types of Surgeries
There are various types of bariatric surgeries that can be performed. Surgery may involve cutting open the abdomen or by means of laparoscopy, during which surgical instruments are guided into the abdomen through small half-inch incisions. Today, most bariatric surgery is laparoscopic because it requires less extensive cuts, causes relatively minimal tissue damage, leads to lesser post-operative complications and minimizes hospital stay.
There are four types of operations that are offered:
- Adjustable gastric banding (AGB)
- Roux-en-Y gastric bypass (RYGB)
- Biliopancreatic diversion with a duodenal switch (BPD-DS)
- Vertical sleeve gastrectomy (VSG)
