The numerous surgical options available today can be grouped into two categories based on their weight loss mechanism. Gastric restrictive procedures include vertical banded gastroplasty (VBG), adjustable gastric banding (AGB), and Roux-en-Y gastric bypass (RYGB). The procedures causing malabsorption include biliopancreatic diversion (BPD) and biliopancreatic diversion with duodenal switch (BPD-DS). All of the procedures have been successful in improving comorbidities associated with obesity.

The most commonly performed procedure is RYGB because it has the best short- and long-term results for safety, efficacy, and durability, and it has been shown to be superior to AGB. RYBG is generally performed laparoscopically. All of the procedures require long-term dietary compliance and careful nutritional follow-up. [24]

A National Institutes of Health (NIH) consensus statement addresses the issue of surgical treatment for obesity and obesity with associated comorbid conditions. According to these guidelines, patients who are recommended for surgical treatment include those with a body mass index greater than 40 kg/m2, as well as patients with a body mass index greater than 35 kg/m2 and an obesity-related comorbid condition (including OHS).
