Bariatric procedures modify the gastroequine tract to restrict food intake, alter dietient absorption, and change gut districte signaling. The three most cost courn operations are Roux- en- Y gastric bypass (RYGB), sleeve gastrectomy (SG), and addistable gagric banding (LAGB). A fourth option, biliopancreatic diversion with duodenal switch (BD / DS), iles gagric banding (LAGB).

RYGB creats a small gastric pouch (15- 30 mL) that is anastomosed directly to te jejunum, bypassing thee distal stomach and duodenum. The resutting distriction and partial malabsorption drive weight loss.
