This document summarizes research on the resolution of metabolic syndrome and morbid obesity through bariatric surgery procedures like Roux-en-Y gastric bypass and biliopancreatic diversion. Studies have found that both procedures effectively result in weight loss and normalization of blood glucose, lipids, blood pressure, and other metabolic markers in the majority of patients. Specifically, Roux-en-Y gastric bypass has been shown to improve markers of metabolic syndrome through changes in gastrointestinal hormones, while biliopancreatic diversion aims to limit fat and starch absorption.
