Longitudinal Phenotyping of Bariatric Surgery Patients

Imperial College London·observational·Posted Apr 20, 2015·Updated Nov 6, 2020

In Brief

An observational study evaluating Laparoscopic Roux-en-Y Gastric Bypass and Laparoscopic Sleeve Gastrectomy for Obesity and Diabetes Mellitus, Type 2. Completed, enrolled 158 participants across 1 site.

Detailed Summary

Recent studies have shown that bacteria within the gut play an important role in diabetes improvement after bariatric (weight-loss) surgery. Bariatric surgery fundamentally changes the environment within the gut, which results in changes to the makeup of the trillions of bacteria living within it. These changes in the gut bacteria can affect the body in a number of complex ways, which we are only just beginning to understand. For example, gut bacteria breakdown food we are unable to absorb ourselves, leading to altered sugar levels and can release molecules that act to reduce appetite. In this study we aim to find out how bariatric surgery changes the gut bacteria and how this leads to weight loss and improvement of diabetes. With this understanding we hope to discover potential targets for future treatments, such as identifying beneficial bacteria that could be supplemented with probiotics in patients. Additionally, although highly successful, up to 30% of obese patients do not undergo improvement of their diabetes after bariatric surgery. We aim to identify molecules within the patient's blood or urine that are able to predict the likely chance a patient will undergo improvement in their diabetes after bariatric surgery to help clinicians select patients most likely to benefit.
