Official title
Feasibility, Efficacy, and Mechanisms of Surgical vs Medical Diabetes Treatment
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The escalating pandemics of obesity and type 2 diabetes mellitus (T2DM) are among the most significant contributors to morbidity and mortality worldwide. Roux-en-Y gastric bypass (RYGB) surgery causes profound weight loss and dramatically ameliorates T2DM through mechanisms beyond just weight loss, but its role in diabetes management and the nature of its weight-independent anti-diabetes effects are not well established because of a paucity of appropriate randomized trials, the execution of which is hindered by numerous obstacles. The investigators therefore propose a feasibility study to demonstrate our capacity to identify, recruit, randomize, and track outcomes for 40 adult Group Health members identified as having T2DM and a BMI between 30-40 kg/m2.
