Pre-operative Intranasal Oxytocin for Enhancing Bariatric-induced Diabetes Remission

January 12, 2022 updated by: Soroka University Medical Center

Pre-operative Intranasal Oxytocin for Enhancing Bariatric-induced Diabetes remissionPre-operative Intranasal Oxytocin for Enhancing Bariatric-induced Diabetes Remission

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in obese adults with diabetes undergoing bariatric surgery. Subjects will be randomized to receive of intranasal oxytocin or placebo (8 units 3 times daily) for 8 weeks prior surgery. Study visits include screening to determine eligibility, CGM will be connected before and after oxytocin administration, and 1 year post surgery. blood tests including oral glucose tolerance test will be done and fat samples will be taken during surgery. The investigator's hypothesis is that oxytocin administration prior bariatric surgery can induce diabetes remission in patients with diabetes
