Facilitated Release of Endogenous Enterokines
- Conditions
- Diabetes Mellitus, Type 2
- Interventions
- Dietary Supplement: Electrolyte SolutionDietary Supplement: Mixed-Meal
- Registration Number
- NCT04215328
- Lead Sponsor
- University of Southern California
- Brief Summary
The overall objective is to develop therapy for obesity and diabetes that is as effective as gastric bypass surgery but without the cost and safety concerns.
- Detailed Description
Gastric bypass leads to rapid, sustained diabetes remission in the majority of patients who undergo this procedure and is also highly effective therapy for obesity. However, currently \<1% of medically-eligible patients undergo this or other bariatric operations due to cost and safety concerns. The approach is based on data suggesting that the benefit of gastric bypass is largely due to anatomical rearrangement of the intestine which leads to accelerated delivery of nutrients to the jejunum. This rerouting of nutrients stimulates the release of multiple neural, hormonal and enterokine responses that are associated with appetite suppression and improved glucose control. In this pilot proposal the question under investigation is whether repeated rapid delivery of a mixed meal directly to the jejunum can promote weight loss and glucose control.
