About

This study will determine how two variants of gastric bypass induce changes in dynamic endocrine response in the fasting and post-prandial state, both before and at different time points after the surgical interventions. This study will monitor the endocrine dynamics after different anatomical modifications produced by Roux-en-Y gastric bypass procedures in diabetic participants and normoglycemic participants, to gain insights into the mechanisms beyond the metabolic improvement after the two surgical variants through participants re-evaluation at different time points.

Full description

Abstract Obesity prevalence is a major risk factor for the onset of type 2 diabetes. Diabetic patients are frequently overweight or obese and diabetes complications are the main cause of obesity-related morbimortality, demanding proper and effective clinical management. Bariatric surgery, originally conceived for obesity treatment, has proven not only to be the most effective weight loss intervention but also for comorbidity management, with a strong impact on type 2 diabetes. As the antidiabetic effects of bariatric surgery largely exceed the metabolic improvement predicted by the caloric restriction and weight loss, which are mostly driven by the enteroendocrine response, this challenges the academic and medical communities with the need to learn how to leverage the enteroendocrine system to achieve glucose homeostasis. Supported on the investigators' previous work focusing on gastro-intestinal hormones and glucose metabolism after bariatric surgery, the investigators now aim to monitor the intestinal hormone after different anatomical modifications produced by Roux-en-Y gastric bypass procedures in diabetic participants and normoglycemic individuals. The utmost goal will be to unravel the endocrine mechanisms beyond the metabolic improvement observed after the surgical manipulations, towards the identification of novel targets for hormone based treatments in an individualised clinical approach. Study Overview: Participants in this study will be submitted to either short or long BPL RYGB surgery. Participants visits will be scheduled before surgery and after surgery at 3, 6 and 12 months for detailed participants assessment that will include anthropometric and biochemical evaluation and the performance of a MMTT with plasma sampling for hormonal profiles. Participant Enrolment: Participants will be selected from the cohort of patients referred for multidisciplinary evaluation by the clinical team for surgical treatment of obesity of the Centro Hospitalar Entre Douro e Vouga (CHEDV). Participants found to be suitable according to the entry criteria and accept to participate will be enrolled in the study and assigned to one of the three study groups according to participants clinical features.
