Official title
Autonomic Nervous System Function and Novel Determinants of Glucose Homeostasis Following Bariatric Surgery
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In the proposed study, the investigators will explore three specific aims. First, the investigators will examine cross-sectionally the association of obesity on sympathetic, parasympathetic, and sympathetic/ parasympathetic nerve fiber balance. In addition, the investigators will determine the relationship of the ANS and osteocalcin. Osteocalcin will be measured before and after a mixed meal tolerance test. In the second specific aim, the investigators will prospectively follow-up these individuals (n=30) following bariatric surgery. The effect of weight loss on measures of the ANS and osteocalcin will be examined 6 months following surgery with participants serving as their own control, pre- and post-surgical intervention. Thirdly, the investigators will address whether the effect of weight loss on the ANS and osteocalcin differ between those who had a history of diabetes at baseline versus those with no history of diabetes.
