Effects of Sleeve Gastrectomy on Calcium Metabolism and the Skeleton

NCT02778490 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 60

Last updated 2022-10-28

No results posted yet for this study

Summary

In this pre-post observational study, the investigators will enroll and follow a cohort of about 50 adults undergoing sleeve gastrectomy surgery for weight loss. Pre-operatively and at 6 and 12 months post-operatively, the investigators will use state-of-the-art metabolic and imaging techniques to evaluate calcium metabolism and skeletal health. Specific outcomes include intestinal calcium absorption capacity, bone mineral density (BMD) assessed by dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT), and bone structure assessed by QCT and high-resolution peripheral QCT (HR-pQCT).
