Abstract

Introduction: Changes in bone metabolism following Roux-en-Y Gastric Bypass (RYGB) in obese patients have yielded inconsistent results. Nevertheless, no data exist on changes in Calcium (Ca) metabolism after RYGB in Chinese obese subjects. Objectives: The aim of this study was to identify the impact of RYGB on vitamin D, Parathyroid Hormone (PTH), Ca and Phosphorus (P) metabolism in Chinese obese patients, and predictors of postoperative change. Methods: The patient undergoing RYGB between January 2015 and October 2018 in our hospital was retrospectively reviewed. Serum PTH, P, Ca, and 25-hydroxyvitamin D (25OHD) levels were collected before and 6 months after RYGB. Result: In total, 165 patients were included in the study. After RYGB, the mean Body Mass Index (BMI) level significantly reduced, the Ca, P and 25OHD levels increased, while the PTH level remained similar. Preoperative PTH level, percentage of Excess Weight Loss (%EWL), and BMI change were independent predictors of postoperative PTH change. Preoperative P and Ca levels could predict postoperative P and Ca change, respectively. Conclusion: A significant increase in serum 25OHD, Ca, and P are expected after RYGB at the short term. And preoperative 25OHDand Ca levels are predictors of postoperative change.
