However, the usefulness and detailed data during perioperative status were not well studied. In this study, we described the immediate changes of glucose profiles after metabolic surgery using intermittently scanned CGM (isCGM) in individuals with type 2 diabetes mellitus (T2DM).<h4>Methods</h4>This was a prospective, single-center, single-arm study including 20 participants with T2DM. The isCGM (FreeStyle Libre CGM) implantation was performed within 2 weeks before surgery. We compared CGM metrics of 3 days before surgery and 3 days after surgery, and performed the correlation analyses with clinical variables.<h4>Results</h4>The mean glucose significantly decreased after surgery (147.Diabetes & metabolism journal713-721https://www.ebi.ac.uk/biostudies/studies/S-EPMC9532174biostudies-literatureGlucose Profiles Assessed by Intermittently Scanned Continuous Glucose Monitoring System during the Perioperative Period of Metabolic Surgery.PMC9532174Park YSChoi SHOh TJKim KJang HCfalseGlucose Profiles Assessed by Intermittently Scanned Continuous Glucose Monitoring System during the Perioperative Period of Metabolic Surgery.<h4>Background</h4>Continuous glucose monitoring (CGM) has been widely used in the management of diabetes.
