Using Continuous Glucose Monitoring for Patients Who Have Undergone Metabolic Surgery
Diabetes mellitus (DM) is a chronic disease, and its treatment measures include diet therapy, moderate exercise, medication, glucose monitoring, and diabetes education. Over the past decade, metabolic surgery has become an important means for treating obese patients with type 2 diabetes mellitus (T2DM) that makes long-term remission or even reversal possible. Although metabolic surgery can significantly improve the overall blood glucose levels and effectively reduce the glycated hemoglobin A1c (HbA1c), the improvement of glucose variability varies after different surgical procedures. Continuous glucose monitoring (CGM) is an effective means to evaluate glucose variability. We previously compared the preoperative and 1-year postoperative CGM data of 43 obese patients with type 2 diabetes who underwent Roux-en-Y gastric bypass (RYGB), and we found patients’ HbA1c levels were improved after the operation but the mean amplitude of glycemic excursion (MAGE) levels was not. Thus, postoperative glucose variability after RYGB and its interventions remain to be major challenges.
