Medical Nutrition Therapy Using Continuous Glucose Monitoring System

  • 1Department of Food Service and Nutrition Care, Seoul National University Hospital, Seoul, Korea


Medical nutrition therapy plays an integral role in diabetes management. There is no “one-size-fits-all” eating pattern for those with diabetes, and meal planning should be individualized. For many people with diabetes, glucose monitoring is key for glycemic control. Continuous glucose monitoring (CGM) metrics are suggested to provide a personalized diabetes management plan. Use of CGM continues to expand in clinical practice. Integrating CGM results into diabetes management can be useful for guiding medical nutrition therapy and physical activity, preventing hypoglycemia, and adjusting medications. Clinical dietitians should develop personalized nutrition management using CGM to help people with diabetes optimize dietary intake.
