CGM
Also written as: CGM — continuous glucose monitoring
Continuous glucose monitoring device that tracks interstitial glucose levels in real-time.
Full Definition
Continuous glucose monitoring (CGM) systems are wearable devices that measure glucose concentrations in interstitial fluid, providing real-time glucose readings and trends throughout the day and night. CGM technology includes sensors that last 7-14 days, transmitters that send data wirelessly, and receivers or smartphone apps that display glucose information. These devices provide valuable insights into glucose patterns, detect hypoglycemic episodes, and help optimize diabetes management through features like glucose alarms and trend arrows. CGM data is particularly useful for adjusting insulin dosing, identifying dawn phenomenon, and improving time-in-range metrics.
