How does DexCom CGM work?

DexCom CGM, or Continuous Glucose Monitoring, works by measuring glucose levels continuously throughout the day and night. The system consists of a small sensor inserted under the skin, a transmitter that sends data from the sensor to a receiver or compatible smart device, and a mobile app for viewing glucose trends. The sensor detects glucose in the interstitial fluid and sends real-time measurements to the receiver or smart device, allowing users to track their glucose levels without the need for frequent fingersticks. The readings are displayed on the device's screen or mobile app, providing users with immediate feedback on their glucose levels. DexCom CGM helps users make informed decisions about managing their diabetes by alerting them to high or low glucose levels, helping to prevent dangerous fluctuations and improve overall glucose control.
