How do Dexcom CGM sensors work with my body?

Continuous Glucose Monitoring (CGM) systems track glucose levels throughout the day. When used, a tiny sensor wire is inserted just underneath a person's skin using an automatic applicator. An adhesive patch holds the CGM sensor housing in place, so the sensor can measure glucose readings in interstitial fluid throughout the day and night. A small, reusable transmitter connects to the sensor wire and sends real-time readings wirelessly to a receiver, so that the user can view glucose information. Some systems also allow compatible smart devices to work with the CGM system app as display devices. Then, the receiver or compatible smart device* is able to display real-time glucose levels and historical trends. The CGM receiver and/or compatible smart device can also be set to send custom alerts to the user when certain glucose thresholds are reached.
