How Dexcom Continuous Glucose Monitoring (CGM) Works

The Dexcom G6 CGM is designed to make it easier than ever for people with Type I or Type II diabetes to manage these conditions. This diabetes monitor consists of three major components:

  1. A sensor and transmitter that keeps an eye on glucose levels under the skin.
  2. An auto-applicator that makes inserting sensors a cinch.
  3. A display device to check your glucose levels - either a dedicated touchscreen receiver or a compatible smart device.


These smartphones are recommended for use with the FreeStyle LibreLink app. Note that Android phones must have near-field communication features and use Android 7.1 or higher to be compatible with the app. Compatible iPhones must use iOS 13.2 or higher.

Frequently Asked Questions

US MED charges $500 cash/credit for a Dexcom G6 receiver. You will also need to purchase the transmitter and sensors separately. This is a discounted rate for customers who are purchasing the system without insurance.

Dexcom G6 sensors are designed to stay in place for up to 10 days.

Medicare does cover 80% of this system for patients who meet certain criteria. These criteria include - but are not limited to - using a blood glucose monitor to test glucose levels at least four times a day, receiving daily insulin treatment 3 injections or more per day, and regularly needing to adjust insulin treatments, being on an insulin sliding scale.

To remove your sensor, simply pull it off like a bandage. Once it’s fully off, pull the transmitter out of the sensor for reuse. Then, dispose of the used sensor before applying a new one.

The sensors and transmitters used in the Dexcom G6 system are water-resistant, assuming they are installed properly. The receiver is not water-resistant or waterproof.

The G6 sensor applicator has a small needle. As a result, when applying a Dexcom G6 CGM sensor, you’ll feel a slight pinch from the needle while the applicator pushes the sensor into the interstitial fluid under your skin. Once you’ve applied a sensor, the needle will retract into the plastic applicator - it won’t stay under your skin.

Sleeping while wearing a sensor should not cause any issues. However, you shouldn’t wear the sensor on a site that could easily be pushed or bumped.

Sensors can be worn on the abdomen by patients that are at least two years old. Patients between the ages of two and 17 can also wear sensors on the upper buttocks.

Metal detectors will not damage the Dexcom G6, but its components should not be X-rayed or taken through Advanced Imaging Technology body scanners.
