An introduction to Dexcom Continuous Glucose Monitoring


Continuous Glucose Monitoring (or CGM) systems measure your interstitial glucose levels 24 hours a day to reveal a complete view of glucose highs, lows and rates of change over time.

Unlike fingerpricks that give a number for a single point in time, CGM provides dynamic glucose information by showing you, every 5 minutes, where your glucose is, where it’s going and how fast it’s getting there.

About CGM

With CGM, a small sensor inserted beneath your skin transmits glucose readings to the Dexcom G5 Mobile System. You can see if your glucose is going up or going down and how fast it’s getting there and also view your trends across various blocks of time.

The Dexcom G5 Mobile System gives you the freedom to view your results directly on your compatible mobile device or receiver without the need for confirmatory fingerprick testing.* The idea is to use CGM to determine the direction your glucose is headed and the rate of change.

Here’s a closer look at how the Dexcom G5 Mobile System works.

About the sensor.

The sensor is a wire inserted underneath your skin with the help of an insertion device and held in place with adhesive, similar to the way an insulin pump infusion set is attached.

It continuously reads the glucose levels in the fluid in your tissues (called interstitial fluid). Sensors are disposable. Dexcom sensors are approved for 7 days of wear.

About the transmitter.

The transmitter clips into place inside a plastic sensor pod that’s attached to the adhesive and sensor. It sends your sensor-measured glucose readings to your Dexcom receiver or compatible smart device (with Dexcom G5 Mobile).

Find out more about the Dexcom G5 Mobile System and consult with your healthcare professional to see if this system is right for you.

†Glucose values are not visible during the 2-hour start-up period. Always refer to your healthcare professional team for treatment and insulin adjustment decisions.

*If your glucose alerts and readings do not match your symptoms or expectations, you should obtain a fingerprick. A minimum of two fingerpricks a day are required for calibration. *ALWAYS READ THE LABEL AND USE ONLY AS DIRECTED. YOUR DOCTOR WILL ADVISE YOU WHETHER THIS PRODUCT IS SUITABLE FOR YOU.
