After 10 days of usage, your Dexcom G7 CGM will expire. You will receive a notification and see your sensor status updated to “expired” in the Dexcom G7 app.
How Long do I Have Left on my Dexcom G7 Sensor?
To see how many days you have remaining on the sensor:
- Open your Dexcom G7 app
- Tap on “Connections” along the bottom of the screen
- Tap on “Sensor” at the top of the screen
- This section will show how many days you have remaining on your current sensor. If nothing is shown there, then your sensor is not activated.
How to Remove the Dexcom G7 Sensor
After you see the expiration message, you can do the following:
- Disconnect your Sensor: open the Dexcom G7 app, tap on “Connections” along the bottom of the screen, tap on “Sensor” at the top of the screen, then tap on the “STOP SENSOR SESSION” button.
- Peel off the Nutrisense Protective Patch: lift the edge of the adhesive and pull it from the skin.
- Remove the CGM: pinch a small portion of the adhesive attached to your skin and pull it up and towards the center of your CGM, as you would a bandaid. The device should come off easily. If you need help removing the CGM, we recommend applying baby oil or vegetable oil for 5-10 minutes prior to removal.
- Discard the CGM – it cannot be reused or recycled. You can wrap the used CGM in a tissue, toilet paper, or paper towel and throw it in the trash. Don't worry, there is no needle in the CGM, so it is safe to throw out!

Note: It's ok to take a break between CGMs. You are free to use your CGMs with Nutrisense at the frequency of your choice, but bear in mind that CGMs have an expiration date, so ensure that you use your CGMs before they expire. Please also bear in mind that the Dexcom G7 study sensors can only be used while you are enrolled in the study; you must properly dispose of any remaining study sensors.
