The CGM sensor has a preset life of up to 14 days. CGMs are designed to work continuously and cannot be reinserted once removed. Please keep the sensor attached for the entire 14-day duration until the app shows that it needs to be replaced.
If you decide that you'd like to take the CGM off prior to the expiration, please reach out to customer support before it is removed through the in-app chat.
Each CGM is designed for a single-use and can be discarded in the trash after 14 days, once the app indicates that it has expired.
