Are you getting way too many alerts from your Dexcom G7? Learn how to prevent alert fatigue by acknowledging them on your phone.
The Dexcom G7 Continuous Glucose Monitoring (CGM) System has a robust selection of alerts that are thoughtfully designed to improve your experience. By making Dexcom alerts work for you, you’ll enjoy a better overall experience and be able to take your diabetes management to the next level. In this series of articles, we will take you through different categories of alerts and teach you how not only to use them, but how to customize them to fit your needs.


There are several ways to acknowledge alerts listed below.

  1. When an alert appears, decide if you need to make a treatment decision or fix a system issue.
  2. Next tap OK on the alert. This tells your Dexcom G7 you're "acknowledging" it. Unless you do this, re-alerts will occur every 5 minutes.


Knowing how to manage and acknowledge your alerts can be beneficial to your entire CGM experience.
