The Dexcom G7 from Dexcom, Inc.

The all-in-one Dexcom G7 CGM system is indicated for individuals with diabetes ages 2 years and older. This newest offering from Dexcom features an approximate 60% decrease in size over the G6, a 30-minute sensor warm-up time and a twelve-hour grace period to replace expiring sensors. There are also enhanced alert settings and a redesigned mobile app.

Similar to the G6, The G7 delivers real-time glucose readings sent automatically every 5 minutes to a compatible display device* and is capable of integration with a wide array of popular devices.

Dexcom G7 connects to the Apple Watch with Direct to Watch using Bluetooth. When Direct to Watch is active, the sensor sends CGM data right to the watch so the phone is no longer needed to see glucose numbers.  For more information see Direct to Watch FAQ

Features for users include:

  • ability to see glucose data even when not near Smartphone
  • no cellular plan needed because Direct to Watch uses Bluetooth
  • real-time glucose data through share and to partner health apps is backfilled via smartphone connection

  • iPhone* that is running iOS 17 or later and an Apple Watch Series 6 or later running watchOS10 is required
  • Automated Activity & New Medication Logging:  Automated activity and new medication logging capability.  Logging medications and activity in the Dexcom G7 app connects the dots between lifestyle choices and glucose data.
