Dexcom are phasing out their Dexcom G6 continuous glucose monitor (CGM) and replacing it with the Dexcom G7.
If you currently use a Dexcom G6 continuous glucose monitor on its own or connected to an insulin pump to make a hybrid closed loop system, speak to your healthcare team at your next appointment about upgrading to the Dexcom G7.
Dexcom is supporting healthcare professionals with the transition, and you may be contacted by the Dexcom Transition Team before your next clinic appointment. If you are funding your own sensors, then you can buy the Dexcom G7 on Dexcom’s website.
Why is the Dexcom G6 being discontinued?
Dexcom is discontinuing the Dexcom G6 to focus on bringing people living with diabetes the latest technology through the Dexcom G7.
The Dexcom G7 is 60% smaller than the Dexcom G6, and it is an all-in-one discreet sensor that warms up in 30 minutes. It can be inserted on the abdomen, on the back of the upper arm (for users aged 2 years and older) or the upper buttocks (for users aged 2-6 years old).
The Dexcom G7 also has new alert options including:
- Delay 1st High alert, which lets users postpone an initial high glucose alert for 15 minutes to 4 hours, and can reduce alert fatigue after meals.
- Silent Mode, which temporarily mutes alerts for up to 6 hours, for when you need your CGM to be silent.
- A new mobile app that can be paired with Dexcom Clarity (an app Dexcom G6 users used to help with diabetes management). If you’ve previously used Dexcom Clarity or Dexcom Follow (an app for friends and family), you do not need to register again and can log in with your existing account details to maintain all your settings.
- Direct to Apple Watch, enabling users to send glucose data directly from the sensor to an Apple Watch via Bluetooth.
Dexcom says these new features will make it easier to help people manage living with diabetes.
When will the G6 be discontinued?
From 1 April 2026, you will no longer be able to choose the Dexcom G6 if you are not already using it. This allows Dexcom to prioritise existing Dexcom G6 users to ensure a reliable supply for them as they transition people to the Dexcom G7.
Dexcom says it will continue to work with healthcare teams to ensure users are supported, and recommends that people using the Dexcom G6 start the upgrade conversation at their next clinic appointment.
Compatibility with insulin pumps and pens
The G7 will be compatible with Dexcom’s pump and pen partners before discontinuing Dexcom G6.
Dexcom will release more information on timelines for connectivity of the DANA-I or MyLife YpsoPump insulin pumps as soon as they are confirmed.
Do I need to keep my Dexcom G6 transmitter?
No. The Dexcom G7 is an all-in-one sensor and transmitter, so there is no need for a separate transmitter.
Does Dexcom G7 require a new receiver, or can I use existing Dexcom G6 receiver?
Dexcom G6 receivers are not compatible with Dexcom G7 sensors. Dexcom G7 has a smaller receiver with a more vibrant, easier to read display. Please talk to your healthcare professional or diabetes team if you need a G7 receiver.
