Best Continuous Glucose Monitors of 2025

**Editor’s note, June 25, 2024:** Since this article was first published, Dexcom has launched the G7. This sensor is smaller than the G6 and has an improved alert system, along with a few other differences.

“I find continuous glucose monitoring to be a valuable tool in the management of both type 1 and 2 diabetes,” said Dr. Josh Emdur, medical director of SteadyMD. “CGM data provides actionable insight to help patients track their glycemic response to dietary choices and activity levels.”

The Dexcom G6 doesn’t require you to manually scan to get a glucose level reading; instead, you get a wireless reading either on a dedicated receiver device or to your phone or Apple Watch. The Dexcom G6 reads your blood sugar every 5 minutes, keeping track of your blood sugar level as long as you’re wearing it night and day. You can set a custom range for where you’d like your blood sugar to be, and if it goes into low blood sugar or high blood sugar ranges you set, you will get notified. 

“For patients on an insulin pump, the Dexcom G6 may connect with your pump and offer a closed-loop system to turn off your insulin if you are going low. The Dexcom monitor is also approved in pregnancy and offers continuous monitoring that you can see on your phone at all times,” said Dr. Rebecca Fenichel, an endocrinologist at Westmed Medical Group.
