Dexcom’s latest G7 continuous glucose monitor (CGM) is the company’s smallest and smartest sensor yet. With a compact all-in-one design, 30-minute warm-up, and a 12-hour grace period, G7 is a huge upgrade over its predecessor, the Dexcom G6.
Our review dives into what worked, what didn’t, and how G7 is evolving as it expands support for more automated insulin delivery (AID) systems. After over six months of daily wear, I share my honest take on the pros, the quirks, and the features you may not notice until you’ve lived with the device.
Here’s a quick rundown of the Dexcom G7 features:
60% smaller sensor than G6
30-minute warm-up time
No calibrations needed, optional calibrations allowed
Dexcom Clarity on the Home Screen
Real-time sharing with up to 10 followers
Predictive low alerts up to 20 minutes ahead
Dexcom also recently secured FDA clearance for a 15-Day G7 sensor, extending wear time while also improving the on-board algorithm and increasing accuracy.
If you’re curious how the Dexcom G7 holds up over time, I break it all down in my latest video — the good, the frustrating, and everything in between. From sensor changes to sleep alerts and AID integration, I cover what you need to know before deciding if it’s the right CGM for you. Watch the full breakdown at the top of the page.
