Dexcom G7 Continuous Glucose Monitor Receives FDA Clearance

Dexcom announced last week that its G7 Continuous Glucose Monitoring System had received FDA clearance.

The CGM fits on the back of the upper arm or upper buttocks for pediatric patients if they prefer, and sends glucose readings to a compatible smart device or a Dexcom receiver.

Dexcom touts a sensor warm-up of 30 minutes for the G7, which it compares to an hour or more for competing CGM brands. It also offers customizable alerts for high or low blood sugar and a predictive alert that can offer a 20-minute warning before potentially dangerous blood sugar levels.

The company said it is working with insulin pump vendors to integrate the G7 into current and future automated delivery systems.

“When we set out to design G7, our goal was simple: to provide people with diabetes, whether type 1 or type 2, with the most powerful and easy to use CGM. G7 stands fulfill that promise. And now that it has been cleared by the FDA, we look forward to bringing G7 to market in the coming months,” Dexcom Chairman and CEO Kevin Sayer said in a statement.

Our circuitry and chip in the G6 was developed in 2016-2017, and cybersecurity and Bluetooth have advanced significantly since then. So the new chips we have in this system will make again feel people safer.”
