What is the Dexcom G6?

The Dexcom G6 is Dexcom’s latest generation continuous glucose monitoring (CGM) system. Unlike previous generations, this CGM system is factory-calibrated—so zero fingersticks are required.* The Dexcom G6 is comprised of a sensor, transmitter and display device (receiver and/or compatible smart device)**. The system features a redesigned, one-touch auto-applicator and sleek, discreet transmitter. The Dexcom G6 sends glucose readings to a smart device or the Dexcom receiver every 5 minutes. The Dexcom G6 is approved for patients ages 2 and older.

*If your glucose alerts and readings from the G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.
