A glucose sensor for diabetes is the part of a continuous glucose monitoring (CGM) system that is inserted under the skin, which allows it to measure your glucose levels.

How do glucose sensors work?

A glucose sensor connects to a transmitter which sends your glucose data wirelessly to your CGM system receiver or a compatible smart device, helping you monitor your glucose levels and lows at regular intervals and make more informed diabetes treatment decisions.

Dexcom G6 is an FDA-permitted CGM system for type 1 and type 2 diabetes that lets you make diabetes treatment decisions without fingersticks or calibrations.* The system includes a simple auto-applicator, a sensor, a transmitter, and a display device, such as a receiver or compatible smart device. The Dexcom G6 sensor is a tiny, water-resistant sensor that you can easily insert and wear for 10 days. The sensor accurately measures glucose levels just beneath the surface of the skin. The sensor is connected to a transmitter that is placed over the sensor and sends data every 5 minutes to your compatible smart device or receiver.

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