What is a glucose sensor?
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.

What is a glucometer?
A glucometer, also known as a glucose meter or blood glucose monitoring device, is a home measurement system you can use to test the amount of glucose (sugar) in your blood.
How is Dexcom CGM different from a blood glucose meter?
The traditional method of measuring glucose levels requires a fingerstick using a blood glucose meter (BGM). BGMs provide a glucose reading at a single point in time. The key difference between Dexcom CGM and BGM is that Dexcom CGM provides glucose readings throughout the day and night, including glucose speed and direction arrows that empower wearers with more information for more informed decision making*.
