Dexcom ONE Sensor

About Dexcom ONE Sensor

The Dexcom ONE Sensor is an advanced continuous glucose monitoring (CGM) sensor designed for people living with diabetes to track glucose levels in real time without routine finger pricks or manual calibration. It uses a tiny, flexible filament placed just under the skin to continuously measure glucose levels in interstitial fluid and send automatic updates every few minutes straight to your compatible smartphone or optional receiver. Dexcom ONE helps you better understand glucose trends, manage highs and lows, and make informed treatment decisions more confidently.
Dexcom ONE Sensor is suitable for people aged 2 years and older with Type 1 or Type 2 diabetes and is water‑resistant, comfortable to wear, and ideal for both daily diabetes management and long‑term glucose control.

What Is the Dexcom ONE Sensor Used For?

The Dexcom ONE Sensor is used to provide continuous real‑time glucose readings and trends for people with diabetes, helping users detect rising and falling glucose levels throughout the day and night and make timely decisions about food, activity, and insulin dosing.

Who Is the Dexcom ONE Sensor Suitable For?

Dexcom ONE is suitable for individuals aged 2 years and over with Type 1 or Type 2 diabetes who want ongoing glucose monitoring without the need for frequent finger‑stick testing.
