Dexcom One Blood Glucose Sensor

What is the Dexcom One Glucose Sensor used for?

Please note that the meter complies with French standards and therefore displays results in mg/dL

The Dexcom One Blood Glucose Sensor is an innovative medical device designed to revolutionize daily diabetes management. It provides continuous glucose monitoring (CGM), eliminating the need for fingerstick tests multiple times a day. Thanks to its smart and discreet sensor system, it provides real-time data for constant and accurate monitoring of blood sugar levels.

This sensor is particularly useful for people with diabetes (type 1 or type 2) who want to better understand their blood glucose trends, quickly identify episodes of hypoglycemia or hyperglycemia, and adjust their treatment accordingly. The device is compatible with an intuitive mobile app that displays blood glucose readings, trend lines, and personalized alerts.

One of the main advantages of Dexcom One is its ease of use. Once applied, the sensor works for up to 10 days without interruption, transmitting data to your smartphone every 5 minutes. It thus helps you gain independence, confidence, and peace of mind, while making treatment decisions easier.

The sensor is recommended for children as young as 2 years old, including pregnant women. Its interstitial monitoring technology detects blood glucose fluctuations earlier, allowing youto anticipate drops or spikes. This is a real advantage in preventing both short- and long-term complications.

Thanks to its customizable alerts, you’re immediately notified if your blood sugar is too low or too high—even without checking your phone. These alerts help you stay within the target range of 70 to 180 mg/dL, which optimizes metabolic control and reduces the risks associated with poorly controlled diabetes.

Finally, the sensor fits seamlessly into an active lifestyle. Its compact design, comfort, and water resistance allow you to wear it while showering, exercising, or sleeping. The user-friendly interface, detailed reports, and compatibility with connected devices make Dexcom One a comprehensive and reliable solution for proactive diabetes management.
