The Dexcom Continuous Glucose Monitoring (CGM) systems redefine diabetes management by providing real-time, highly accurate glucose data without the need for routine fingersticks.² At National Diabetic Supply, we offer the essential components for both the proven Dexcom G6 and the advanced Dexcom G7 systems. The Dexcom G6 features separate components—the Dexcom G6 Sensor and the Dexcom G6 Transmitter—ideal for seamless integration with compatible automated insulin delivery (AID) systems like Omnipod 5.³ The next-generation Dexcom G7 Receiver and its integrated sensor boast a smaller size, faster 30-minute warm-up time, and enhanced accuracy.⁴ Whether you prioritize existing pump compatibility or the latest innovations in size and speed, we supply the reliable Dexcom components you need for informed, confident care.

Features

• Real-Time Data: Both G6 and G7 sensors automatically send glucose readings every five minutes to a compatible display device, including the dedicated Dexcom G6 Receiver or Dexcom G7 Receiver.⁵
• No Routine Fingersticks: Both systems are factory-calibrated, eliminating the need for routine fingerstick tests for treatment decisions (if readings match symptoms/expectations).
• G7 All-in-One Design: The Dexcom G7 features a discreet, 60% smaller, all-in-one sensor and transmitter unit, simplifying application and wear.⁶
• Alert Customization: Both systems offer customizable alerts for high and low glucose levels, including the Urgent Low Soon warning, to proactively manage glucose excursions.⁷
• G6 System Components: Utilize the separate Dexcom G6 Sensor (10-day wear) and the reusable Dexcom G6 Transmitter (up to 90 days) for established AID system connectivity.⁸
