- G7 sensors are 60 percent smaller than those used in previous Dexcom CGM systems
- The sensor and transmitter are combined into one disposable device

The Dexcom G7 CGM All-in-one sensor and transmitter makes it easier than ever for users to track their glucose levels. CGM systems cannot replace fingerstick testing, but these systems can significantly reduce the frequency of these tests for people living with diabetes.
Dexcom G7® Sensor
The Dexcom G7® Sensor is Dexcom’s most advanced CGM sensor—now available in two wear options to fit your lifestyle:
- Dexcom G7 (10-day wear) – FDA-cleared for ages 2 and older
- Dexcom G7 15 Day (15.5-day wear including 12-hour grace period) – FDA-cleared for adults 18+
Both sensors deliver real-time glucose readings every 5 minutes, require no fingersticks*, and work with the Dexcom G7 app or receiver for easy monitoring. They feature customizable alerts, seamless data sharing through Dexcom Clarity and Dexcom Follow, and are approved for use during pregnancy.
Advanced Diabetes Supply offers the G7 Sensor 10-day and 15-day option in a 90-day supply with free, fast shipping! To learn if you may qualify for zero out-of-pocket costs, please reach out to our friendly intake agents for a complimentary benefits check at 866-422-4866 or fill out the form below.
