Dexcom G7
Looking for the most cutting-edge CGM on the market? Dexcom is a leader in CGM technology, and the Dexcom G7 CGM System is its most advanced yet—now available in two wear options:
- Original Dexcom G7—10 day wear time for ages 2 and up
- Dexcom G7 15-Day—15 day wear time for adults 18 and up
Dexcom G7 tracks glucose levels in real-time and sends the data to your receiver or smartphone via the app–no finger sticks required.* With glucose readings every 5 minutes and 180 days of data storage, you’re always in the know. Choose from a variety of customizable alerts, including delaying first alerts, “urgent low soon” alerts, and quiet mode with the Dexcom G7 app.
The G7 offers key improvements to its predecessor, the Dexcom G6. It has a shortened warm-up time of only 30 minutes, while other brands require at least an hour. The G7 also has a small all-in-one sensor/transmitter. You can read more on the G7's advancements in our guide on the Dexcom G6 vs G7.
The Dexcom G7 CGM system comes with a handheld receiver and a 90-day supply of sensors to get you started. Each sensor can be worn for up to 10 days, even in the shower. Already have the G7 receiver and are looking to replenish sensors? You can order Dexcom G7 sensors from US MED.
The Dexcom G7 may be covered by your insurance or Medicare plan. To see if you qualify, start your order or call us at 877-840-8218.
