The Dexcom G7 CGM System
Dexcom G7 is built with safety in mind, automatically sending your glucose readings to your phone* or optional receiver in real time. It also works with compatible automated insulin delivery (AID) systems, all without the need for constant finger pricks.†
This lets you easily see where your glucose is now and where it’s going, helping you feel more confident making everyday choices about food, activity, and medications.1-5
Designed to ease the day‑to‑day effort of managing type 1 diabetes, Dexcom G7 provides continuous glucose readings 24/7 to help reduce daily stress6 and let you focus on what matters most to you.
