What is continuous glucose monitoring (CGM)?
The Dexcom G7 15 Day CGM system is a small sensor worn on the back of your upper arm that can be used during pregnancy for all types of diabetes (type 1, type 2, and gestational). It continuously measures and displays your glucose numbers on your phone* in real-time showing you where your glucose is, where it’s headed, and where it’s been.
The more you wear your Dexcom G7 15 Day, the better you’ll understand how food, exercise, medications, stress, illness, and sleep affect your glucose, enabling you to make confident diabetes decisions for the health of you and your baby.

Customize a Target Range specific to you and your baby’s needs
Customized target ranges allow you and your doctor to set individualized glucose targets based on your specific health needs. The ADA target range recommendation for Type 1 and Type 2 diabetes is 70 mg/dl – 180 mg/dl, but for pregnancy the recommended target range is 63-140mg/dL.1 With Dexcom G7 15 Day, you can set your own customized target glucose range in both the Dexcom G7 app and in Clarity, to better suit your unique circumstances.
Customizing your alerts
Dexcom G7 15 Day alerts can notify you before your glucose goes too low†† and when it is high, empowering you to take action to better stay in range. You can work with your doctor to customize your alerts to fit your pregnancy goals.
