The Dexcom G7 rtCGM System

The most accurate glucose sensor available in Canada†,1, Dexcom G7 is proven to improve diabetes outcomes2-6, and is our easiest to use, most discreet CGM. Dexcom G7 measures glucose levels up to every 5 minutes, and sends readings wirelessly to a smart device or optional receiver, giving people actionable glucose data – without the need for routine fingersticks* or scanning.

Powering Confident Decisions That Lead To Better Outcomes2-6

Diabetes Canada Guidelines recommend real-time CGM, like Dexcom G7, as a standard of care.‡,7 And when compared to Freestyle Libre isCGM across diabetes outcomes in a real-world study, Dexcom rtCGM came out on top.

  • The most accurate CGM system*,1
    MARD (back of upper arm):§,9,10
    Adults: 8.2% vs. 9.2% for FreeStyle Libre 2
    Pediatrics: 8.1% vs. 9.7% for FreeStyle Libre 2
  • Associated with significantly better real-world glycemic outcomes vs. Freestyle Libre isCGM¶,8
    Greater A1C reduction (-0.7% vs. -0.5%; adjusted mean difference: -0.3%, p=0.01)
    More time in range (1 more hour/day in range, p=0.03)
    Less hypoglycemia (1 less hour/day below range, p<0.001)
  • Only Dexcom rtCGM has a predictive Urgent Low Soon alert
    Up to 20-minute advanced warning when glucose is headed towards severe hypoglycemia (<3.1 mmol/L), so people can take immediate action.9 
  • Easier than ever to use – and to continue using 
    Easy to prescribe, easy to insert and easy to customize. 9 out of 10 users stay on Dexcom rtCGM after 1 year.††,11
  • Designed for all types of diabetes
    Can be used in the widest range of people with diabetes (type 1 & type 2 diabetes, pregnancy, children >2 years of age).

Dexcom G7 Components

With a new all-in-one sensor, Dexcom G7 can be easily inserted with one push. After a 30-minute warm up – the shortest of any CGM – people will be able to view real-time glucose data on a compatible smart device or receiver. Plus, with a new 12-hour grace period, they can change their sensor when it’s more convenient.9 

Dexcom G7 Sensor
All-in-One Sensor

All-in-one sensor monitors interstitial glucose levels through a small wire inserted just underneath the skin, and sends glucose readings up to every 5 minutes wirelessly via Bluetooth to the wearer's display device†
(Length of sensor wear: 10 days + 12-hour grace period)

Dexcom G7
Display Device

Allows people to view their real-time glucose data and trends, receive alerts and alarms, and other notifications on their compatible smart device or receiver.

Dexcom G7 App

Our redesigned app allows people to easily see where their glucose levels are heading and how fast, keeping them engaged and motivated. It also offers greater customization, including a new Delay 1st Alert and the ability to silence all alerts when desired.9 Plus, the app now provides integration of Dexcom Clarity data, for better management decisions.//

‡ In people with type 1 diabetes using basal-bolus insulin therapy or CSII, or with impaired awareness of or recent severe hypoglycemia; and in people with type 2 diabetes using basal-bolus insulin therapy who have not achieved their A1C target. 
§ Mean absolute relative difference (MARD) is a statistical measure of accuracy. The lower the number, the more accurate.
¶ Retrospective, real-world observational analysis of the Canadian LMC Diabetes Registry using the medical records of 143 consenting CGM-naïve adults with type 1 diabetes (T1D) in each rtCGM and isCGM matched cohorts. To be eligible, people must have had: diagnosis of T1D >12 months, baseline A1C >7.0%, and 1 or more completed HbA1c measurements 6 months prior and 6-12 months post-index date.
