What is a continuous glucose monitoring (CGM) device?
A continuous glucose monitoring (CGM) device tracks glucose levels throughout the day and night and can alert you if your levels go too low or when you’re high. It measures your glucose level at regular intervals, as frequently as every 5 minutes, and translates the readings into easy-to-read data and insights. It can also show the direction your glucose is heading and how fast.
Better diabetes management with a Dexcom CGM System
A Dexcom CGM system is an FDA-cleared wearable device that tracks your glucose levels continuously throughout the day and night. Your glucose reading is sent to your smartphone, smart device† or receiver as frequently as every five minutes. Dexcom CGM systems then translate your readings into dynamic data so you're better able to manage your diabetes treatment.
Glucose at a glance for more informed decisions
See your glucose numbers right on your smart device† or receiver without fingersticks. You can even see the direction your glucose is heading – up, down, or steady, so you can make better decisions about food, activity, and insulin in the moment. With Dexcom CGM, there’s no more guessing, making diabetes management easier.*

How does a continuous glucose monitoring system work?
Instead of looking at one glucose number at a single moment in time, a CGM system tracks your glucose levels day and night. Here's how:
1. Easy, painless application1
Users insert a slim sensor wire under their skin using an automatic applicator. An adhesive patch holds the CGM device in place so it can measure glucose readings in interstitial fluid 24/7.
2. Small, discreet wearable
A small, reusable transmitter connects to the sensor wire and sends real-time readings automatically to a smart device† or receiver so you can view your numbers without fingersticks.*

3. Real-time numbers & alerts
The compatible smart device† displays current glucose levels, as well as historical trends. Set customizable alerts that can warn you of highs and lows.
CGM systems can help you lower your A1C2-6
Studies have shown that use of some CGM systems may help reduce A1C levels and reduce risk of hypoglycemia, whether users are on insulin injections or pump therapy.7
