What is Continuous Glucose Monitoring (CGM)?

Simply put, Continuous Glucose Monitoring (CGM) tracks glucose levels throughout the day and night and can alert you if your levels go too high or low. CGM systems take glucose measurements at regular intervals, 24/7, and translate them into dynamic data to show glucose direction and rate of change.

 

Dexcom CGM gives you a full picture of your glucose numbers & trends

Dexcom CGM tracks your glucose levels continuously throughout the day and night. Your glucose reading is sent to your smart device or receiver every five minutes. Dexcom CGM then translates your readings into dynamic data so you're better able to manage your diabetes treatment.

Proactively manage your diabetes with CGM

With continuous glucose monitoring, you'll get a clear picture of your glucose highs and lows, along with where your numbers are headed. This means you'll be able to see trends and gain insight into the impact that meals, exercise and illness can have on your glucose levels. In other words, Dexcom G6 helps to reduce the guesswork that comes with making diabetes treatment decisions.*

* If your glucose alerts and readings from the G6 do not match symptoms or expectations or you’re taking over the recommended maximum dosage amount of 1000mg of acetaminophen every 6 hours, use a blood glucose meter to make diabetes treatment decisions.

How does CGM work?

Instead of looking at one glucose number at a single moment in time, CGM tracks your glucose levels 24 hours a day. Here's how:

1. A tiny sensor wire is inserted under your skin using an automatic applicator

Users insert a tiny sensor wire just under the skin using an automatic applicator. An adhesive patch holds the CGM sensor in place so it can measure glucose readings in interstitial fluid throughout the day and night.

2. Your transmitter sends data

A small, reusable transmitter connects to the sensor wire and sends real-time readings wirelessly to a receiver so you can view the information. With some systems, a compatible smart device with the CGM system app can serve as the display device.

3. You receive updates & alerts

The receiver or compatible smart device displays current glucose levels, as well as historical trends in levels. The Dexcom CGM receiver and/or compatible smart device can also be set to send you custom alerts when certain glucose thresholds are reached.

Using a CGM helps reduce A1C Levels

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.1
