Automatic glucose levels at a glance

Keeping a close eye on your glucose levels is crucial in managing your type 1 or type 2 diabetes. But this can feel like a never-ending numbers game that requires constant finger pricking and a lot of guesswork.
Dexcom Continuous Glucose Monitoring (CGM) Systems track your glucose levels automatically without finger pricks*. So, with a glance at your receiver or compatible smartphone†, you can view your numbers anytime and anywhere, helping you to take control of your diabetes.
What is CGM?
Continuous glucose monitoring (CGM) tracks your glucose levels 24 hours a day (throughout the day and night). Predictive alerts§ let you know if your levels are going to go too high or too low, reducing the risk of hyper- and hypoglycaemia.1
Instead of painful finger pricks*, a sensor measures glucose levels in your interstitial fluid every 5 minutes. It translates the readings into easy-to-read data and insights. Not only can you see your numbers in real-time, but it can also show the direction your glucose is heading and how fast. So, you can make preventative diabetes treatment decisions.
Why choose CGM?
Blood Glucose Monitoring (BGM) only gives you a snapshot of your blood sugar levels at a single moment in time.
Dexcom CGM takes up to 288 automatic readings every 24 hours. This turns static glucose readings into an ever-updating story. The effects of exercise, food and medicine can be seen in real-time on a receiver or compatible smartphone†, helping you to stay in your target glucose range.
Blood Glucose Monitoring
- Finger pricks are painful
- No overnight readings without waking up to finger prick
- Patients can only rely on symptoms of high/low glucose, if they have any
- Finger pricks only give you a snapshot in time of your blood sugar levels
Flash Glucose Monitoring
- Scanning may not give a 24-hour picture for treatment decisions - no overnight readings without waking up to scan
- In a recent study of patients using FGM, even those who scanned on average 40 times per day were generally still not meeting recommendations for time spent in target glucose range2,3
- The clinical benefits of scanning decrease over time in young people4,5
The Dexcom difference
By not having to finger prick* or scan, Dexcom CGM provides continuous and accurate‡ glucose management, giving you the freedom to live your life.
Who is CGM for?
CGM is a powerful tool for people living with type 1 diabetes (T1D) or type 2 diabetes (T2D), including pregnant women with diabetes. 6-9
According to the National Institute for Health and Care Excellence (NICE) guidelines, anyone with T1D should have access to CGM, as well as some people with T2D, such as children and those who use insulin therapy.10-13

How does Dexcom work?
Instead of looking at one glucose number at a single moment in time, Dexcom tracks your glucose levels day and night. Here's how it works:
1. Easy, painless application18
You insert a slim sensor wire just beneath your skin using an automatic applicator. An adhesive patch holds the sensor in place so it can measure glucose readings in your interstitial fluid 24/7.
2. Small, discreet wearable
A small transmitter connects to the sensor wire and sends automatic readings to a receiver or compatible smartphone† so you can view your numbers without finger pricks.*
3. Real-time numbers & alerts
The receiver or compatible smartphone† displays your current glucose levels, as well as historical trends. Set customisable alerts that can warn you of highs and lows (before they happen).
