Why choose a Dexcom Continuous Glucose Monitoring (CGM) system?
Dexcom CGM Systems measures your glucose levels every five minutes and transmits these readings to your compatible smartphone or device† – helping you to monitor and manage your glucose levels.
Using a glucose sensor that sits just beneath the skin, continuous glucose monitoring for type 2 diabetes offers several advantages in comparison with traditional blood sugar monitoring, including:
  • Allowing users to check blood glucose without pricking a finger*.
  • Providing key trends data that arm users and their health professionals with the knowledge to adjust their diet or medication .
  • Alerting users when blood glucose levels fall out of normal parameters.
Using a CGM for monitoring type 2 diabetes also helps users to track how food and drink affects their glucose levels, helping them to make informed choices about their diet and eating habits.

Increasingly agile

Our CGM systems are easy to use. The auto-applicator inserts a small glucose sensor just beneath the skin with just one push of a button and measures the glucose levels in the interstitial fluid around your cells.
Perfect for those routinely on the move, the Dexcom CGM Systems provide continuous readings to your compatible smartphone or device†, wherever you may be. Simply secure the sensor with an adhesive patch, attach the small transmitter, and you’re ready to go.
The glucose sensor removes the need for finger prick tests* and can be worn up to 10 days. It can be placed on the abdomen and the back of the upper arms.
Once snapped into place, the transmitter will remain operational for 90 days. Both the sensor and transmitter are completely water resistant‡ in up to 2.4 metres of water, so you can swim, shower or bathe in confidence. Dexcom users have even worn their CGM whilst scuba diving, sky diving and performing on stage!

Comfortable and discreet

Unlike a traditional type 2 diabetes monitoring system, a CGM system allows you to check your blood glucose levels discreetly and conveniently. The Dexcom CGM glucose sensor can be worn in several locations and will automatically record glucose levels without input from the wearer. It continues to work from beneath clothing – perfect for people who prefer to manage their diabetes privately.

Customisable glucose alerts

The Dexcom CGM for type 2 diabetes provides tailored glucose alerts, informing users whether their glucose levels are too high or too low. Users can also access unique display reports by pairing the monitor to the Dexcom app on a compatible device† using a Bluetooth connection.
Users can even receive personalised reports over certain periods, with summaries ranging from 3, 7, 14, 30, or 90 days, and review detailed information on average glucose, estimated HbA1C and the time your glucose within normal range.
Supported by medical professionals
Dexcom CGM makes life easier for medical professionals and patients. A real-time CGM enables you to share† § glucose readings with your family doctor or diabetes specialist for additional support and advice on managing your condition.
Not only is using a Dexcom CGM for type 2 diabetes monitoring easy and convenient, but a study1 has found that there is potential for continuous glucose monitoring to improve glycemic outcomes, prevent diabetes complications for type 2 diabetes and improve lifestyle management.
