What are the benefits of using Continuous Glucose Monitoring (CGM)?

Last Updated · February 11, 2022
  1. Zero fingersticks!*
    Enjoy the freedom of managing your diabetes without having to prick your fingers! The Dexcom ONE Continuous Glucose Monitoring system is designed to deliver accurate glucose readings without calibrations. It eliminates the need to take fingerstick measurements using a Blood Glucose Meter.*
  1. Know your sensor glucose readings with just a glance at your phone**
    Unlike blood glucose meters, which require a deliberate action to get a reading, a CGM system works continuously all day, even while you are asleep.

Your Dexcom CGM can provide you with 288 glucose readings every day, direct to your smartphone. The app will display your current glucose level and where it is heading; up, down, and at what pace.  You can get the full picture of your glucose levels & trends, all day every day.

  1. Get one step closer to better diabetes control
    Dexcom CGM technology can help you achieve your diabetes treatment goals. With Continuous Glucose Monitoring, you get the full picture of your glucose levels. You can see in real time how things such as food, exercise or stress affect your levels. It can help you make timely treatment decisions and avoid those rollercoaster highs and lows.
  1. Avoid hypoglycemia day and night
    When activated, the low glucose alert can warn you if you are falling below your pre-set low glucose levels, so you can take the necessary action. You can select the low threshold that suits you best and customise the alert sound or vibration.
  1. Enjoy more peace of mind
    Whether it is getting the good night’s sleep you deserve or simply enjoying some time outdoor with friends and family, Dexcom CGM can transform the way you live your life with diabetes and help you move closer to better diabetes control. Give it a try yourself! It doesn’t take long to see what a difference it can make.

*Fingersticks required when symptoms or expectations do not match CGM readings.
