What is Continuous Glucose Monitoring (CGM)?

A continuous glucose monitor (CGM) is an FDA-­approved device that provides continuous insight into glucose levels throughout the day and night. CGM also displays information about glucose direction and speed giving users additional information to help with their diabetes management. CGM also provides customizable alerts to warn the wearer of approaching glucose highs and lows. Studies have shown that CGM contributes to a decrease in HbA1c without increasing the risk for hypoglycemia.1

How is Dexcom CGM different from a blood glucose meter?

The traditional method of measuring glucose levels requires a fingerstick using a blood glucose meter (BGM). BGMs provide a glucose reading at a single point in time. The key difference between Dexcom CGM and BGM is that Dexcom CGM provides glucose readings throughout the day and night, including glucose speed and direction arrows that empower wearers with more information for more informed decision making*.
