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*.

What are the benefits of continuous glucose monitoring (CGM)?
