Benefits of continuous glucose monitoring vs. blood glucose monitoring

What is the difference between CGM and BGM? Blood Glucose Meters (BGM) measure glucose levels at a single moment in time, while Dexcom Continuous Glucose Monitoring (CGM) systems continually check glucose levels throughout the day and night and can alert you if your glucose levels go too high or too low.

no more fingersticks!*

BGMs require fingersticks to give you a single reading at a moment in time. CGMs, on the other hand, provide continuous glucose readings 24/7 to your compatible smart device without fingersticks.* CGMs also have proven accuracy1 without painful and inconvenient fingersticks. Say goodbye to fingersticks!
*For the Dexcom G6, if your glucose alerts and readings from your CGM do not match symptoms or expectations, use a blood glucose meter to make your diabetes treatment decisions. Please see the indications for use for all other CGM system to understand the important safety information
