See what fingersticks aren’t showing you
Blood glucose meters (BGMs) show a single reading in time, but your glucose levels are always changing. Without the full picture, you might miss highs or lows throughout the day.
Dexcom CGM Systems track your glucose 24/7 and alert you if levels go too high or too low. This real-time visibility can help you increase your time in range, lower your A1C, and reduce glucose spikes and drops.
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 CGM, 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
Glucose numbers 24/7
Continuous Glucose Monitoring Systems measure your glucose numbers 24/7 without fingersticks*, giving you real-time information to make better diabetes decisions. BGMs only give you a single glucose reading each time you prick your finger.

More informed diabetes decisions
CGM systems show the direction your glucose is heading – up, down, or steady – so you can see how food, activity, and insulin affect your levels. No more guessing! CGMs allow you to proactively manage your diabetes.
Lowers A1C
