MORE INSIGHT FOR BETTER GLUCOSE CONTROL
What is Continuous Glucose Monitoring (CGM)?

CGM gives users a more complete picture of their glucose levels and trends. Unlike a blood glucose meter which provides just a single reading with each fingerstick, CGM shows people with diabetes where their glucose is headed and how fast.

Continuous insight, day and night

CGM helps minimize the guesswork that typically comes from making decisions based solely on a single number from a blood glucose meter. CGM systems display information about glucose direction and rate of change up to every 5 minutes, providing people with critical information to help inform their diabetes management decisions.

rtCGM data is continuous and offers more data than a standard glucose meter

More peace of mind

Every day, people are frequently making decisions about their diabetes – when they eat, go for a run, or go to bed. With a Dexcom CGM system, these decisions are not made blindly, but instead with the knowledge of what their current glucose level is, where it's headed, and how fast. Dexcom G7’s customizable alerts and alarm can warn users if glucose levels go high or low.
