See your real-time glucose numbers 24/7 without routine fingersticks‡
Dexcom G7 and Dexcom G7 15 Day CGM Systems make managing diabetes easier and more effective.†,8-12
They track your glucose levels in real-time and send them to your phone* or receiver — so you always know where your numbers are, where they’ve been, and where they’re headed.
‡Fingersticks required for diabetes treatment decisions if symptoms or expectations do not match readings.
See what fingersticks aren't showing you
Blood glucose meters (BGMs) show a single reading in time—but 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 is proven to increase time in range, lower A1C, and reduce glucose spikes and drops.2-5,7
BGM and CGM readings often differ, and that's normal.
Why time in range matters—and how Dexcom CGM helps
Time in range (TIR) is the amount of time your body's glucose is within a target range. For most people with diabetes the ideal range is between 3.9 - 10 mmol/L. The more time people spend in the green zone, the better they report feeling.14
Beyond A1C: a clearer picture of glucose control
While A1C gives an average of your glucose over 2–3 months, it doesn’t show the highs and lows. Time in range fills in the gaps.
- Glucose variability: how much your levels fluctuate
- Patterns of highs and lows: when and why they happen
- Real-time insights: to guide daily decisions
