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.5-10
BGM and CGM readings often differ, and that's normal.
Beyond A1C: a clearer picture of glucose management
While A1C gives an average of your glucose over two to three months, it doesn’t show the highs and lows. Time in range fills in the gaps by revealing:
- Glucose variability: how much your levels fluctuate
- Patterns of highs and lows: when and why they happen
- Real-time insights: to guide daily decisions
Did you know? A 10% increase in time in range can reduce A1C by approximately 0.8%!11
