The 5-Minute CGM Guide for First-Timers
What Is a CGM?
A Continuous Glucose Monitor (CGM) is a small, wearable device that tracks your glucose levels day and night. Instead of pricking your finger several times a day, a sensor sends readings straight to your phone or reader.
Top CGMs Trinity Offers:
- Dexcom G7: Accurate readings, fast alerts, and a simple app interface
- FreeStyle Libre 3 Plus: Tiny, discreet sensor that updates regularly
Why So Many Patients Are Switching
- Less daily pain: No more routine finger-sticks
- Early alerts: See highs and lows before they become serious
- Peace of mind: View your numbers anytime, share with your care team
- Medicare coverage: Many patients qualify depending on coverage
How Trinity Makes It Easy

Pro Tips for New Users
- Apply when your previous sensor ends. Clean, dry skin helps it stay in place.
- Check your app daily—your glucose trends tell a bigger story than a single number
- Keep backup snacks handy if alerts indicate a drop
- Invite a caregiver to connect—they can receive alerts too
