What is Continuous Glucose Monitoring?
CGM systems measure interstitial glucose continuously and present trends and alerts, reducing the need for frequent fingersticks and revealing patterns not visible from occasional checks.
Who Should Consider CGM?
- People with type 1 diabetes or type 2 diabetes using insulin.
- Those with frequent hypoglycemia or hypoglycemia unawareness.
- Individuals who want detailed insight into how lifestyle affects glucose.
Interpreting CGM Data
Focus on time-in-range (TIR), trend arrows, and patterns around meals/exercise. Work with a clinician or diabetes educator to convert insights into safe medication and lifestyle changes.
Practical Tips
- Pair CGM readings with a brief food/exercise log for 2 weeks.
- Use alerts for low and high glucose settings that match your clinical plan.
- Rotate sensor sites and follow manufacturer guidance to maximize accuracy.
