Continuous Glucose Monitors (CGM)

CGMs provide real-time, minute-by-minute data on interstitial fluid glucose levels, revealing hidden spikes and crashes that fasting glucose and HbA1c miss.

Metrics to Track

Metric Longevity Target
Average Glucose< 100 mg/dL
Time in Range (70-140 mg/dL)> 95%
Glycemic Variability (CV)< 15%

Common Mistakes

  • Fearing Normal Spikes: It is normal for glucose to rise during intense exercise (due to cortisol and adrenaline). This is not pathological.
  • Sensor Lag: CGMs read interstitial fluid, which lags blood glucose by 10-15 minutes.

Frequently Asked Questions

Q: Should non-diabetics wear them?
A: Yes, occasionally. Wearing one for 2-4 weeks provides enough insight into how your specific body reacts to sleep deprivation, stress, and specific meals.
