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.
