Real-time glucose response
CGM (Continuous Glucose Monitor).
A two-week wearable that streams your glucose every five minutes. The only way to know how your body actually responds to your food, your sleep, and your stress.

Why it matters
A fasting glucose draw is one number from one moment. A CGM gives you roughly four thousand glucose readings in fourteen days, mapped to what you ate, when you slept, and what you did. The pattern is almost always more revealing than the average. Two people with identical HbA1c can have completely different glycemic variability, and variability is what damages tissue over time. The two weeks are also self-correcting: most patients change their eating before the sensor comes off, because the data is impossible to argue with.
What I read for
Mean glucose. Glucose variability. Time-in-range at optimal thresholds, not the diabetes-care default. Post-meal excursions and how fast they decay. Overnight stability. The personal foods, time-of-day patterns, and stress-glucose relationships that no textbook can predict.
