Continuous Glucose Monitoring
Continuous glucose monitoring streams day-long glucose trends to reveal meal, sleep, and stress effects beyond single lab snapshots.
Continuous glucose monitoring (CGM) uses a wearable sensor to stream interstitial glucose trends through the day for people with diabetes and, increasingly, wellness learners optimizing meals and training. It reveals post-meal spikes, dawn phenomena, and alcohol effects invisible on annual labs.
Context matters—stress and poor sleep skew curves.
Common questions
-
Can healthy people use CGM for nutrition?
Some use CGM short term to learn meal responses; it is not required for health. Pair insights with protein, fiber, sleep, and movement—not fear of every spike.
