CGM for Non-Diabetics: What the Data Can Tell You

Continuous glucose monitors (CGMs) measure glucose in the fluid under your skin every few minutes, and they’re increasingly being used by people who don’t have diabetes too. This guide breaks down what those numbers actually mean—and what they don’t mean—so you don’t overreact to normal ups and downs.
