Does anyone use CGM outside of diabetes?

so i keep seeing people mention CGM data showing patterns fasting labs never caught. but most of that seems diabetes-focused. i’m curious if anyone’s using one outside that box - like for thyroid metabolic stuff, or just tracking how food/stress/sleep impacts blood sugar when you’re not diabetic but clearly have metabolic dysfunction happening.

my fasting numbers look fine but i feel like i’m missing something. cold hands, afternoon crashes, weight resistance - it all points to something not showing up in quarterly labs. would a CGM actually catch that pattern in real time?

or is it overkill if insulin resistance isn’t officially diagnosed? anyone tried this? what did you actually learn that labs didn’t show?

anyway.
