The continuous glucose monitor — once a prescription-only device for diabetics — is now an over-the-counter wellness gadget. Dexcom’s Stelo and Abbott’s Lingo are FDA-cleared for adults without diabetes: a sensor on the back of your arm, worn up to 15 days, streaming your glucose to an app for around $99 a month. No finger pricks, no prescription.
Why it matters
It turns an invisible number visible. Seeing your glucose spike after a specific meal — and flatten after a walk — is a powerful behavior-change loop. For the metabolically curious, that feedback is the product.
A reality check: in people without diabetes, glucose “spikes” are usually normal and not a medical problem. A CGM is a learning tool, not a diagnosis — and it’s easy to over-interpret. Use it for a month to learn your patterns, not forever out of anxiety.
