What This Guide Covers
A continuous glucose monitor (CGM) is a small wearable sensor that tracks glucose around the clock. For decades these were prescription devices for people with diabetes. In 2024 the FDA cleared the first over-the-counter sensors for adults not on insulin — and that is what made "wearing a CGM without diabetes" a legal-to-buy option.
What Is a CGM and How Does It Work?
A CGM is a coin-sized patch you apply to the back of your arm. A tiny filament sits just under the skin and measures glucose in interstitial fluid — not directly in your blood. The sensor sends a reading to your phone every few minutes.
- Each sensor lasts a set window — Stelo about 15 days; Lingo about 14 days — then you replace it.
- Readings lag real blood glucose by several minutes.
- The value is the trend, not any single number.
The OTC Shift: Stelo and Lingo
| Product | Maker | Cleared for |
|---|---|---|
| Stelo | Dexcom | OTC, adults 18+ not on insulin |
| Lingo | Abbott | OTC, adults 18+ not on insulin |
Stelo's indication is an over-the-counter iCGM for people 18 and older who are not on insulin. It is meant to show how lifestyle affects glucose — not to drive medical action without a clinician. Lingo uses the same "18+, not on insulin, not for diagnosis" frame.
Why Healthy People Wear One
- Food curiosity: seeing how a specific meal affects your glucose.
- Exercise timing: watching how a walk after dinner flattens a spike.
- Sleep and stress: noticing that a bad night can nudge glucose up.
This is self-experimentation. Research on lasting health improvements in healthy people is still emerging. The strongest personal value tends to be awareness, not a guaranteed medical outcome.
Accuracy & Caveats
- Read the curve, not the digit.
- Expect lag after a meal or workout.
- Compression lows are real if you lie on the sensor overnight.
- Not a diagnostic tool. OTC wellness CGMs are not for diagnosing or managing diabetes.

Insurance generally does not cover CGMs for people without diabetes, so this is typically an out-of-pocket purchase. Stelo and Lingo both advertise HSA/FSA eligibility — confirm with your plan administrator.

- Software layer: Levels adds food scoring on top of a sensor you buy separately.
- Human coach: Nutrisense adds a registered dietitian. You pay more for structure.
Many people learn most of what they need in a few weeks. Decide how long you will actually wear one before you buy a long subscription.
Who Should Talk to a Doctor Instead
- You take insulin or other glucose-lowering medication — OTC wellness CGMs are not designed for you.
- You suspect diabetes or prediabetes, or have symptoms like excessive thirst, fatigue, or unexplained weight change.
- You have a history of disordered eating; constant glucose tracking can fuel anxiety.
- You are pregnant or managing another medical condition.

Is a wellness CGM accurate enough without diabetes?▼
OTC wellness CGMs are useful for trends, not finger-stick precision. They read interstitial fluid with a lag, so a single number can differ from a blood draw — especially when glucose is changing fast. They are not diagnostic tools. If a reading worries you, see a clinician rather than self-diagnosing from an app.
