CGMs Without Diabetes: Stelo and Lingo Explained
Humanic Blue’s Longevity365 explainer: A continuous glucose sensor measures glucose in fluid beneath the skin and sends readings to an app. This explainer uses Stelo and Lingo to show what those readings, feedback scores and eligibility rules mean.
Explore the productsLiving longer and better is a reason people explore health data. Continuous glucose monitors, or CGMs, measure glucose in fluid between cells; their readings are not identical to a finger-prick blood value at every moment.
01 / Our approach
How did we evaluate these products and services?
We compared the existing Stelo and Lingo offerings, company-described wear duration and phone access. Stelo’s expanded FDA clearance and its current adult retail wording are described separately.
Fasting Insulin vs. Fasting Glucose: evidence and sources02 / The takeaways
What did the source evidence show?
- Stelo describes sensors lasting up to fifteen days; Lingo describes up to fourteen days. Actual wear can be shorter.
- Lingo’s current US offer supports both iPhone and Android. Its app adds food and activity logging and Lingo Count feedback.
- A glucose graph does not establish that a person without diabetes will live longer by changing every rise.
What would a glucose rise tell you, and what would it leave unexplained?
The products and services
What is distinct about each product or service?
Stelo and Lingo are two examples used to explain this category. Their order is not a ranking or a recommendation.
The matrix compares the named formats and access arrangements, rather than awarding a clinical winner.
Product 01 / 02
Dexcom Stelo
Service or device formatOver-the-counter glucose sensor and app
Dexcom describes a wearable sensor connected to a compatible smart-device app. FDA describes up to fifteen days of sensor wear and trend displays every fifteen minutes. The checked retail site continues to describe adult use without insulin.
FDA expanded clearance in June 2026 to non-insulin users aged two and older, with adult supervision for children. That expansion is distinct from the adult retail offer. FDA excludes problematic low blood glucose and dialysis; a history of disordered eating needs clinician discussion.
Product 02 / 02
Abbott Lingo
Service or device formatAdult glucose sensor and habit-feedback app
Abbott describes an upper-arm sensor sending glucose readings every minute to an iPhone or Android app. The company advertises up to fourteen days of wear, with food and activity logs, Lingo Count and habit insights.
Current US labeling specifies adults eighteen and older who do not use insulin. It is not for diagnosing diseases, including diabetes. Abbott advises clinician discussion for a history of eating disorders.
Abbott describes Lingo Count as its numerical summary of selected glucose rises, with larger and longer rises contributing higher values. It is a company-defined score rather than a diagnosis.
How might constant feedback affect someone’s relationship with food?
Reader Questions
A few questions to consider while reading the evidence.
- Which distinction changes what you would expect from this service?
- What would the result or program leave for a clinician to explain?
Extra Insights & Sources
For readers who want the evidence and comparison details behind this guide.
Regulatory context outside the purchasing comparison
Abbott Libre Rio: FDA cleared Libre Rio in June2024 for non-insulin-using adults. Abbott describes its intended commercial audience as adults with type2 diabetes, which differs from this guide’s non-diabetic focus. A current ordering route was not established in the checked official Abbott product and where-to-buy pages. Clearance alone is not proof of current sale.
