Dexcom Stelo

Stelo makes continuous glucose information accessible without a US prescription, but its appeal depends on who is wearing it. Our selection here is for adults who do not use insulin and do not have problematic hypoglycaemia. For that group, seeing a sequence of readings can provide more context than an isolated measurement. It is not a substitute for an insulin-management CGM with the appropriate alarms.

The practical strength is a clearly defined self-service workflow: apply the upper-arm sensor, connect a compatible phone and examine patterns over a stated wear period of up to 15 days. The useful question is whether those observations help the wearer discuss a specific issue or make a sustainable change, rather than whether every meal produces a perfectly flat graph.

There is a labelling difference to resolve: FDA expanded Stelo clearance to ages two and over in June 2026, while the current consumer page still states 18+. This selection is deliberately for adults. Families should obtain the current paediatric instructions and caregiver workflow.
