The Oura Ring and the Stelo continuous glucose monitor integrate to combine sleep, activity, and biometric data with continuous glucose readings, revealing how daily habits affect blood sugar. Stelo is a non-prescription Dexcom CGM sized about a quarter with tiny prongs, worn on the arm and delivering readings every 15 minutes for 15 days per sensor. Stelo is not intended for people on insulin. Sensors cost about two for $99 or $84/month with a subscription; Amazon lists two for $90.93. Users often wear sensors for two weeks to learn patterns, and the Stelo app shows current glucose and time-in-range. Single fasting glucose values are snapshots; A1C averages glucose over about 90 days.
The Oura fitness ring and the Stelo continuous glucose monitor (CGM) now connect. For the past month, I've been wearing the Oura Ring on a finger and the CGM on my arm. Together, they've given me a more complete picture of how sleep, stress, exercise and, of course, food affect blood sugar. I wrote about Stelo in January. What's new is that it now integrates with the Oura Ring, which I've recently started using for the first time.
Stelo Stelo is one of Dexcom's two CGMs. Unlike its prescription-only sibling, the G7, Stelo doesn't require a prescription, and it's not intended for people on insulin. It's about the size of a quarter with tiny prongs that go just under the skin and are essentially painless. Once applied, Stelo pairs with your phone and delivers glucose readings every 15 minutes. That's less frequent than prescription CGMs, but more than enough to show how food, activity, sleep and stress affect your glucose.
