Dexcom Stelo + Oura Ring: A Powerful New Duo for Managing Prediabetes

Imagine being able to see your blood sugar, sleep, stress, and activity levels all in one place. That’s the future that just arrived with the new integration between Dexcom Stelo, an over-the-counter continuous glucose monitor (CGM), and the Oura Ring, a sleek, science-backed wearable that tracks sleep, readiness, and recovery. This partnership gives people, especially those navigating prediabetes, a more complete, real-time view of their metabolic health.

If you’ve ever wished for more clarity around how your choices affect your blood sugar, or wondered how stress and poor sleep might be sabotaging your progress, this might just be the game-changer you’ve been waiting for.

In this article, we’ll explore:

• What the Dexcom Stelo and Oura Ring each do

• How this integration works

• Why it’s particularly valuable for people with prediabetes

• What a 360° health view actually means

• How to make the most of this new tech duo

What Is the Dexcom Stelo?

The Dexcom Stelo is a new kind of CGM: it’s designed specifically for people who don’t take insulin—like those with prediabetes, insulin resistance, or those simply looking to optimize their metabolic health. Unlike traditional CGMs that require a prescription, the Stelo is available over the counter, which means:

• No doctor visit required

• No insurance approval needed

• More accessibility for proactive health tracking

  
  

The Stelo tracks glucose levels in real time throughout the day and night, offering insights into how food, activity, and stress affect your blood sugar—even before it becomes a medical issue.

What Does the Oura Ring Do?

The Oura Ring is a smart wearable that tracks your:

• Sleep quality and cycles

• Readiness score (a combination of sleep, activity, and recovery)

• Heart rate variability (HRV), resting heart rate, and body temperature

• Activity and steps

• Respiratory rate and stress

It’s discreet, stylish, and backed by some of the best biometric algorithms available to consumers today. While it doesn't track glucose, it gives a detailed picture of your body's recovery and readiness.

What’s New About the Integration?

Dexcom and Oura recently announced that the Stelo CGM will now sync data with the Oura Ring app, giving users a combined view of:

• Glucose patterns

• Sleep trends

• Readiness and recovery data

• Activity and movement

In practical terms, this means Oura users can now see how things like poor sleep, exercise timing, or emotional stress affect their blood sugar—and vice versa. You can also log meal data, which shows up on a comprehensive timeline. The integration is seamless, intuitive, and makes your data easier to interpret.

You’ll be able to spot patterns like:

• Higher fasting glucose after a bad night’s sleep-- or logged meal data

• Blood sugar spikes following sedentary days

• Stabilized glucose after morning walks or improved sleep

Why This Matters for People With Prediabetes

Prediabetes affects more than 1 in 3 adults in the U.S., and most people don’t know they have it. The condition is silent—but the damage accumulates slowly over time.

The big problem?

Prediabetes isn’t just about what you eat. It’s also deeply influenced by:

• Sleep quality

• Stress levels

• Exercise habits

• Meal timing

• Hormonal fluctuations

Until now, tracking and connecting all those dots has been nearly impossible without juggling multiple apps, wearables, and spreadsheets. But with Stelo + Oura, it’s finally possible to see the bigger picture in real time.

Here’s how this combo helps:

1. Sleep and Blood Sugar: The Missing Link

Poor sleep—especially deep sleep—can:

• Raise cortisol (your stress hormone)

• Reduce insulin sensitivity

• Lead to higher fasting glucose

The Oura Ring already shows you how well you slept and gives a daily readiness score. Now, by adding Stelo’s glucose data, you can see directly how a short night or high-resting heart rate impacts your blood sugar. This makes it easier to connect lifestyle patterns to metabolic outcomes.

Example:

You notice your fasting glucose is consistently higher after nights where your Oura Ring says you had low deep sleep or a high heart rate. You now know sleep is a lever you can pull to improve blood sugar—without changing a thing about your diet.

2. Stress & Recovery: Not Just a Feeling

Chronic stress raises cortisol, which raises blood sugar—even if you’re eating perfectly. But stress is sneaky; we often don’t notice it building.

The Oura Ring tracks heart rate variability (HRV) and other recovery metrics to show when your nervous system is in fight-or-flight mode. Now, when paired with Stelo’s data, you can see how stressful days lead to higher glucose—even without a dietary change.

This empowers users to prioritize recovery tools like:

• Deep breathing

• Gentle walks

• Better sleep hygiene

• Mindfulness

3. Exercise Timing: Fine-Tuning for Blood Sugar Control

We know movement lowers blood sugar, but when and how intensely you move can make a difference. The Oura Ring tracks steps, movement, and heart rate response.

By combining that with CGM data, you can find your sweet spot for timing movement around meals or during stressful days.

Example:

You learn that a 10-minute walk right after dinner leads to a significantly smaller glucose spike—so you make it a nightly routine.

4. Meal Experimentation: Real-Time Feedback

One of the most powerful uses of a CGM is seeing how different foods affect your body.

But now, if you pair your glucose data with Oura insights, you can also consider:

• Whether poor sleep is amplifying a food’s effect

• Whether exercise earlier in the day helped blunt a spike

• Whether a high-carb meal after a sedentary day hits harder than usual

You’re not just seeing what spikes you—you’re learning why.

5. Behavior Change Through Insight, Not Guilt

Perhaps the most unappreciated benefit of combining wearables is empowered behavior change. When people see a clear connection between a habit and a result, they’re far more likely to change.

This is especially important for prediabetes, where people often feel confused or overwhelmed by mixed messages.

Stelo + Oura offers:

• Objective feedback, not guesswork

• Patterns over time, not single moments

• Insight instead of shame

It creates a feedback loop that says: You’re not broken—your body’s just responding to signals. Let’s tune those signals.

What a 360° View of Health Really Means

Here’s what you can expect when you combine these tools:

Metric	Dexcom Stelo	Oura Ring	Together
Glucose	✅ Real-time data	❌	Add metabolic insight
Sleep	❌	✅ Deep sleep, REM, efficiency	See glucose effects of poor sleep
Stress	❌	✅ HRV, resting HR, temp	Spot glucose increases due to stress
Movement	❌	✅ Steps, calorie burn, intensity	Understand activity’s impact on glucose
Recovery	❌	✅ Readiness score	Know when to rest or push harder

The true magic comes in the intersection of trends. One high glucose reading might not mean much, but when paired with low sleep, poor recovery, and no movement? That’s a pattern worth addressing.

How to Get Started

Here’s how you can use this integration effectively:

1. Wear the Stelo sensor (which lasts 15 days) and your Oura Ring consistently.

2. Link your accounts using the Oura app integration menu.

3. Track meals, stressors, and workouts as a logged item or tag in the Oura app.

4. Watch for trends, not isolated events.

5. Use the data to experiment:

   
   

   • Try cutting carbs at dinner and see how it impacts sleep + glucose

   • Test 10-minute walks after meals

   • Observe how social stress or travel affects your metrics

     
     

Knowledge Is Power—But Only If It’s Usable

The Dexcom–Oura partnership signals a shift in how we approach health. Instead of waiting for symptoms or a diagnosis, we now have tools that let us prevent problems before they start.

For people with prediabetes, where proactive, consistent habits can reverse the trajectory, this is especially powerful.

You don’t have to guess anymore. You don’t need to be perfect. You just need the right information, at the right time, in a way that actually makes sense.

And that’s what Stelo + Oura is finally delivering.

Want to Try It?

The Dexcom Stelo is now available online, no prescription required. And if you already wear an Oura Ring, the integration is just a few taps away.
