Dexcom Stelo Review 2026: The Glucose Monitor Anyone Can Buy

No prescription. No finger pricks. Just real-time data about how food, sleep, and exercise affect your blood sugar — straight to your phone.

What is the Dexcom Stelo?

The Dexcom Stelo is a continuous glucose monitor (CGM) — a small wearable sensor that sticks to the back of your upper arm and tracks your blood sugar 24 hours a day, 7 days a week. It sends live readings straight to your smartphone every few minutes, showing you exactly how your glucose rises and falls throughout the day.

What makes the Stelo special in 2026? It’s the first CGM ever approved by the FDA for over-the-counter sale. That means no doctor’s visit, no prescription — you can order it directly on Amazon today and have it at your door within days.

Who is the Stelo for?

You don’t need to have diabetes to benefit from tracking your glucose. Here’s who the Dexcom Stelo is designed for:

• People with prediabetes who want to understand their metabolic health
• People with Type 2 diabetes who do not use insulin
• Anyone who wants to see how specific foods spike their blood sugar
• Athletes and fitness enthusiasts optimizing their nutrition and recovery
• People on GLP-1 medications like Ozempic or Metformin
• Anyone simply curious about their metabolic health

Important: The Stelo is NOT for people who use insulin. If you use insulin, ask your doctor about the prescription Dexcom G7 instead.

“Seeing my glucose spike after a bowl of white rice — and stay flat after brown rice — changed how I think about food forever.”

How does the Stelo work?

1

Apply the sensor

Press the applicator against the back of your upper arm. It inserts a hair-thin filament just under the skin in a split second. Most people feel nothing at all.

2

Pair with the Stelo app

Download the free Stelo app on iOS or Android, scan the sensor, and wait about 60 minutes for your first reading. The sensor connects automatically over Bluetooth.

3

See your glucose in real time

Your app shows a live graph updating every few minutes. You’ll see trend arrows showing whether your glucose is rising, falling, or stable — no finger pricks ever needed.

4

Log meals and learn your patterns

Use the AI photo meal logging to snap a picture of your food. The app shows you exactly how each meal spiked your glucose so you can make smarter choices over time.

5

Replace after 15 days

After 15 days, peel off the old sensor and apply a new one. If your sensor ever stops working early, Dexcom replaces it for free — no questions asked.

What does the Stelo app actually show you?

The app is one of the best parts of the Stelo experience. Here’s what you get:

• A live glucose graph that updates every few minutes, day and night
• Trend arrows — know if your blood sugar is rising fast, rising slowly, stable, or falling
• AI photo meal logging — just take a photo of your food and the app logs it automatically
• Daily Insights dashboard — personalized tips based on your glucose, activity, and sleep
• Weekly reports — see how your patterns change over time
• Apple Health & Oura Ring sync — connect all your health data in one place
• GenAI insights — ask the app questions about your glucose trends and get plain-English answers

Is it worth the price?

At around $89–$99 per month (2 sensors), the Stelo isn’t cheap. But think of it this way — one month of data can completely change how you think about food and your health for the rest of your life. Many users wear it for just 2–3 months to learn their personal metabolic patterns, then take breaks.

You can also buy a single 2-pack one time for $99 with no subscription commitment. That gives you 30 days of data to try it out risk-free.

The Stelo is HSA and FSA eligible, so if you have a health savings account, you can pay with pre-tax dollars and effectively get a 20–35% discount depending on your tax bracket.

Frequently asked questions

Do I really not need a prescription?

Correct. The Dexcom Stelo received FDA clearance as an over-the-counter device in March 2024. Anyone 18 or older who does not use insulin can buy it directly on Amazon with no doctor’s visit required.

Does it hurt to insert?

Almost everyone says no. The applicator inserts the sensor in a split second and the filament is thinner than a human hair. In Abbott’s own clinical studies, over 91% of users said insertion was completely painless.

Can I shower, swim, or exercise with it on?

Yes. The Stelo sensor is water-resistant and designed for everyday life including showers and workouts. Dexcom also sells adhesive cover patches separately if you want extra security during swimming.

Will my insurance cover it?

Most insurance plans do not cover the Stelo since it’s an OTC device. However, it is HSA and FSA eligible, which means you can use your health savings account funds to pay for it with pre-tax dollars.

What if my sensor stops working before 15 days?

Dexcom offers a free sensor replacement guarantee. If your biosensor stops working for any reason before the 15-day wear period is up, they will ship you a replacement at no cost through the app.

Is it available outside the US?

Currently the Stelo is only available in the United States. International availability is expected to expand in the coming years as Dexcom rolls out its OTC product line globally.
