Dexcom G7 vs Stelo: Which Continuous Glucose Monitor Is Right for You?
Continuous glucose monitors (CGMs) have transformed diabetes management, and Dexcom leads the market with two impressive options: the Dexcom G7 and the newer Stelo. While both devices track your glucose levels in real time, they serve different audiences and come with distinct features. Understanding the differences can help you make the smartest choice for your health.
What Is the Dexcom G7?
The Dexcom G7 is a prescription-based CGM designed for people with Type 1 or Type 2 diabetes who use insulin. It offers:
- 10-day wear plus a 12-hour grace period
- Real-time alerts and alarms for high and low glucose events
- Integration with insulin pumps and automated insulin delivery (AID) systems
- Compatibility with Apple Health, Dexcom Clarity, and other diabetes management apps
- Coverage through most insurance plans and Medicare for eligible patients
The G7 is the gold standard for people who need tight glucose control and rely on insulin therapy. Its customizable alert system makes it especially valuable for preventing dangerous hypoglycemic episodes.
What Is the Stelo?
The Stelo is Dexcom's first over-the-counter CGM, approved by the FDA in 2024 for adults who do not use insulin. This makes it a groundbreaking option for:
- People with Type 2 diabetes managing with diet, exercise, or non-insulin medications
- Prediabetic individuals wanting to monitor glucose trends
- Health-conscious adults curious about how food and lifestyle affect blood sugar
Stelo features a 15-day sensor wear, making it the longest-wearing Dexcom option available. Because it is OTC, no prescription is needed, and it can be purchased directly online or at select pharmacies. However, it does not include urgent low glucose alerts, as it is not intended for insulin users.
Key Differences at a Glance
| Feature | Dexcom G7 | Stelo |
|---|---|---|
| Prescription Required | Yes | No |
| Sensor Wear | 10 days + 12-hr grace | 15 days |
| Urgent Low Alerts | Yes | No |
| Insulin User Compatible | Yes | Not recommended |
| Insurance Coverage | Often covered | Typically out-of-pocket |
| Target User | T1D & insulin-using T2D | Non-insulin T2D & prediabetes |
Which One Should You Choose?
The decision largely comes down to your treatment plan and health goals:
- If you use insulin or have Type 1 diabetes, the Dexcom G7 is the clear choice. Its alarm system and pump integration could be life-saving.
- If you manage Type 2 diabetes without insulin or want to understand your glucose patterns without a prescription, Stelo offers a convenient, accessible entry point into CGM technology.
Cost is another factor. The G7 may be covered by insurance, while Stelo is typically purchased out of pocket. Always check your plan's formulary before deciding.
