Dexcom Stelo
Summary
This is a disposable, all-in-one CGM sensor integrated with Medtronic’s pump systems (e.g., MiniMed 780G). Typical wear time is 6 days, plus a 24-hour “grace period.” No routine fingersticks are required when the device is in closed-loop/SmartGuard mode.
FDA approved for ages 7+ on the back of the upper arm
MARD of ~9%
Dexcom Stelo is the first over-the-counter low-profile, all-in-one glucose sensor/transmitter. This sensor lasts for up to 15 days and sends real-time glucose readings to a compatible smartphone app. No finger pricks or scanning is needed.
*Recently FDA approved for people 18 years or older with type 2 diabetes. Expected availability is summer 2024.

Components
Sensor
Sensor uses a thin, flexible filament beneath the skin to continuously measure glucose every 5 minutes. Simple, one-step applicator makes insertion fast and easy.

Duration and Storage
6 Days
Sensors last 6 days, with a 24-hour grace period, and need about 2 hours to warm up. They work between 41°F – 104°F and should be stored between 36°F – 86°F. They are usually shipped in 1–3 month supplies, which is about 5–15 sensors at a time.
15 Days
Sensors last 15 days. They are purchased over the counter. Works at 50ºF – 108ºF

Patient Considerations
Active Lifestyle
Compact and integrated. Reducing bulk; compatibility with daily activities depends on the adhesive and body movement. Water-resistant up to 8 feet (2.4 m) for 30 minutes.
Waterproof when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device. This device is intended to help people with non-insulin requiring type 2 diabetes better understand their blood sugar numbers.
Avoiding Highs and Lows
SmartGuard closed-loop. Pump adjustments use sensor data continuously to reduce highs and lows.
Very limited alerts. This device does not provide alarms and alerts for high, low, and rise/fall rates. This device is intended to track and understand the effects of food on blood sugar for people with type 2 diabetes.
Comfort
Low profile. No overtape needed and one-hand insertion.
Low profile and low maintenance sensor application.
Easy Insulin Dosing
SmartGuard technology. When paired with the MiniMed 780G, it automatically adjusts basal and gives correction boluses based on sensor readings. In manual mode, glucose values can guide dosing decisions, but fingersticks are required for confirmation.
No options. Stelo is intended for use by people with type 2 diabetes who do not require insulin to manage their blood sugar levels.
Easy to Use
All-in-one. Eliminates the need for a separate transmitter, simplifying sensor changes (although more frequent due to the 6-day wear).
Real-time data and alerts make dose adjustment easier.
Fewer Fingersticks
Calibration is optional. Perfect if you like having that choice.
Factory-calibrated sensor. Finger sticks needed for backup only.
Privacy
Small and integrated, but visible on the back of the arm. No separate transmitter reduces the number of visible parts. Alerts and alarms can be adjusted for discretion.
Small sensor. Discreet and thin sensor that is easy to hide under clothing.
