Patient Considerations

Active Lifestyle

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

Optional glucose alerts for low and high glucose levels. Trend arrows show the direction glucose is heading, with the rate of change. 

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

Lowest profile sensor and smallest adhesive (about the size of two stacked U.S pennies). 

Low profile and low maintenance sensor application.

Easy Insulin Dosing

Sensor trends can be used for dose adjustment.

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

No scanning required. Minute-by-minute readings are sent directly to the mobile app. 

Real-time data and alerts make dose adjustment easier.

Fewer Fingersticks
