The CGM device is minimally invasive. Each device has a filament the size of a kitten's whisker that sits just below the skin. You put a new sensor on every 10 days and remove the old one (it's like peeling off a band-aid).
The Dexcom auto applicator was designed for easier, more consistent sensor insertions. According to a survey of Dexcom users, 84% reported that the initial sensor insertion was painless, and 100% reported that the applicator was easy to use.
If you feel pain or discomfort
Try changing the placement of your next sensor to another part of your body. We recommend not using the same location twice consecutively but changing the location with every new sensor.
If pain or discomfort occurs and you take your sensor off early, please contact firstname.lastname@example.org. You can stay on track by putting on one of the sensors in your package vs. waiting for the arrival of the replacement.
