Your sensor is designed to stay in place for its full wear duration. If it ever loosens early, it’s usually due to skin issues or bumping into things. Residual oils on the skin, sweat from intense movement, or the sensor getting knocked or tugged during daily activity might cause it to loosen.
If loosening happens or feels like it isn’t secure, we’re here to help.
First, refer to our helpful Adhesion Guides for troubleshooting. The guide can give you tips on applying and removing your sensor properly.
If your sensor falls off or if you Libre app displays a “Replace Sensor” message before the expected wear time ends, please reach out to Customer Service—we’re here to help.
