Your CGM sensor is designed for you to continue living your normal day-to-day life. You shouldn't have any issues with TSA and can go through airport security with your sensor on.
You can wear your sensor when going through walk-through metal detectors and Advanced Imaging Technology body scanners. You can also request hand-wanding, pat-downs, visual inspections, as desired. Let the Security Officer know the sensor can’t be removed because it’s inserted under the skin.
