Going through airport security can be daunting with or without diabetes. Fortunately, there are government endorsed guidelines when dealing with CGMs and insulin pumps.

CGMs can go through metal detectors in much the same way as insulin pumps, but the airport x-rays can damage the devices. It is important to alert the airport staff of your medical alert and ask for a physical check of person and luggage. CGMs and pumps must not be removed even when going through security.

You should carry a letter from your doctor detailing your medical condition, your need for medication, blood glucose checking or monitoring, CGMs and pumps. Making several copies of this letter is advised as it will be needed at customs. Carrying additional photographic identification is also recommended, along with your NDSS card.

When flying it is recommended you take your blood glucose monitor aboard so you can check perform a check if your symptoms don’t match your CGM reading.
