Travel and Airport Security Protocols

Flying with CGMs

Traveling with a Continuous Glucose Monitor requires some preparation but is generally straightforward.

TSA Guidelines (US)

What's Allowed

• CGM sensors can be worn through security
• Carry supplies in carry-on luggage
• Receivers/phones are standard electronics

Screening Options

• Walk-through metal detectors: Safe for all CGMs
• Millimeter wave scanners (body scanners): Generally safe, but some manufacturers recommend avoiding
• Pat-down: Always an option if preferred

Documentation

• Carry a letter from your doctor
• Keep supplies in original packaging when possible
• TSA notification cards are available (optional)

X-Ray Concerns

Carry-On X-Ray

• CGM supplies can go through carry-on X-ray
• Sensors in original packaging are fine

Checked Luggage

• Avoid putting sensors in checked bags if possible
• Extreme X-ray exposure in cargo holds is a concern for some devices

International Travel Tips

• Research destination country regulations
• Carry extra supplies (sensors, transmitters)
• Know the local word for "diabetes" and "insulin"
• Carry prescriptions for all supplies

Altitude and Pressure Considerations

• CGMs work normally at altitude
• Pressurized cabins don't affect function
• Some users report temporary accuracy variations during flight
