I have traveled a lot with my pump and rarely had any problem. I NEVER take it off! I tell them I can’t. I was told that putting my pump through the X-ray could cause damage to the pump— so I never wanted to find out!
I have found that INSULIN is a pretty international word-- so I just repeat that over and over again And as others said most security people know what the pump is by now-- even in countries where it is not so common. Sometimes I have noticed that they seem really excited to recognize the pump (probably cause they were taught about it in training, but rarely see it here in Eastern Europe). Usually they prepare me for a “pat-down” search, but since my Cozmo doesn’t even set off the medical detector, they usually just wave me through.
I often try to have my infusion set on my stomach when I travel-- once when a security guard was insistant that I had to take it off, I just showed him my stomach and that I was attached to this little machine and that was enough info to get him to just wave me through
I also have a statement from my doctor, but I never have had to show it.
OH, but I HIGHLY recommend ordering a diabetic meal on international flights! It’s usually not low carb, but you get it served first and it prepared separately so you usually have fresher salad and some fruit instead of dessert. Also, especially when I’ve traveling alone, I like that the flight attendants know that I have diabetes…
