I have had type II for 8 years, and have been on both a insulin pump or injections for over 5 years. I always carry a written note from my healthcare provider regarding such with an active Rx for the insulin. I always tell the screening staff that I have Diabetes and I have a pump and other diabetic supplies with me. The secondary screening has never been that big of a deal for me. The only issue I have ever have is in Hong Kong. They always for some reason require me to do a finger stick to test my blood sugar. I also make sure that the letter from the physician outlines all my other medications that I take and carry the pharmacy RX from each at all times. This has always seemed to calm the boat in every port so to speak, make sure that it includes insulin pump supplies, if you are traveling internationally - at least that is what I have found.
