Hi homer190376,
Exciting times ahead!!
A recent post mentioned that the diabetes specialist doctor is the best one to do a letter for you as GPs may charge you a stiff fee to do so. The main issues are :
having needles/syringes and fluid/medication (insulin) in your carry-on board gear and/or
wearing an insulin pump.
Pump manufactures warn that putting the pump through a luggage scanner may cause malfunctioning of the pump and void the pump's warranty.
The letter from my specialist has wording like; .."Removal of this pump from the wearer may prove lethal ..."
That seem to get the message across. I have to undergo a 'step-through' scan wearing my pump having removed my belt, shoes ect,
so either make sure your trousers/slacks etc fit well or have some string to keep them up until your belt is returned.
In my cargo luggage are sufficient insulin, needles/syringes, metho swabs, testing kit and testing strips/batteries/pump supplies to last at least 2 weeks longer than my planned trip.
In my carry-on luggage are sufficient insulin/needles/syringes. spare testing kit and strips/pump gear etc BUT NO METHO SWABS to last at least 2 weeks ( you never know how long cargo luggage can go missing and where). In carry-on luggage no flammables are allowed, so metho swabs are out. I usually take non-alcohol cleansing tissues if need be.
Timing of injections, meals etc. The best advice I ever received was from a drug rep. who was diabetic. He would wear two watches. ( and try his best to not look like a dodgy salesperson !!)
On setting out, he kept one watch on 'home time' and change the other watch with each change in time zone.
That way he could keep track of when he last gave his long acting insulin (staying on home time), and would take his short acting insulin when he was offered mealtime on the flight. He might have to take a meal at an airport if there was a long stopover between flights. Once at his destination, he would adjust his long-acting insulin accordingly: For a total 12 hour time difference breakfast became dinner time etc. 6 hours time difference meant advancing or go backwards 2 hours or so per day to get long-acting insulin in sync with the new time.
On the way back home; He would do the reverse. One watch staying on New England USA time etc.
I hope all the above plus the website info provided by @ urbanracer helps make your holiday even better !!
