Hello
@Lea Fowler Many of us travel via airports so the staff at airports understand well about not putting us through the body scanners, we normally get a pat down, you can carry a letter from your GP explaining the patient's T1d status if you wish but in my 14 years travelling 2-3 times a year I have never been asked for it.
My best advice is to take x3 of what you think you will need, check online for local pharmacies in case you have an issue with insulin overseas, get yourself a Frio case to carry insulin in and to keep it cool. I keep all my medical supplies in hand luggage in case the luggage goes missing.
In regards to management of food - are you using a sensor ? Try to keep carbs low if your new to carb counting and unsure as it reduces the margin for error and download carb & cals on your phone as it shows carb content of food which helps understand it more but you should also speak to your diabetic nurse to get some guidance on this too.
Take care with the exercise and heat abroad both these affect control and we can easily go low. Try to run slightly higher if you can to avoid the drop, get some tegaderm plasters to cover sensors for swimming to save them falling off too.
Carry glucose everywhere so it is easily accessible - so a shoulder bag with glucogel and jelly babies, next to bed and on the body at all times.
Holidays should be a time of relaxation but the change in temperature, routine, sleep, exercise, different food can be tricky so with a bit of support off your team and guidance it shouldn't be a huge issue, try to relax as holidays are vital and shouldn't feel stressful but being prepared for all situations will help, best wishes J
