TD1 help abroad

I would
- change to your backup pens. I assume these are profiled pens. If not change your pens and insulin cartridges
- if you have a sick day plan agreed, adopt this
- if you can, test your ketones
- set an alarm in 2to 3 hours to test again
- don’t “rage bolus” (stacks too much bolus insulin)
- if your BG and ketones keep rising, visit a hospital

Being away from home means quite a few things are different such as knowing what was in the food (and beer?) you ate.

Hmm, some possibilities
1) As you said, a bad pen(s). Does the rise coincide with a change in pens? Have you checked to make sure the vial inside isn't cracked? If it's a pen then it's unlikely to be both, so examine them both very carefully to find the culprit.
2) Travel stress or you're coming down with a bug caught on the plane.
3) Honeymoon end??? A bit out there, since you're T1 and have been diagnosed 3 years, but if you were still producing insulin then this production could be tapering off.
4) Your profile doesn't say whether you're male or female. Pregnancy ! (OK, I'm really stretching here).

I'd be cautious about increasing long acting till you've checked that it's not pen issues. Running a bit high won't kill you, having a major hypo might. Are you alone or are you travelling with friends or family who can rescue you if you have an unexpected bad hypo?

Hopefully your nurse will get in contact to advise on doses. All I can really recommend is test, test, test.

Make sure you've got a card with

Good luck.
