Cruise ship/Flight attendant

Well i have been thinking about my future career.. I really like the sounds of working on a cruise ship! I think it would be an amazing job.. That or a flight attendant I really want to see the world!
But can I still choose these career paths if I have diabetes??
I've read things saying you need a medical examination... Does anyone know any requirements for these jobs?
Or if you can still apply even if you have diabetes?

Also does anyone know a list of jobs you can’t do if you have diabetes?

Hmmm. I'm afraid I can't be of too much help, but military ship/flight staff unfortunately are not accepted with diabetes. Maybe for commercial service the rules are different, but the only way to know for sure is to call companies and ask.
