When you have inflammatory bowel disease (IBD), finding a bathroom while traveling can be tricky. You sometimes need to use the bathroom in a hurry, so when traveling in a strange city or in a strange country, you really need to be prepared.
In some countries, you need to pay to use public toilets. Be sure to keep some change on you at all times. If you're a fan of toilet paper (and who isn't?), you'll want to have some with you if you're traveling to a country that has squat toilets. Antibacterial hand gel is a good idea no matter where you're traveling.
Flushing mechanisms may be located on the floor in the form of a pedal, or above in the form of a chain that you pull. Be sure to find out how the toilet works before it becomes a problem.
If you don't speak the language, you'll want to at least be able to ask where the nearest toilet is located.
