When working full time, I only mentioned it casually, but I rarely had specific bathroom issues. I preferred the private bathroom rather than the busy one...only because I liked to brush my teeth in private and not be rushed,
The few times I had to use the bathroom because I was flaring, I only explained it to my immediate workers who would be affected by my absence.
At this point I don't have a boss...all my hair clients know I have UC and other health stuff and we schedule accordingly. I've warned some before I come that I might have to run to the bathroom, but it's not happened actually.
So, in truth....unless you have issues, I'd mention it only if you have to, but stick to your med regimen and treat anything as early as possible.
Everyone has had gut invaders of one sort or another, and it doesn't mean you won't pick that up as well...in otherwords, you'll be "normal". It's difficult to separate the two, but you might be impacted worse as a result because of it.
