There are all sorts of medical conditions or even just metabolisms that make some people need to go for one or the other really often - as a candidate, it can also be really scary/embarrassing to interrupt your interviewer to ask to take care of these. And, interviewers generally don't communicate/schedule these between each other to ensure it gets handled according to your schedule, even if you only need a couple breaks.

It's far better to just have everyone ask; the candidate can politely refuse if not needed, and everything continues on normally.
