I've had Diarrhea problems for many years now, at least 5 or so. At least I think it's a problem but maybe it's the same for everyone but to be honest I'm too embarrassed to ever ask. I can be perfectly fine then it suddenly hits, when this happens there are usually about 3 stages where it gets worse and worse but in all my limit can be anywhere between 15 and 20 minutes. Usually this is fine but tonight it wasn't as it started just as I was getting onto a bus and 15 minutes later I had to get off the bus and find some bushes. I get the impression that most people have up to a hour or more when they first have the urge to go or maybe 15-20 minutes is normal? I usually get this several times a week but as I say usually I'm fine as a restroom in near by.
Could anyone give me their thoughts on what could cause such long serving problems? I have a good diet, not much junk etc
