No need to go running off to the bathroom quite yet though, as this usually only happens when the poor, unfortunate patient is physically unable to pee, such as in the case of some cancers or following surgery. The good news is that most people will usually wet themselves before things get to this stage, making it probably the only instance in which peeing your pants is the best possible outcome.Although your abdomen is unlikely to go pop on long car journeys, it is still not advisable to hold it in too much as this can lead to infection. Not meaning to sound like your mum or anything, but it's always best to "have a try" anyway.
