If she already knows this happens regularly, then whether she wakes him up beforehand or tells him afterwards, doesn’t mean she hadn’t let him know at some point?
Once she realizes that this happens regularly, she should tell him “you pooped the last few days before waking up. Let me wake you up beforehand so you make it to the toilet in time, also make an appointment at your doctor”. Maybe that’s what happened and he just omitted it because it isn’t relevant for the diagnosis. We’ll never know.
