My dad is staying with me for a month, the toilet is next to my room and I am a very light sleeper. I can hear him getting up to urinate probably around 7-8 times in the night. The last time he went twice in a half hour period. I know he's had PSA testing a while back and was also tested for diabetes at the time which was negative. Quite apart from the negative effect on my sleep this can't be normal or sustainable, has anyone got any experiences to share as I think I need to talk to him about this. I don't think it's as frequent during the day but I probably wouldn't notice it as much.
