Hetty is right to point out that it's very likely that your sleep quality has changed. I would say a couple of visits is par for the course, but see the GP if worried. Research studies on sleep in 'older' people indicate that wakeful periods increase in number and duration, and if you are awake, you will naturally think of needing a visit to the loo. Discomfort and pain due to conditions such as arthritis, plays a part in the likelihood of waking. It's something that exercises me (literally): it's not to solely to pee though. I have suffered from IBS since my early teens and have at least 4 visits to the loo every night, sometimes many more. It's exhausting! However, all has been investigated and nothing sinister found, so I just put up with it. Added to that, I have hip pain which stops me from getting back to sleep. Not for wimps, this ageing business, but better than the alternative!
