Some people need to go to the toilet frequently.
This can be so disturbing that they can never be too far away from a toilet and it interrupts their sleep and what activities they can participate in.
Going to the toilet up to eight times per 24 hours is normal.
There are a number of different causes including urine infection, overactive bladder, incontinence and interstitial cystitis. There are multiple factors that can influence how often someone has to pass urine. It may relate to how much the bladder can hold, how well the bladder empties or the volume of urine produced.
There is a map available of all the public toilets in Australia. www.toiletmap.gov.au
