Welcome to

The website is being developed to help identify and provide support for individuals experiencing a common, but unspoken condition - Toilet anxiety. We hope to finalize the website (including free psychological treatment for paruresis and parcopresis) soon.

We are currently looking for participants in research related to toilet anxiety. If you are interested, please view our list of studies.

PLEASE NOTE: This website and its contents relates to toilet anxiety experienced by adolescents and adults. Children who have bowel and/or bladder concerns and anxiety relating to the use of toilets, are recommended to speak with their paediatrician and seek advice from a developmental/child psychologist.


What is Toilet anxiety?

Toilet anxiety, or toilet phobia, is a term used to describe a number of issues related to using the toilet. It is a type of anxiety condition in which the sufferer may experience concerns and fears about one or more of the following:

  • Being unable to urinate or defecate
  • Using a public toilet
  • Being too far from a toilet
  • Having an accident in public
  • Other people being able to hear or see you use the toilet
  • The cleanliness of public toilets
  • Being confined in a small space

This website is being developed by Dr Simon Knowles, a Clinical Psychologist and Senior Lecturer at Swinburne University of Technology, Melbourne Australia. Simon specializes in conducting research and helping individuals who experience gastroenterological conditions.
