Hi Kata,
I agree with Axl advice, if you are having any concerns, then contact you stoma nurse, that is afterall what they are there for..and they don't bite!
Also have you looked up St. Marks 'pouch care nurses', apparently they are some of the best in the world and St Marks Hospital is where the J-Pouch surgery was pioneered by Prof Nicholls et al.
Some support sites/contact in the UK
St Marks Hospital pouch care website https://www.stmarkshospital.nhs.uk/services-a-z/stoma-care/
Get in touch with them they take patients from anywhere in the UK, St Marks is the J-Pouch specialist center. Also on that first landing page there is an email address that they respond to very quickly and best thing about it is, you can email them from anywhere in the world, i.e. you dont have to be a UK resident or be registered on the NHS or have ever been. It's a wonderful service, please check it out.
