I do not believe UC or Pouchitis are related to diet. I was diagnosed with Colitis in my teens at a time when I was not a big eater at all or had experience any real stress!
Since my JPouch surgery in 2006 I’ve not had any issues with urgency and have a good quality of life. If I’m being honest my diet has not always been the best since the surgery as I am just so happy to be able to comfortably eat everything and anything. However this thankfully has not had a negative effect on the pouch....that is until this current bout of Pouchitis.
Nobody seems sure why why this occurs and I think it’s different for everyone but I would mention that we recently found out that my Grandfather suffered from Colitis during his life further confirming the original genetic link.
