If it is IBD, then yes, it could cause all the things you mentioned.
Re the eye inflammation. I have uveitis, which is an autoimmune eye condition related to Crohn's. But that got diagnosed because I did have obvious redness and pain. If you get the blurriness again you should go to an opthalmologist and get your eyes checked out: it's a 5-minute test to determine if there's inflammation in the eyes or not.
Dx Crohn's in June 2000. (Yay )
Tried: 5-ASAs, azathioprine, 6MP, Remicade, methotrexate, Humira, diets.
