I also wish that I'd been told what kind of Crohn's I had (in my case stricturing as opposed to inflammatory or fistulizing, although I realise there can be some crossover) and which parts of my bowel were affected when I was first diagnosed. It would have helped me understand that my symptoms were different (and not necessarily less severe) from other people with Crohn's sooner and also the particular risks that I faced with the disease.
It sounds obvious, I think, but at 17 no one said anything much to me other than that I had Crohn's. With hindsight I'd have appreciated it if someone had said "You have lots of strictures and they're throughout your jejunum and ileum and this is already a more complex presentation of Crohn's."
Not that I'm trying to contradict my earlier point about each of us requiring very good treatment whatever 'mild', 'moderate' or 'severe' classification we're given, because I think that's really important especially as it seems these classifications aren't terribly useful with 'mild' cases progressing to 'severe' and that being more likely to happen with less aggressive/appropriate treatment.
But I don't think that I understood that these other complications that I heard of were not signs of more severe disease but rather a different type of Crohn's. And I certainly felt that I was less deserving of intensive monitoring and escalation of treatment and even just plain old concern, not just because my doctor (who was a BAD doctor) would say things like 'you're not sick enough for enteral nutrition, that's only for the sickest patients' WRONG or 'you have Crohn's, you'd expect to be in pain, you're on medication so I don't want to hear about it, there are sicker patients than you' ALSO LARGELY WRONG!! but also because I saw thinner patients at the hospital and I'd put on weight on steroids, because people told me of their friends and relatives who had been hospitalized with Crohn's and I never had been.
I think information like that would hopefully have allowed me to put my Crohn's into perspective alongside the experience of others and those second and third-hand experiences that were shared with me and to not feel like I should just soldier on. I think it would at least have allowed me to question the choice of budesonide and pentasa for my treatment, although it is so much easier to know that now with all the information available to us on the internet.
That turned into a long story about me but, yes, what I really wish I'd known was that it is important to understand the presentation of your individual type of Crohn's and understanding how different the manifestations of Crohn's can be.
