Although unfortunate, this is a perfect example of the indiscriminate nature of IBD. It strikes anyone, no matter what sort of diet you follow, no matter how much you do or don’t drink or smoke, no matter how much gluten you do or don’t eat. (IMHO, though, gluten has nothing to do with IBD, except for being a trigger food for some people. I don’t buy into the whole “gluten is evil” sensationalism that is flowing around in the media at the current time.)
And I think it’s a really important thing for people to realise and understand - there is NOTHING you have done wrong, and there is nothing you could have done to stop it. Life is a bitch sometimes and shit happens, even if you take the best precautions.
I don’t think it’s a karma thing, or like, you’ve done something wrong, it’s just an unfortunate set of factors that have led to you being diagnosed with IBD. Since there is no known single cause, that’s why I say a “set of factors”, because my gastroenterologist explained it kind of like being in the wrong place at the wrong time, with the wrong environmental factors there to set off a potential genetic pre-disposition to IBD.
So, to answer your question, you did nothing wrong. And it is NOT your fault. :) x
