Yes, sorry; I should have mentioned that in my original post: it causes a threefold increase in individuals who are already at risk genetically, but does not appear to directly cause Crohns. And yes, I also found it interesting that there was no apparent correlation between UC and the pill. (When I read the article headline, I was of course all ready to jump at that as a potential trigger in my case, since I developed acute UC at age 26, after I'd been taking the pill for a few years.). There are some in medical profession who now feel that UC and Crohns are essentially the same disease, but with different presentations. They might be, but this study appears to offer further proof at how differently the two manifest.
