What are your flares like?
I feel like extreme emotional and psychological stress brought on my Crohn's this past year (I'm currently being diagnosed). I was in an abusive relationship, changed countries three times and jobs three times. My Crohn's really flared up (arthritis attacks, erythema nodosum, weight loss) when I was living briefly in Hong Kong and going through post break up emotional and psychological crap, therapy etc. And I don't think the climate helped at all either - horribly hot and and humid outside, freezing A/C inside so my body was continuously stressed out as well.
However, the past five years I've had some digestion issues but I just put it down to lactose intolerance and avoided dairy, and cut out caffeine and cut my wheat intake in half. That seemed to work for me until the past year when I began my flare.
I've been going into remission this week with a new drug 5-ASA and starting to break away from the IBD diet that I was experimenting with the past 3 weeks. I don't know if certain foods bring on a flare for me, but I decided to go easy on my digestive system while the inflammation in my large intestines heals by eating lots of cooked food such as home made soups, cooked veg, meat, egg, and rice noodles (not on the IBD diet however). For the past month, I've cut out wheat, corn, soy, barley, refined sugar, and all the dairy with lactose (I have still been eating aged cheddar and parmesan though since they don't have lactose) but I'm not sure if any of these were the triggers or directly responsible for causing the inflammation. I really can't pinpoint any of this on my diet. I'm sure refined sugar hasn't helped me at all this past year as it feeds inflammation but I don't think it caused the flare for instance. I think some foods don't "help" the situation but then again, everybody's body is different and reacts differently. I hope that once the inflammation is gone I can go back to eating my low gluten, low dairy diet because I felt that that was working for me for years.
Hope you find my experience helpful!
