A lot of people change their diet so that their intestines don't have to work so hard.
Foods to avoid would be red/dark meat, whole grains, uncooked vegetables, fruit skins/seeds, fried foods, onions, spices, gassy foods (cauliflower, cabbage, brussel sprouts, beans).
Foods to eat would be well-cooked veggies (that you can mash with a fork), white meats, fish, salad greens, white bread, yogurt (watch out for fruit seeds), pasta, rice, soup.
Some even go so far as a liquid diet for a few days, I've tried that myself and it seems to help.
I'd also suggest that you use Omega 3's and probiotics.
Hope you do well in your exams, and that you feel better soon.
CD since July 2007 - prenatal vitamins + extra vit. D, vit. C and iron, fish/flax oil, probiotics
Following excellent Omega-3 diet as per James Scala's 'The New Eating Right for the Bad Gut' - got me out of a flare.
