Irritable Bowel Syndrome Message Boards | Probably both stress and food

After you eliminate trigger foods from your diet and then re-introduce them again it can take several days before IBS symptoms reappear. The affect of various foods can be accumulative. For example, some foods act like prebiotics that can affect the flora in the colon. After a food is removed the population of a species of bacteria may decline to the point where the fermentation by-products it is producing that changes the GI motility is so low it has no effect. When you re-introduce that food it can take several days or even a couple of weeks before the population returns to a level where the amount of by-products produced is high enough to change the motility of the GI tract again.
