I once drank one of those "sports drinks" simply because I decided to go for a brisk walk! ....I don't particularly care for exercise, but of course I realize its important, and so I was flabbergasted when I got the most awful stabbing pains in my stomach, which was the first and last time I have ever experienced any kind of real pain with UC! so that, then and there confirmed that those drinks aren't that good for people with UC.
