This had been a hard question for me too. I've never had bleeding or weight lose. I have learned, even though I'm in remission that I still have what I call "mini-flares". Just days when my stools are watery and I lack energy. Usually lasts a day or two and then I'm okay. I won't call my GI unless it lasts at least a week or other manifestations appear.
