I have Crohn's disease and have noticed my stools smell sweet? I am currently in remission and on no medication. I have also had no diet changes

Sweet stool. In general, a sweet odor to the stool is not worrisome. It could possibly be due to syrupy medications (which you say you are not taking) or due to not digesting sugars in the diet properly, which is unlikely if you are not symptomatic. I do not feel you need to see your doctor about this alone, but if it persists or you have new symptoms, bring it up at your next follow-up visit. Good luck.
