stool odor
Foul smelling stool may be caused by poor diet and digestion. Eating fried, greasy foods, processed foods, refined sugar and excessive alcohol consumption is the primary cause of foul-smelling stools. It may also be due to an overgrowth of bacteria â bacteria produces hydrogren sulfide (rotten egg smell), ammonia or sulfur odors.
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.
