I went to the toilet today and before flushing noticed that the end of one of my feces was slightly discoloured with a greenish aqua tinge. Then tonight I went again and the whole thing was tinged aquaish. Not a whole lot but noticeable without sticking your head in the bowl, lol. I'm 18 and anyway, I'm guessing this is because the day before I ate way too much sugar. Could this be a cause of the discolouration?
