A bit of a gross topic i know, but even doctors admit that your stool is a good indicator of health. Mine are consistently semi diarrhea, generally no shape but also often one of the following:
. Completely yellow
. Semi diarrhea with undigested food
. Pellet like shape
During recovery periods my stool has returned to how you would expect for a healthy 20 year old. Well formed, normal brown color. I have noticed that when i feel particularly bad the yellow stools occur.
