A small amount of mucus in stool is most of the time nothing to worry about. Stool normally contains a small amount of mucus, a jelly-like substance that your intestines make to keep the lining of your colon moist and lubricated. But you should definitely talk to your doctor if you notice an increased amount of mucus in stool, especially if it begins happening regularly or if it's accompanied by bleeding or a change in bowel habits.
