Follow guidelines: Yellow or clear mucus is present in such little amounts that the naked eye would not notice it.When stool has visible mucus, it can be a sign of bacterial infections, anal fissures, a bowel obstruction, or IBD, IBS. Food allergies, such as those associated with nuts, lactose, or gluten, can cause mucus in the stool. People should contact a doctor if a noticeable increase in mucus or blood present.
