What Are Some Causes of Mucus Coming Out of Your Rectum?

Mucus in the stool is not necessarily a concern, as stool normally contains a small amount of mucus, according to Mayo Clinic. Larger amounts of mucus in the stool can be a sign of intestinal infections, ulcerative colitis, Crohn’s disease or cancer.

Mucus is produced by the body to protect and lubricate delicate body tissues and is therefore a normal component of the stool, says Healthline. If mucus in the stool is accompanied by diarrhea, it may be caused by an infection, whereas if it is accompanied by blood it may be due to irritable bowel syndrome or possibly cancer, says Mayo Clinic.
