I have mucous in my stool. what could that mean?

Stool mucus or more?: Mucus discharge occurs in up to 50% of patients with irritable bowel syndrome, with or without pain. Mucus may also be produced in response to partial obstruction, chronic constipation, rectal dysfunction, infection, & even from secretory villous tumors of the rectum. At the very least stool studies should help address if mucus white bits you're seeing are "worms" (pinworms, etc.) so rx can begin.
