What causes mucus from the rectum when you pass gas?

Mucus on stool: 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 ; probably a sigmoidoscopy should be considered, but a more extensive evaluation may be warranted.

Mucus from rectum: The most common thing to cause mucus from the rectum is hemorrhoids. We all have them. However, at age 74, you should see your physician for further evaluation as polyps or growths can also cause mucus. A digital rectal exam and anioscopy will be completed in the office and a colonoscopy recommended if you havent had one recently.
