The substance that is coming out of your rectum is most likely mucous. It's usually a bit lighter in color than normal stool, but it can still smell pretty foul, or it may have no odor at all. Best of luck to you. If you have questions, skip the nurse and ask someone who has a colostomy, unless it's an emergency, of course.
