I have celiac sprue and get a lot of orange mucus in my stool since I eat gluten anyway. The mucus is my body's way of trying to get rid of the poison--gluten.
It is probably just "quirk", but it never is wrong to query a doctor about a difference in bowel movements. Just to be safe call your doctor & if they ignore you as a nut case, call a GI.
God bless...
