Encopresis

Encopresis, also known as functional fecal incontinence or soiling, is when children pass stool (poop) into their underwear, in most cases accidentally. It occurs in children 4 years of age and older who have been toilet trained. The condition is more common in boys than girls. It affects 1% to 4% of children who are 4 years old, and the frequency of this condition decreases with older age.
