Encopresis (soiling) is a condition that causes a child beyond the age of toilet training to have bowel movements (poop) in his or her underwear.

More to Know

Kids with encopresis (en-kuh-PREE-sis) have a bowel problem that dulls the normal urge to go to the bathroom — and they can't control the accidents that typically follow.

Most encopresis cases are due to functional constipation — that is, constipation that has no medical cause. In constipation, the stool becomes hard, dry, and painful to pass. These large stools stretch out the rectum and colon (parts of the bowel) and decrease a child's urge to have a bowel movement (BM). Eventually, liquid stool leaks around a large piece of hard stool lodged in the rectum.
