fecal impaction

(FEE-kul im-PAK-shun)
A mass of dry, hard stool that cannot pass out of the colon or rectum.

Signs and symptoms may include being unable to have a bowel movement, pain in the abdomen or back, problems urinating, and nausea and vomiting. Fecal impaction may also cause problems with circulation, the heart, or breathing.
