What is (are) Hirschsprung's disease ?
Hirschsprung disease is a disease of the large intestine or colon. People with this disease do not have the nerve cells in the intestine required to expel stools from the body normally.

The symptoms may vary with age, but often involve constipation and/or obstruction of the bowel.
