Causes of Hirschsprung Disease
Hirschsprung (pronounced HURSH-sprung) Disease (HD), is a disease of the * large intestine, which usually occurs in children.
Hirschsprung Disease develops before a child is born. Normally, * nerve cells grow in the baby's intestine soon after the baby begins to grow in the womb. These nerve cells grow down from the top of the intestine all the way to the * anus. With Hirschsprung Disease, the nerve cells stop growing before they reach the end.
No one knows why the nerve cells stop growing. But they do know that it's not the mother's fault. Hirschsprung Disease isn't caused by anything the mother did while she was pregnant.
Some children with Hirschsprung Disease have other health problems, such as Down syndrome and other rare disorders.
