Welcome to the official web site of the Alliance of Congenital Diaphragmatic Hernia Organizations (ACDHO), an International group of professional charity and research organizations working together to better serve babies and families affected by Congenital Diaphragmatic Hernia.
A diaphragmatic hernia is a birth defect
(an abnormality that occurs before birth) that develops as a fetus is
forming in the mother's uterus. A congenital diaphragmatic hernia (CDH) occurs when the
diaphragm does not form properly. The diaphragm is a thin sheet of
muscle that separates the abdomen from the chest. The diaphragm is an
important muscle for breathing. When there is an opening in the
diaphragm, organs that are normally in the abdomen can be pushed
(herniated) through the opening into the chest. Currently little is
known about why this birth defect occurs.

Diaphragmatic Hernia and resources for support and research.
