Congenital diaphragmatic hernia (CDH) is the lack of development before birth of all or part of the diaphragm, which normally separates the organs in the abdomen from those in the chest cavity.[1][2] It can range in severity from a thinned area in the diaphragm to its complete absence.[2] CDH may allow the stomach and intestines to move into the chest cavity, crowding the heart and lungs. This can then lead to underdevelopment of the lungs (pulmonary hypoplasia), potentially causing life-threatening complications.[2] CDH has many different causes and occurs with other malformations in some cases.[1][2] Treatment options depend on the severity of the defect.
