Diaphragmatic hernia is a hole in the diaphragm that is present at birth. The diaphragm is the muscle between the chest and abdomen. Organs in the abdomen move through the hernia to the chest. They can push up against the lungs.
This problem is caused when the diaphragm does not form normally in the fetus. It is not clear why this happens. It may be due to genes or the environment.

Problems in the mother that may raise the risk are:
Symptoms may appear after birth or happen later. They may be:
The diagnosis is often made before birth with an ultrasound.
In others, the doctor will ask about your child's symptoms a health history. A physical exam will be done. Images of the chest will be needed. This can be done with a chest x-ray.
Treatment depends on how severe the condition is. Emergency care may be needed after the baby is born. It may include close monitoring and help with breathing and blood flow.
Surgery will be needed when the baby is well enough. It will move the organs back into place and repair the hole.
There are no known guidelines to prevent this problem.
