How does a diaphragmatic hernia affect the body?

A diaphragmatic hernia affects the body by allowing stomach organs to break through a gap in the diaphragm and affect the heart and lungs. This results in improper development of the infant's lungs. In adults, a hiatal hernia will cause indigestion and chest pain. In infants, a diaphragmatic hernia will cause difficulty breathing, blue skin, and a rapid heartbeat.
