Bochdaleck Hernia is a rare disorder characterized by an opening in the diaphragm (layer underneath the lungs) at birth, causing some abdominal organs to grow into the area normally occupied by the lungs. Depending on how the abdominal organs grow, the symptoms can vary, but most individuals with the disorder have problems related to the lungs. Common symptoms individuals may face include respiratory distress, difficulty breathing, and periods of rapid breathing. Doctors often diagnose this disorder very early in life, since the symptoms are very apparent. Treatment is developed on a case-by-case basis depending on the severity of the abnormal growth. Lung specialists may provide patients with breathing exercises to help strengthen the lungs, but may discourage them from participating in strenuous activities. In severe cases, doctors may suggest individuals undergo surgery to fix the opening in the diaphragm and reposition the abdominal organs.
