A diaphragmatic hernia is a condition where an opening in the diaphragm, the muscle that separates the chest from the abdomen, allows abdominal organs to move into the chest cavity. This can lead to breathing difficulties and other complications, as the lungs may not have enough space to expand properly. Diaphragmatic hernias can be congenital, meaning they are present at birth, or acquired due to injury or surgery. Symptoms may include shortness of breath, rapid breathing, and gastrointestinal issues. Diagnosis typically involves imaging tests like X-rays or CT scans, and treatment often requires surgical intervention to repair the hernia.
