What is it called when the diaphragm is out of normal position and has moved up further into the thoracic cavity?

When the diaphragm is displaced upward into the thoracic cavity, it is referred to as a "diaphragmatic hernia" or "hiatal hernia," depending on the specific context. This condition can lead to respiratory issues and is often associated with other medical conditions. In some cases, it might also be described as "eventration" if the diaphragm's movement is impaired without a hernia. Proper diagnosis and management are important for treatment.
