A paraesophageal hernia is also known as a hiatal hernia, where a portion of the stomach slides through the diaphragm and into the chest. This may cause symptoms of pain, heartburn, reflux, and difficulty swallowing food. Sometimes it causes food or even liquids to become stuck as they go down the esophagus.
The diaphragm is a sheet of muscle that separates your belly (abdomen) from your chest. The hernia bulges through the diaphragm at a place called the hiatus. This is the opening in the diaphragm that the esophagus passes through. The esophagus is the tube that connects the throat to the stomach. There are three main types of hiatal hernia: sliding, paraesophageal, and mixed. Most people who have a hiatal hernia have a sliding hiatal hernia .
