What Causes a Throat Hernia?

A hernia protrudes into or next to the esophagus through the hiatus — an opening that connects the esophagus to the stomach — and potential causes include injury, extreme coughing and pregnancy. There are two primary types of hiatal hernia as listed by the Cleveland Clinic. The more common sliding hiatal hernia is when the connection between the stomach and the esophagus pushes up into the chest, and the more severe paraesophageal hernia is where the stomach gets pushed up through the diaphragm and next to the esophagus.
