Gastroesophageal reflux disease (GERD) This is commonly due to transient or permanent changes in the barrier between the esophagus and the stomach. This can be due to incompetence of the cardia, transient cardia relaxation, impaired expulsion of gastric reflux from the esophagus, or a hiatus hernia.
