Cause #9: Disorders of the Esophagus
Some disorders of the esophagus can cause bad breath. The lower esophageal sphincter located between the esophagus and the stomach may not function properly leading to gastroesophageal reflux disease (GERD).
This allows the excess acid to ascend and escape into the esophagus, leading to halitosis. Zenker’s diverticulum also causes retention of food in the esophagus which causes bad breath.
