As the esophagus does not have the same protection from acid as the stomach, any failure of this sphincter can lead to heartburn. The esophagus has a mucous membrane of epithelium which has a protective function as well as providing a smooth surface for the passage of food.

Chronic airway-digestive inflammatory disease cessation). Chronic airway-digestive inflammatory disease Sinus disease, allergies, and asthma have been shown to be intimately related through recent research. Moreover, gastroesophageal reflux disease (GERD), laryngopharyngeal reflux disease (LPRD) and/or snoring or sleep apnea are often present as well. “Chronic Airway-Digestive Inflammatory Disease” (CAID) is a phrase which has been coined by Dr. Jordan S. Josephson, M.D., F.A.C.S. and Dr. Jens Ponikeau, M.D. to describe this very complex set of problems which are caused by inflammation. This term was first described in a book entitled Sinus Relief Now .CAID directly affects the upper respiratory system (the nose and the sinuses),
