Human digestive system the esophagus at its upper end and to the duodenum at its lower end. Gastric acid (informally "gastric juice"), produced in the stomach plays a vital role in the digestive process, and mainly contains hydrochloric acid and sodium chloride. A peptide hormone, gastrin, produced by G cells in the gastric glands, stimulates the production of gastric juice which activates the digestive enzymes. Pepsinogen is a precursor enzyme (zymogen) produced by the gastric chief cells, and gastric acid activates this to the enzyme pepsin which begins the digestion of proteins. As these two chemicals would damage the stomach wall, mucus is
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),
