What is gastroesophageal reflux disease? How does it happen?
Gastroesophageal Reflux Disease (GERD) means the disease with the symptom that comes from the abnormal flow back of acid or digestive juice in the upper esophagus, which can occur in the afternoon or at night. The symptom might occur from irritation, which might be esophagitis with wound or esophagitis without wound. If the acid flows back above the sphincter of the upper esophagus, it might cause atypical or extraesophageal GERD. For example: Lung or throat symptom and Laryngophryngeal Reflux (LPR).
Normally, the body will have the mechanism to prevent the flow back of acid in the stomach and above in the upper gastrointestinal tract system. For example: The constriction of esophagus from top to bottom, and the function of sphincter of upper to lower esophagus. The membrane of esophagus has the mechanism to prevent the destruction from acid.
For the cause of GERD, it is believed that the sphincter of lower esophagus is abnormally loose, which causes the flow back of acid into the esophagus. Normally, if GERD flows back to the pharynx, it will stimulate the sphincter of upper esophagus to shrink in order to prevent the GERD from flowing back. It is believed that the preventive system of patient with atypical or extraesophageal GERD has malfunctioned so the GERD can flow back into the pharynx, larynx, and lungs.
