I believe that many patients have experienced being diagnosed with “chronic pharyngitis” or “chronic laryngitis” after visiting otorhinolaryngology for symptoms such as dryness, pain, hoarseness, foreign body sensation, burning sensation and chronic cough. Patients often go through a variety of tests to describe the mucous membrane of the throat is congested and even swollen, lymphatic follicular hyperplasia and other manifestations, for which they have taken a large number of so-called pharyngitis drugs, anti-inflammatory drugs, etc., and even underwent laser and so-called plasma surgery for this purpose, but did not obtain substantial results, and some people even have different degrees of psychological disorders. You may not believe it, but in fact about 80% of these patients are suffering from “reflux laryngitis”. Some people may ask how can I be diagnosed with reflux laryngitis when I have no obvious digestive symptoms such as burning pain in the throat, acid reflux, heartburn, stomach pain, or bloating? In fact, this is a cause of misdiagnosis, because some patients with reflux disease do have no obvious symptoms of reflux, or there are no symptoms of reflux during the day but only reflux during sleep at night and is called invisible reflux, and some patients do not even observe reflux when they undergo gastroscopy. If a doctor has limited knowledge in this area or does not take a careful history and pursue traces of reflux about gastric disease, he or she will often be told that it is chronic pharyngitis, and long-term misdiagnosis and mistreatment is inevitable. As for the patients, they should also give up the headache and foot-dragging way of thinking and cooperate with their doctors in the screening and treatment of reflux. So how does reflux disease occur? We know that under normal circumstances, when food enters the entrance of the stomach through the esophagus after the cardia, the cardia sphincter closes, the stomach food and gastric acid and other gastric contents can not reflux to the esophagus or higher parts and when various reasons cause the lower esophagus and cardia sphincter relaxation, the role of this one-way live valve is weakened or disappeared resulting in gastric contents reflux to the esophagus and even the pharynx, stimulating If there is a combination of gastric dysfunction or lying down after meals, the chance of acid reflux into the throat increases significantly and the symptoms become more obvious. Therefore, for those patients with chronic pharyngitis that is untreated and repeatedly prolonged, in addition to consulting with respiratory medicine and cardiovascular medicine to exclude allergic hyperreactive diseases of the airway such as asthma and myocardial ischemic diseases such as coronary heart disease, both doctors and patients should pay attention to the possibility of reflux pharyngitis, and should consult with the gastroenterology department for gastroscopy, etc. to clarify the diagnosis and treat accordingly. At present, the main therapeutic drug is the use of proton pump inhibitors such as esomeprazole or omeprazole or even gastric motility drugs to inhibit gastric acid, promote gastric emptying, and control reflux. 6-8 weeks of continuous medication is recommended, and some suspected cases even without obvious reflux symptoms can be treated on a trial basis. In addition, it is also very important to pay attention to the correction of poor lifestyle, such as quit smoking and alcohol, do not consume all kinds of stimulating food and drinks, eat less dinner, do not eat 2 hours before bedtime, elevate the head of the bed or high pillow and shoulder pad, etc. It is believed that after active treatment and psychological guidance will obtain satisfactory results.
