Long-term dry throat itching and swelling, coughing hoarseness, brushing teeth in the morning want to dry vomit …… chronic laryngitis is many modern people “speechless pain”. The most troubling thing for patients is that some people can get relief by using some cooling Chinese medicine to dispel fire; however, some people use the medicine, not only the effect is very poor, and even counterproductive, and this is why? In clinical practice, the latter group of patients often painfully tell doctors that they not only have redness and swelling in the throat, but also have long-term pain and foreign body sensation in this area. In fact, these patients have symptoms caused by reflux gastric juice erosion and irritation of the pharynx, and GERD is the real “culprit” behind the scenes. Therefore, if, after excluding pharyngitis due to nasopharyngeal disease, there is acidity, belching, or a burning sensation behind the sternum, and the more severe these symptoms are, the more likely it is that reflux pharyngitis is present. Patients with persistent chronic laryngitis that does not heal over a long period of time should be vigilant. There are three possible reasons for this: first, acid reflux due to burping after eating too much; second, relaxation of the upper esophageal sphincter; and third, the flow of acid-like substances into the pharynx at the proximal end of the esophagus when lying down at night due to the lowering of the head. Therefore, these patients should, firstly, avoid overeating or eating before going to bed, and not take drugs that affect the power function of the esophagus; secondly, when sleeping, the pillow should be properly padded so that the head is elevated, which can help reduce the occurrence of reflux pharyngitis; again, if it is clear that there is “acid” in the throat, in addition to the local application of anti-inflammatory drugs, throat Finally, avoid the long-term stimulation of the stomach by tobacco, alcohol, strong tea and coffee to avoid stomach discomfort and increased acidity, stimulating the mucous membrane of the throat, causing the persistence of inflammation in the throat and even aggravation.
