Pharyngeal discomfort, foreign body sensation in the pharynx, and phlegm that cannot be easily coughed up are common complaints of patients in outpatient clinics and are often diagnosed as pharyngitis, which is also the most common diagnosis in ENT departments during physical examinations, so although the diagnosis of pharyngitis is good, it is not easy to determine the cause. There are few pharyngitis caused by bacteria, viruses and other microorganisms, and acute is common, while chronic pharyngitis, with many causes, requires careful screening, both the impact of adjacent systems such as the digestive system (gastroesophageal reflux), as well as systemic systems such as immune system diseases (such as dry syndrome, etc.), gastroesophageal reflux resulting in reflux pharyngitis is a more common cause, due to the relaxation of the sphincter of the esophagus leading to the reflux of gastric juices to the Nearly half of patients do not have acid reflux or hiccups (i.e., occult reflux), and severe cases can cause a feeling of choking and paroxysmal dyspnea. There is a scale below to determine if your pharyngitis is caused by reflux, try to give yourself a score, if the scores add up to 13 or more, it is likely to be caused by reflux and you need to go to the hospital for treatment.
