Chronic pharyngitis has many causes, and common clinical causes include the following: First, it is caused by repeated inflammatory stimulation, commonly seen with acute pharyngitis and acute tonsillitis; second, it is due to long-term spicy diet stimulation, gastrointestinal dysfunction, and acid reflux stimulation. The acid liquid and vapors from reflux can irritate the mucosa of the throat, causing congestion, edema, and proliferation of lymphatic follicles in the mucosal lining. This leads to symptoms such as dry throat, sore throat, itchy throat, a foreign body sensation in the throat, a sensation of obstruction, and a burning sensation. Therefore, in treatment, patients first need to exercise, avoid colds, avoid inflammatory invasions, and at the same time, they need a light diet, to quit smoking and drinking, avoid spicy and irritating foods, regulate gastrointestinal function, and avoid acid reflux to gradually improve and prevent recurrent episodes.
