The symptoms of pharyngeal reflux are mainly a foreign body sensation in the throat, and some patients may also experience hoarseness and difficulty in pronunciation. Most of the damage is caused by the direct stimulation of the pharyngeal mucosa by the refluxed stomach acid. If not treated in time, patients with severe development may develop laryngeal cancer, esophageal adenocarcinoma and secretory otitis media. After the development of pharyngeal reflux, acid suppression treatment by means of medication is required. It is important to avoid eating before bedtime, elevate the head of the bed, and reduce the intake of dinner and foods that are too sweet and acidic, which can significantly relieve the symptoms. In severe cases, or in cases where medication is not effective, surgical treatment is also available.
