There are many possible causes of pharyngitis, among which smoking is one of the risk factors for the development of pharyngitis. Pharyngitis is an inflammatory disease that occurs in the mucous membrane of the pharynx as well as the submucosal tissues, and patients with pharyngitis often experience clinical symptoms such as pharyngeal pain, dry and burning sensation, and foreign body sensation. The causes of pharyngitis include pathogenic microbial infections, systemic diseases, and environmental factors. Smoking is one of the risk factors for pharyngitis, and the chemicals contained in tobacco can stimulate the inflammatory reaction of the mucosa of the pharyngeal cavity, and frequent smoking may aggravate the clinical symptoms of pharyngitis. Therefore, it is recommended that people with acute and chronic pharyngitis quit smoking to help relieve pharyngitis symptoms and avoid recurrence.
