Chronic pharyngitis may induce pneumonia, chronic pharyngitis is mainly manifested as chronic inflammation of the pharyngeal mucosa and submucosal tissues, long-term chronic pharyngitis tends to make the immune function of the patient’s pharynx under the mucosa become poor. Once the immune function becomes poor resulting in external viruses and bacteria, it is difficult to be inactivated by the immune cells in the back of the pharynx, the root of the tongue and other parts of the body, resulting in viruses and bacteria easily entering the trachea and lungs, thus indirectly triggering pneumonia in patients. Therefore, chronic pharyngitis itself may not lead to pneumonia, but chronic pharyngitis causes the first immune system of the patient’s throat to deteriorate, resulting in external viruses and bacteria without a barrier effect, which can easily enter the lungs and trachea, triggering the patient to develop lung and tracheal infections, resulting in pneumonia and other related diseases. So clinically for chronic pharyngitis should also be actively treated to improve the immunity of patients, including the immune status of the mucosa of the throat.
