The main analysis of rhinitis causing tonsillitis is as follows: 1. Rhinitis, for example, acute rhinitis is mostly induced and caused by viral infection. The virus can enter the throat through the nasal backflow of nasal mucus and involve the surface of the tonsils, and the virus in the secretions can likewise invade the tonsils and cause the patient to develop tonsillitis. . 3. Rhinitis causes the nose to become unventilated, thus inducing changes related to open-mouth breathing and snoring when the patient sleeps. As the viruses and bacteria in the air are not sterilized and sterilized by the nasal cavity, they enter directly from the mouth and pharyngeal cavity, which can easily induce local viral and bacterial infections in the tonsils over time, thus inducing tonsillitis. So rhinitis can induce tonsillitis, in this case, we should actively and quickly treat rhinitis to avoid further aggravation of the disease.
