Rhinitis can cause bronchitis. Rhinitis that can cause bronchitis in clinical practice is mostly seen in the following two conditions: first, acute rhinitis, which is commonly known as a cold or flu, and is mostly an inflammation of the upper respiratory tract caused by a viral infection. In addition to acute rhinitis, there can be manifestations of bronchitis, such as coughing, coughing, and suffocating wheezing, especially in children and adolescents. The second is allergic rhinitis, which is mainly an airway allergy, that is, the “same airway, same disease” rationale. In addition to the manifestations of allergic rhinitis, such as paroxysmal sneezing, nasal itching, and clear watery snot, there are also manifestations of asthmatic bronchitis, such as wheezing attacks, chronic cough or atypical variant asthma, repeated coughing, throat clearing, and other actions.
