Allergic rhinitis is a type of hypersensitivity disease, with clinical symptoms primarily presented in the nasal cavity. Its main manifestations are nasal congestion, nasal itching, abundant clear nasal discharge, continuous paroxysmal sneezing, and reduced sense of smell. If the allergies in allergic rhinitis are not effectively controlled, the allergic symptoms may progress downward, potentially leading to allergic pharyngitis, characterized by an itchy throat, dry cough, and hoarse voice. If it continues to develop further, it can lead to allergic asthma. This is clinically referred to as "one airway, one disease." Therefore, it is crucial to actively intervene and provide appropriate treatment for allergic rhinitis.
