Allergic rhinitis is recommended to consult an otorhinolaryngology department. Currently, allergic rhinitis is mainly due to an imbalance in one's own immune system, which, upon contact with external allergens, triggers an allergic reaction in the body. It is a relatively common nasal disease, hence the recommendation to visit an otorhinolaryngology department. Regarding examinations, allergen testing and nasal endoscopy are required. The main purpose is to identify the relevant allergens and to determine the presence of any neoplasms in the nasal and nasopharyngeal areas, such as nasal polyps. In terms of treatment, it primarily involves medication. Currently, the treatment mainly considers the use of oral medications and nasal spray medications for allergy treatment. Additionally, the use of saline to rinse the nasal cavity can be considered, along with regular follow-ups. However, overall, most patients with allergic rhinitis focus on controlling the condition, as it is difficult to completely cure.
