Allergic rhinitis, also known as allergic rhinitis, is one of the most common human diseases, with a prevalence of 10% to 40% in the general population, of which 30% of allergic rhinitis patients are accompanied by bronchial asthma. The onset of allergic rhinitis is closely related to genetics and the environment. Due to the aggravation of environmental pollution, the number of various antigens and allergens is increasing, and now in spring, pollen allergens are increasing in large quantities, which is the high incidence season of allergic rhinitis. Allergic rhinitis is divided into perennial allergic rhinitis and seasonal allergic rhinitis. Seasonal allergic rhinitis, also known as “hay fever”, has symptoms such as itchy nose, eyes and ears, paroxysmal sneezing, large amounts of clear water nasal discharge, nasal congestion, etc. It can be accompanied or followed by bronchial asthma and sinusitis, causing loss of smell and insomnia, which can seriously affect the patient’s This disease can occur at any age. This disease can occur at any age, especially in children and adolescents. Common allergens for allergic rhinitis include: plant pollen, airborne dust, indoor formaldehyde, outdoor sulfur dioxide, animal fur, dust mites, insects, mold spores, and food. Preventive measures for allergic rhinitis include: identifying the causative allergens, going to a regular hospital otorhinolaryngology department to detect in vivo or in vitro allergens, and taking targeted measures to avoid causative allergens: there is a lot of pollen in spring, so people suffering from this disease should try to contact less with various plant pollens, improve indoor ventilation to reduce indoor floating dust, reduce the formaldehyde content in indoor air, hot water to wash bedding and pillowcases, and try not to keep pets. Pillow cases, no pets or contact with pets as much as possible, and proper abstinence from food allergies. Allergic rhinitis can be treated with medication, immunotherapy, physical therapy, and surgery. Patients who cannot avoid the causative allergens or whose preventive measures are ineffective can be treated by the above methods. Drug therapy includes systemic medication and/or local nasal medication; firstly, local nasal medication is used, and systemic medication can be added for those who have poor results in local nasal medication; for those who have poor results in medication, immunotherapy or physical therapy can be used; immunotherapy uses desensitization therapy, but its course is long, requiring 1-2 years of treatment time; physical therapy can use laser, freezing, radiofrequency, microwave and other methods; for those who have poor results in medication, immunotherapy and physical therapy can be used. For those who are not effective in drug treatment, immunotherapy and physiotherapy and have very poor nasal ventilation, surgery can be used. Various treatment methods have their advantages and disadvantages, and the best treatment plan can be determined only after the necessary examination in the otorhinolaryngology department of a regular hospital.
