Allergic rhinitis sneezing is mainly caused by inhalation of allergens in the nasal cavity, resulting in rapid allergic reactions in the nasal mucosa. Sneezing is one of the most prominent clinical manifestations of allergic rhinitis, which is mainly caused by the patient’s nasal mucosa coming into contact with airborne allergens such as pollen, dust mites and dust, which leads to rapid allergic reaction in the nasal cavity, causing the patient’s nasal mucosal exudate to increase and triggering the symptom of sneezing. However, long-term sneezing may aggravate the patient’s rhinitis symptoms, so the patient must keep away from allergens in time, or follow the doctor’s instructions to use mometasone furoate nasal spray, fluticasone propionate nasal spray and other medications to alleviate the treatment. To summarize, if allergic rhinitis patients have severe or persistent sneezing symptoms, they should go to the hospital in time, to clarify the cause of the disease and target treatment.
