What Is Allergic Rhinitis?

Allergic rhinitis is a chronic allergic inflammatory condition of the nasal mucosa triggered by exposure to external allergens, and it is one of the most common respiratory allergic disorders. Characterized primarily by nasal discomfort, this disease tends to recur frequently and is difficult to cure completely. Persistent nasal congestion and rhinorrhea that fail to improve require timely medical consultation and standardized treatment.

The pathogenesis of allergic rhinitis stems from an abnormal immune response: the body mistakenly identifies harmless substances—such as pollen and house-dust mites—as threats, thereby continuously triggering nasal mucosal congestion and edema, which leads to classic symptoms including nasal obstruction, sneezing, and watery rhinorrhea. The current standard clinical management involves allergen avoidance combined with pharmacotherapy; antiallergic medications help reduce mucosal inflammation, alleviate symptoms, and stabilize nasal function.

In patients with refractory disease, drug therapy alone may yield limited efficacy; in such cases, allergen-specific immunotherapy (desensitization therapy) can be considered to modulate the immune system and gradually decrease the body’s sensitivity to specific allergens. Inadequate daily precautions often lead to frequent relapses, and prolonged uncontrolled disease may predispose individuals to complications such as sinusitis and nasal polyps, thereby adversely affecting both respiratory health and quality of daily life.

For daily management, maintain a clean, well-ventilated living environment; regularly clean household surfaces to remove dust mites and pollen; minimize outdoor activities during seasonal allergen peaks to reduce exposure; and engage in regular, moderate physical exercise to strengthen overall constitution and enhance respiratory defense capacity.
