Allergic rhinitis is medically known as allergic rhinitis, or allergic rhinitis for short, and is commonly referred to as allergic rhinitis. As the name suggests, it refers to an allergic reaction in the nasal mucosa, i.e. an abnormal reaction manifested by the nasal mucosa due to increased sensitivity of the body to certain allergens, i.e. substances that cause allergies, and is a common manifestation of respiratory allergic reactions and the most common type of allergic disease. It is divided into perennial allergic rhinitis (no significant seasonal differences in onset) and seasonal allergic rhinitis (only seasonal attacks every year). The incidence of allergic rhinitis has been increasing in recent years due to changes in people’s diet and environmental pollution, which has caused people who were not allergic to become allergic. According to a set of statistics, children with allergic rhinitis account for about 40% of the total number of children with rhinitis. More than 30% of children with allergic rhinitis will eventually develop asthma. Therefore, allergic rhinitis patients should not take the disease lightly.
