There is no difference between allergic rhinitis and allergic rhinitis, they are two different terms that refer to the same disease. Allergic rhinitis is a colloquial and popular term used in everyday life, while allergic rhinitis is a medical term. Allergic rhinitis is an inflammatory disease of the mucous membrane in the nasal cavity caused by exposure of atopic individuals to allergens. The main symptoms are repeated sneezing, itchy nose, nasal congestion, and runny nose, which may be accompanied by conjunctival congestion and tearing of the eyes. In severe cases, allergic pharyngitis and allergic asthma may develop. Allergic rhinitis can be recurrent, with a long disease cycle and a long treatment period. The main treatment is anti-allergy therapy under the guidance of a specialist, including oral anti-allergy drugs such as loratadine and cetirizine, and nasal sprays such as budesonide spray and fluticasone spray. Specific immunotherapy, also known as desensitization, can also be taken depending on the allergen. In addition, exposure to seasonal allergens and common year-round allergens should be avoided. For example, pollen and willow flakes are seasonal allergens, while house dust mites, animal fur, and fungi are year-round allergens. When allergic rhinitis occurs, it is necessary to actively seek medical treatment and medication should be rationally applied under the guidance of a physician.
