Rhinitis (Allergic, Non-Allergic)

The nasal lining's irritation that results from rhinitis causes sneezing, congestion, and a runny nose. The cause determines the classification of rhinitis as either allergic or non-allergic.
Allergens, ranging from pollen to dust to pet dander to mould, cause allergic rhinitis. It sets off the immune system and releases histamines, causing watery eyes, sneezing, itching, and nasal congestion. Indoor allergens year-round cause perennial allergic rhinitis, while external allergens cause seasonal allergic rhinitis—hay fever.
Not immune-related, non-allergic rhinitis can arise from things like pollution, smoke, strong smells, drugs, or changing weather. Despite the absence of watery eyes or itching, the symptoms of non-allergic rhinitis are similar to those of allergic rhinitis. Irritating agents, not allergies, can trigger it.
Treatment relies on the kind of rhinitis one has. Antihistamines, nasal sprays, decongestants, and allergy avoidance help control allergic rhinitis. Severe cases may call for immunotherapy—allergy injections. Treatment for non-allergic rhinitis calls for avoiding irritants, using saline nasal sprays, and taking recommended drugs.
The appropriate treatment method for long-term alleviation and enhanced quality of life depends on a correct diagnosis made by a doctor
