Allergic rhinitis is a common, chronic, inflammatory disorder of the nasal lining triggered by immunoglobulin E (IgE)-mediated reactions to environmental allergens such as pollen, dust, animal dander, and moulds. It is characterized by nasal congestion, watery discharge from nose, sneezing, nasal itching, and watery eyes, which may affect the quality of life. Though it is not life-threatening, Allergic rhinitis is a major global health concern due to its increasing prevalence for the past few decades due to environmental changes, lifestyle factors and genetic predisposition. Approximately 10-30% of the population suffers from Allergic rhinitis. Despite its high prevalence, leading to persistent symptoms and complications, the severity of allergic rhinitis can range from mild, intermittent symptoms to moderate-to-severe persistent disease. Classification systems such as the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines classified patients on symptom duration and impact on daily activities, sleep, quality of life. Understanding both the prevalence and the severity of allergic rhinitis within specific populations is essential for guiding public health, improving clinical management and reducing disease affection and to improve the preventive measures. This thesis aims to access whether the phenotypes of ABO have predisposition to cause allergic rhinitis and to compare the prevalence and severity of allergic rhinitis among the individuals.
