Allergic rhinitis is a common condition that occurs when the immune system overreacts to allergens in the air. This reaction causes inflammation and swelling in the nasal passages. People with allergic rhinitis often experience symptoms such as sneezing, runny or stuffy nose, itchy eyes, and throat irritation. Common triggers for allergic rhinitis include pollen, dust mites, pet dander, and mold. The condition can be seasonal, occurring mainly during certain times of the year, or perennial, affecting individuals year-round. Treatment options typically include avoiding known allergens, using medications like antihistamines and nasal corticosteroids, and sometimes immunotherapy to reduce sensitivity to allergens. Allergic rhinitis can significantly impact quality of life by disrupting sleep, reducing productivity, and causing general discomfort.
