Environmental allergies are IgE-mediated reactions to airborne triggers — tree, grass, and weed pollens, dust mites, animal dander, mold spores, and cockroach proteins. They cause sneezing, congestion, itchy or watery eyes, post-nasal drip, and worsen asthma. Symptoms often follow seasonal patterns or specific exposures. Management starts with allergen identification and avoidance, intranasal steroids, second-generation oral antihistamines, and saline rinses. Allergen immunotherapy — subcutaneous shots or sublingual tablets for selected allergens — is the only treatment that modifies the underlying disease.
