Asthma is a lung disease that presents with acute asthma exacerbations and reversible airflow obstruction. It develops most often in childhood and is triggered later on by allergens such as dust, pollen, and certain animals. Still, there are other triggers, such as cold air, exercise, medications, and viral infections. At Halton Pediatrics, our pediatric asthma specialist offers parents and their children with asthma; diagnosis, management, education, and follow-up access to help manage their asthma.
