Asthma is a chronic respiratory condition. It occurs when the airways in our lungs become inflamed and narrow, making it difficult to breathe. This inflammation is usually triggered by certain substances or situations, such as allergens (like pollen or pet dander), exercise, or respiratory infections.

When a person with asthma encounters one of these triggers, their airways become sensitive and react by constricting (getting narrower) and producing extra mucus. This restricts the airflow and can lead to symptoms like coughing, wheezing, shortness of breath, and chest tightness. These symptoms can vary in severity from person to person and can be managed with medications like inhalers.

It’s important for individuals with asthma to identify their triggers and develop an asthma action plan with their healthcare provider. This plan includes steps to prevent and manage asthma attacks, as well as emergency measures if symptoms become severe.
