Asthma attacks or “flare-ups” occur when the airways become inflamed and narrowed, making it hard to breathe. They often take place as a reaction of the lungs to an external substance (“trigger”) that a patient comes into contact with. This section explains how exacerbations occur and what to do when they happen.
