Asthma attack, also called asthma flare or acute bronchospasm, is the sudden narrowing and tightening of the lower airways (bronchi) in the lungs, that can make it hard to breathe. The narrowing is caused by inflammation and tightening of the smooth muscle that wraps around the lower airways in the lungs.
Asthma attacks may cause coughing, high-pitched whistling sounds when you breathe, most often when you breathe out (wheezing), trouble breathing (shortness of breath), and chest pain. The airways may produce extra mucus caused by the inflammation and irritation. During an asthma attack, it can be difficult to breathe. It is important to get treatment right away. Asthma attacks can range from minor to life-threatening.
