Asthma is an inflammatory condition of the bronchi, which are the airways of our lungs. When a person has an asthma attack, the muscles around their airways tighten and the lining of the air passages swells. This is often accompanied by increased mucus production which clogs the airways. These three things combined reduce the amount of air that can pass through the bronchi, causing shortness of breath and other associated symptoms.
