Asthma is a chronic respiratory condition in which the airways can become inflamed and narrowed, causing symptoms such as wheezing, coughing, chest tightness and shortness of breath. Symptoms may vary over time and can be triggered or worsened by allergens, respiratory infections, smoke, air pollution, exercise, weather changes and other individual triggers.
Asthma can affect children and adults. The pattern and severity of symptoms can differ considerably between individuals. A proper medical assessment helps distinguish asthma from other conditions that can cause similar breathing symptoms.
