Asthma occurs when the main air passages of your lungs, the bronchial tubes, become inflamed. This airway narrowing causes symptoms such as wheezing , shortness of breath , chest tightness, and coughing , which respond to bronchodilators. The inflammation (IN-fla-MAY-shun) makes the airways very sensitive, and they tend to react strongly to things that you are allergic to or find irritating. These asthma triggers vary and may include exercise, cold air, allergens (such as dust, ragweed, mold, or cat dander), infections, and emotional reactions. Some people suffer asthma symptoms continuously; others experience them only if exposed to triggers. Regardless of the cause, severe asthma is a serious health concern that can lead to respiratory failure and death.
