Asthma is a chronic disease involving the airways (tubes) that carry air in and out of the lungs. These airways are inflamed in people with asthma. The inflammation makes the airways very sensitive, and the tubes often react to allergens or irritations. There is no cure for asthma. But with the proper diagnosis, medication and an asthma management plan, symptoms can be controlled. Asthma symptoms may include wheezing, coughing, chest tightness and trouble breathing-especially early in the morning or at night. In a severe asthma attack, the airways close so much that other vital organs in the body do not get enough oxygen. Asthma is treated with two kinds of medicines. Long-term controller medications are typically taken daily to prevent symptoms. Quick-relief medicines stop asthma symptoms when they occur.
