Asthma occurs when the main air passages of your lungs, the bronchial tubes, become inflamed. The muscles of the bronchial walls tighten, and cells in the lungs produce extra mucus further narrowing your airways. This can cause minor wheezing to severe difficulty in breathing. In some cases, your breathing may be so labored that an asthma attack becomes life-threatening.
Asthma is a chronic but treatable condition. You can manage your condition much like someone manages diabetes or heart disease. You and your doctor can work together to control asthma, reduce the severity and frequency of attacks and help maintain a normal, active life.
Asthma signs and symptoms can range from mild to severe. You may have only occasional asthma episodes with mild, short-lived symptoms such as wheezing. In between episodes you may feel normal and have no difficulty breathing. Some people with asthma have chronic coughing and wheezing punctuated by severe asthma attacks.
Most asthma attacks are preceded by warning signs. Recognizing these warning signs and treating symptoms early can help prevent attacks or keep them from becoming worse.
