Asthma Asthma is a disease in which inflammation of the airways causes airflow into and out of the lungs to be restricted. The muscles of the bronchial tree become tight and the lining of the air passages swells, reducing airflow and producing the characteristic wheezing sound. This is known as an asthma attack, which can occur as an allergic reaction to an allergen or other substance (acute asthma), or as a part of a complex disease cycle which may include reaction to stress or exercise (chronic asthma ). Asthma Definition Asthma is an inflammatory disorder of the airways, which causes attacks of wheezing , shortness of breath, chest tightness, and coughing.

When an asthma attack occurs, the muscles surrounding the airways become tight and the lining of the air passages swell. This reduces the amount of air that can pass by, and can lead to wheezing sounds. Most people with asthma have wheezing attacks separated by symptom-free periods. Some patients have long-term shortness of breath with episodes of increased shortness of breath. In others, a cough may be the main symptom. Asthma attacks can last minutes to days and can become dangerous if the airflow becomes severely restricted. In sensitive individuals, asthma symptoms can be triggered by breathing in allergy-causing substances (called allergens or triggers). Common asthma triggers include: Animals (pet hair or dander) Dust Changes in weather (most often cold weather) Chemicals in the air or in food Exercise Mold Pollen Respiratory infections, such as the common cold Strong emotions (stress) 4 | P a g e
Tobacco smoke Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) provoke asthma in some patients.
