Asthma may be a common long-term disease of the airways of the lungs. it's characterized by variable and recurring symptoms, reversible airflow obstruction, and simply triggered bronchospasms. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These may occur a couple of times each day or a couple of times per week. counting on the person, asthma symptoms may go to pot in the dark or with exercise.
Asthma is assumed to be caused by a mixture of genetic and environmental factors. Environmental factors include exposure to pollution and allergens. Other potential triggers include medications like aspirin and beta blockers. Diagnosis is typically supported the pattern of symptoms, response to therapy over time, and spirometry lung function testing. Asthma is assessed consistent with the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow . it's going to even be classified as atopic or non-atopic, where atopy refers to a predisposition toward developing a kind 1 hypersensitivity.
