Asthma is thought to be caused by a combination of genetic and environmental factors. Its diagnosis is usually based on the pattern of symptoms, response to therapy over time and spirometry.

It is clinically classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate.

Treatment of acute symptoms is usually with a short-acting broncodilator and oral corticosteroids.

In very severe cases, intravenous corticosteroids, magnesium sulfate, and hospitalization may be required.

Symptoms can be prevented by avoiding triggers, such as allergens and irritants, and by the use of inhaled corticosteroids.
