Asthma

Asthma is a chronic lung disease that inflames and narrows the airways. Symptoms include wheezing, coughing, chest tightness, and shortness of breath. Asthma can be controlled with medication and by avoiding triggers such as smoke, pollen, and dust.

There are many asthma treatments available, depending on the severity of the asthma and the person's age. Mild asthma may only require a short-acting bronchodilator such as albuterol, while more severe asthma may require daily use of a controller medication such as an inhaled corticosteroid. Some people with severe asthma also require regular use of a rescue medication such as an inhaled beta2-agonist.
