Asthma is a common respiratory illness characterized by airway hyperresponsiveness and inflammation. It affects over 300 million people globally (1), including 22 million adults in the United States alone. Although asthma mortality in the United States has declined, the morbidity and costs remain substantial. In certain groups of Americans, such as persons of lower socioeconomic status and minority ethnicity, asthma morbidity and mortality are disproportionately high. Such trends are surprising, given the improvement in air quality in the United States and the availability of effective therapies.
Symptoms that should prompt clinicians to consider asthma are episodic wheezing, dyspnea, cough, difficulty taking a deep breath, and chest tightness (2, 3). A careful history to elicit the nature and timing of symptoms is paramount in diagnosing asthma. Characteristically, asthma symptoms are intermittent and may remit spontaneously or with use of short-acting bronchodilators. Symptoms often vary seasonally or are associated with specific triggers, such as cold, exercise, animal dander, pollen, occupational exposures, certain foods, and aspirin or nonsteroidal anti-inflammatory drugs. Clinicians should also consider asthma in patients with chronic cough, especially if it is nocturnal, seasonal, or related to the workplace or a specific activity.
