BRONCHOCONSTRICTION

The airways of patients with asthma are hyperresponsive to a variety of stimuli, that is, they respond more than airways in healthy subjects. These stimuli include allergens, specific foods (e.g. peanuts), chemicals (e.g. histamine, metacholine), and physical factors (e.g. cold air, exercise, dust). The airway response to such stimuli are measured under controlled laboratory conditions as diagnostic tests.
