Asthma is a chronic lung disease characterized by airway obstruction, inflammation, and hyper-responsiveness [1,2]. A broad range of factors has been identified that can make asthma worse. These factors are often referred to as "asthma triggers." Trigger exposure may occur on a chronic or episodic basis. Identifying and avoiding asthma "triggers" is essential to preventing asthma flare-ups.

A description of factors that may contribute to asthma severity and suggestions for mitigation of these factors will be reviewed here. A general approach to asthma management is provided separately. (See "An overview of asthma management".)


Asthma "triggers" are often thought of as airborne agents that can bring on an attack, but a variety of other exposures can cause or exacerbate symptoms, including the following categories of stimuli [1,2]:

Respiratory infections (viruses, bacteria)

Allergen exposure (inhalant, food, and occupational)
