Asthma triggers


A wide range of factors can trigger asthma, and triggers differ between individuals.

Most of the evidence that certain exposures and physiological factors can trigger asthma comes from cross-sectional population studies and cohort studies. Because there is insufficient evidence to confirm without doubt whether some factors can or cannot act as triggers for an individual, triggers and avoidance strategies must be discussed with each patient.
