Hyperreactivity Basics
Airway hyperreactivity involves exaggerated airway narrowing in response to stimuli and contributes to asthma symptoms and airflow limitation.
Trigger Response
Triggers include allergens exercise cold air and irritants which provoke bronchoconstriction.
Inflammatory Role
Inflammation increases airway sensitivity and worsens hyperreactivity.
Diagnostic Evaluation
Evaluation includes spirometry bronchoprovocation testing and clinical assessment.
Treatment Approaches
Treatment includes bronchodilators anti inflammatory therapy and trigger avoidance.
