monitoring
2

Respiratory therapy and management

Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.

3

Bronchodilator therapy

Short-acting beta-agonist bronchodilators to relieve acute symptoms and long-acting agents for maintenance therapy in patients with confirmed airway hyperreactivity.

medication

Additional treatment options

Environmental trigger avoidance

Identification and elimination of environmental triggers such as tobacco smoke, air pollutants, allergens, and occupational exposures that may exacerbate bronchial hyperreactivity.

lifestyle

Breathing exercises and pulmonary rehabilitation

Structured breathing retraining and pulmonary rehabilitation program to improve respiratory efficiency, reduce hyperventilation, and enhance overall lung function.
