SUMMARY

1. Non-specific airway hyperresponsiveness leading to airway oedema and bronchoconstriction.

2. Persistent airway inflammation leads to remodelling of the airways with fibrosis & muscular hypertrophy resulting in a continuous non-responsive airflow obstruction.

3. Early in an asthmatic attack, bronchospasm is the major factor. Later, increased airway inflammation, edema, & secretions with mucous plugging may dominate.
