Asthma is a common chronic disorder of the airways that involves a complex interaction of airflow obstruction, bronchial hyperresponsiveness and an underlying inflammation. This interaction can be highly variable among patients and within patients over time.

Asthma involves many patho - physiologic factors, including bronchiolar inflammation with airway constriction and resist-ance that manifests as epi-sodes of coughing, shortness of breath, and wheezing. Asthma can affect the tra - chea, bronchi, and bronchi-oles. Inflammation can exist even though obvious signs and symptoms of asthma may not al ...
3 Μαΐ 2024 · Pathophysiology. Asthma is a syndrome characterized by diverse underlying mechanisms and involves intricate interactions among inflammatory and resident airway cells. These mechanisms lead to airway inflammation, intermittent airflow obstruction, and bronchial hyperresponsiveness (see Image. Pathophysiology of Asthma). Airway Inflammation

basic features of asthma include episodic airways inflammation, airways hyperresponsiveness, and mucous hypersecretion. Although we understand the basic clinical features of asthma, the links between symptoms, physical signs, and underlying pathophysi-ological mechanisms are still being delineated. Asthma
The Pathophysiology of Asthma ]ames C. Hogg, M.D. • For the purpose of this discussion, the pathophysiologic features of asthma will be di vided into muscle spasm, airways inflammation with edema, and mucus hypersecretion. While all three are relatively constant features of asthma, their propor
