About this document
Asthma Pathophysiology and Risk Factors is a document available to read on EtoBox.
Asthma is caused by inflammation and narrowing of the airways. Risk factors include dust, emotional stress, anxiety, and heredity on the maternal side. During an asthma attack, substances like slow-reacting substance of anaphylaxis and histamine cause swelling of the airway muscles and increased mucus production, leading to difficulty breathing, coughing, and wheezing. Asthma can be treated with medications.
