What is the cause of asthma?

Asthma is a chronic respiratory condition that is caused by inflammation and narrowing of the airways in the lungs. This inflammation can be triggered by a variety of factors, including allergens (such as pollen, dust mites, or pet dander), respiratory infections, air pollution, tobacco smoke, exercise, and certain medications. Genetics also play a role in the development of asthma, as individuals with a family history of the condition are more likely to develop it themselves.
