What primarily causes asthma?

Asthma is primarily caused by inflammation of the air passages. In this condition, the airways in the lungs become swollen and irritated, which can lead to difficulty breathing, wheezing, and coughing. The inflammation narrows the airways and increases sensitivity to various triggers, such as allergens, smoke, exercise, and respiratory infections.

Understanding the inflammatory aspect of asthma is critical because it affects the management and treatment of the condition. Treatments often include anti-inflammatory medications, such as corticosteroids, to reduce the inflammation and help open the airways. Recognizing that inflammation is at the heart of asthma can also help in identifying and avoiding triggers to prevent asthma attacks.
