Introduction to asthma, a lung condition common in kids and teens that causes breathing difficulties. It can be hereditary and ranges from mild to severe.

During an asthma attack, the smooth muscles around the bronchi and bronchioles tighten, and the mucosal lining swells, producing excess mucus. This narrows the airways and makes it difficult to breathe, specifically making it hard to exhale.

Prevention involves identifying and avoiding triggers like dust, smoke, or cold air. When exposure occurs, inhalers are used to deliver medication directly into the lungs.

The exact cause of asthma is unknown, though it is likely linked to a combination of genetic and environmental factors. Key facts include gender disparities in prevalence and the significant impact asthma has on school attendance.
