What effect does asthma have on airflow?

Asthma has a significant impact on airflow, primarily by reducing it due to airway constriction, inflammation, and increased mucus production that are characteristic of the condition. During an asthma attack or when asthma is not well controlled, the airways can become narrow and obstructed, leading to difficulties in breathing and decreased airflow. This can manifest as wheezing, shortness of breath, and chest tightness, as the individual struggles to get adequate air in and out of the lungs.

Other effects of asthma include the increase in airway hyperresponsiveness, which means that the airways can react more strongly to various triggers, such as allergens, smoke, or cold air, exacerbating the reduction of airflow. Thus, individuals with asthma often experience variable airflow limitations, especially during acute episodes. This understanding highlights the overall impact asthma has on respiratory health, particularly in relation to airflow.
