asthma exacerbations

Asthma exacerbations are episodes where asthma symptoms suddenly worsen, making it difficult to breathe, cough, or wheeze. They occur when the airways become inflamed and swollen, often triggered by infections, allergens, pollution, or physical activity. During an exacerbation, muscles around the airways tighten, and extra mucus is produced, narrowing the airflow. This can be serious if not treated promptly, leading to shortness of breath and fatigue. Managing asthma involves controlling triggers and using medications like inhalers to prevent or treat these episodes, reducing the risk of severe breathing problems.
