asthma attack

An asthma attack occurs when the airways in the lungs become inflamed and swollen, leading to narrowing that makes breathing difficult. During an attack, muscles around the airways tighten, and mucus production increases, further blocking airflow. Symptoms include shortness of breath, wheezing, coughing, and a feeling of tightness in the chest. Causes can include allergens, respiratory infections, exercise, or irritants. Asthma attacks vary in severity and require prompt treatment, often with inhalers that relax airway muscles and reduce inflammation. Effective management and avoidance of triggers help control asthma and prevent severe attacks.
