Asthma is a chronic respiratory condition that causes difficulty in breathing. Asthma attacks occur when the airways become inflamed and narrow, making it difficult for air to flow in and out of the lungs. During an asthma attack, symptoms such as shortness of breath, wheezing, coughing, and chest tightness may worsen or appear suddenly. Asthma attacks can be triggered by various factors including allergies, exercise, stress, cold air, or viral infections. Treatment for asthma typically involves the use of medications to manage symptoms and prevent future attacks.
