Which of the following is a sign of an asthma attack?

Difficulty breathing and wheezing are key signs of an asthma attack. During an asthma attack, the airways become inflamed and narrowed, which significantly hampers airflow. This constriction leads to the typical symptoms of shortness of breath, difficulty in exhaling, and tightness in the chest. Wheezing, which is a high-pitched sound produced when breathing, results from the restricted airflow and is often a clear indication that someone is experiencing an asthma attack.

Other symptoms like chest pain and nausea, excessive sweating, or dizziness can occur due to various medical conditions but are not characteristic of an asthma attack. Therefore, recognizing difficulty breathing and wheezing as hallmarks of this respiratory condition is crucial for timely intervention and management.
