Which symptom is typically associated with asthma attacks?

Wheezing is a hallmark symptom of asthma attacks and occurs due to the narrowing of airways. This narrowing results from bronchial constriction and inflammation, leading to difficulty in breathing, particularly during expiration. The sound of wheezing is caused by turbulent airflow through constricted air passages, which can often be heard without a stethoscope, making it a key indicator for healthcare practitioners diagnosing asthma.

Other symptoms like frequent coughing and an increased respiratory rate can also be present in asthmatic patients, but they are not as specific or definitive as wheezing. Severe chest pain is generally not typical in asthma and may indicate other conditions, such as cardiovascular issues. Therefore, while the other symptoms may be observed in asthmatic patients, wheezing distinctly characterizes an asthma attack.
