Wheezing is a common clinical sign of asthma observed during a physical examination. It occurs due to the narrowing of the airways, which causes a high-pitched whistling sound during expiration. This sound is a direct result of the airflow being obstructed by inflammation, bronchospasm, and mucus production—key features of asthma. Wheezing can often be heard by a clinician using a stethoscope during a respiratory examination and is an important indicator of asthma exacerbations.

While symptoms such as chest tightness, persistent cough, and shortness of breath are also associated with asthma and significant in understanding the patient’s condition, wheezing is more specifically tied to the mechanical process of airflow obstruction in the bronchial tubes. Therefore, it is considered a hallmark physical sign during an examination of a patient with asthma.
