What does wheezing indicate during breathing?

Wheezing indicates difficulty breathing characterized by a high-pitched sound, typically heard during expiration. This sound occurs when air flows through narrowed or obstructed airways, often due to conditions such as asthma, allergic reactions, or bronchitis. The presence of wheezing suggests that there is an underlying issue affecting airflow, which may require medical attention.

Understanding wheezing is crucial, as it can help healthcare providers assess respiratory conditions and determine appropriate treatment options. In contrast, normal breathing patterns, a decrease in lung capacity, or clear airways indicate different respiratory statuses, which do not involve the high-pitched sound associated with wheezing.
