Upper airway wheezing Expiratory wheezing caused by the narrowing of a person’s trachea and, possibly, mainstem bronchi.

This tracheal narrowing and its accompanying wheezing can occur in a variety of circumstances or scenarios.

Why do I wheeze so much when I have asthma?

The quality and duration of wheezing also depend on where in the airways the obstruction is located. In asthma, the wheezing is due to narrowing of the lower airways, whereas, with malignancies, the obstruction is usually in the upper, more proximal airways.
