Wheeze

(En español: Sibilancia)

Say: weez

A wheeze is the whistling sound air makes when your breathing tubes are narrowed. This is what happens during an asthma flare-up. If the breathing tubes get too narrow, a person may have trouble breathing. Sometimes you can hear someone wheeze, but usually a doctor needs to listen to a person's lungs with a stethoscope to hear wheezing.
