Wheezing describes the act of breathing with a whistling or rattling sound in the chest, usually due to narrowed or obstructed airways. Think of it as a squeaky sound coming from your lungs as you try to breathe. Unlike normal breathing, wheezing indicates difficulty in moving air through the respiratory system. It's often associated with conditions like asthma or bronchitis. It is similar to the sound produced by a poorly tuned wind instrument. The sound can be high-pitched or low-pitched.
