Wheezing refers to the whistling sound you involuntarily make while breathing. This sound is generally heard while breathing out, but sometimes you may also hear it when you are breathing in. Although wheezing is usually an indication of a breathing problem such as bronchitis, COPD or asthma, it may also be caused because of blockage in the large airways of the lungs, or if there is a problem with the vocal chords.

Wheezing is easily treatable with the right kind of medication. There is no reason to worry, because modern medicine has made it possible to completely control and treat most of the breathing problems.
