Wheezing is a high-pitched whistling sound during breathing. It occurs when air moves through narrowed breathing tubes.
Wheezing is a sign that a person may be having breathing problems. The sound of wheezing is most obvious when breathing out (exhaling), but may be heard when taking a breath (inhaling).
Wheezing most often comes from the small breathing tubes (bronchial tubes) deep in the chest, but it may be due to a blockage in larger airways or in persons with certain vocal cord problems.
Always take all of your medications as directed.
Sitting in an area where there is moist, heated air may help relieve some symptoms. This can be done by running a hot shower or using a vaporizer.
