WheezingÂ
Wheezing refers to a high-pitched whistling sound made when someone breathes. In general, it is heard when that person exhales but in severe cases, and it can easily be heard when he/she inhales, too. Wheezing actually comes from inflammation or narrowed airways.
Wheezing is definitely not a symptom to be ignored as it can signal serious diseases, including COPD. However, don’t rush into making any assumptions. Wheezing can also be caused by a reaction to smoking or bronchiolitis, a common viral respiratory infection.
Don’t ignore this noise when you’re breathing! Please inform your doctor about it as soon as possible.
