Why Am I Wheezing?

Wheezing happens when the airways are tightened, blocked, or inflamed, making a person's breathing sound like whistling or squeaking. Common causes include a cold, asthma, allergies, or more serious conditions, such as chronic obstructive pulmonary disease (COPD).

When should you go to the doctor for wheezing?

Seek emergency care if wheezing: Begins suddenly after being stung by a bee, taking medication or eating an allergy-causing food. Is accompanied by severe difficulty breathing or bluish skin color. Occurs after choking on a small object or food.

Is wheezing serious?

Wheezing is a high-pitched whistling sound made while you breathe. It's heard most clearly when you exhale, but in severe cases, it can be heard when you inhale. It's caused by narrowed airways or inflammation. Wheezing may be a symptom of a serious breathing problem that requires diagnosis and treatment.
