Wheezing is a whistling sound when you breathe, from narrowed airways. It is common in asthma and chest infections, and occasionally an emergency.
No — infections, COPD, allergy and reflux can all cause wheeze. New or recurrent wheeze should be assessed to find the cause.
If it comes with severe breathlessness, blue lips, an inability to speak in full sentences, or signs of an allergic reaction, call emergency services.
