Wheezing: How to Recognize, Treat, and Respond
You’ve probably heard the term wheezing—that whistling, musical sound that happens when air struggles to move through narrowed airways. But here’s what many people don’t realize: children may wheeze when they have viral infections or something called bronchiolitis. Children who have diseases that cause wheezing over and over again are more likely to develop asthma too.
What Wheezing Sounds Like
Wheezing often sounds like:
A high-pitched whistling or squeaking sound, especially when you exhale.
Sometimes audible only with a stethoscope (which is why I usually make you come in if I suspect it)
Often accompanied by tightness in your chest, coughing, or shortness of breath (can be one or all).
Listen to examples from the American Lung Association:
➡️ What Wheezing Sounds Like
Common Causes
While asthma is one of the most frequent causes, wheezing can also occur with:
Viral infections (especially in children)
Allergies or exposure to irritants (smoke, dust, strong scents)
Acid reflux (GERD) irritating the airway
Bronchitis or COPD
Anaphylaxis or airway swelling (a medical emergency)
What to Do When You Wheeze
Stay calm. Try slow, steady breathing through pursed lips.
Avoid triggers. Step away from smoke, allergens, or cold air.
Use your rescue inhaler (if prescribed).
Monitor symptoms. Note how long it lasts, what triggered it, and whether your inhaler helped.
When to Seek Care
Call your doctor or urgent care if:
Wheezing is new or worsening despite taking steps above
You have no asthma diagnosis
Your rescue inhaler isn’t working, has expired, or is non-existent
You experience shortness of breath at rest or during conversation
Go to the ER or call 911 if:
You can’t speak in full sentences
Your lips or fingertips turn blue
Your chest feels tight or “stuck” despite using your inhaler
Breathe Easier with Awareness
Recognizing wheezing early can help prevent severe flare-ups. Whether caused by asthma, allergies, or something else, don’t ignore the signal your body is sending—it’s asking for attention.
