What do I need to know about wheezing?
Wheezing happens when air flows through a narrowed or blocked airway. Wheezing can happen when you breathe in, breathe out, or both. Wheezes may sound like a whistle, squeal, groan, or creak. Wheezes may also sound musical or high-pitched.
What causes or increases my risk for wheezing?
- Asthma
- Allergies
- A respiratory or sinus infection
- Extra mucus in sinuses or airways
- Smoking, or exposure to secondhand smoke
- Certain medical conditions such as chronic obstructive pulmonary disease (COPD)
- A foreign body blocking your airway passages
What are the signs and symptoms of wheezing?
- Noisy breathing
- Shortness of breath
- Chest tightness
- Fast breathing or heart rate
- Cough
How is wheezing diagnosed?
- An x-ray or CT of your chest may show the cause of the wheezing. You may be given contrast liquid to help the lungs show up better in the pictures. Tell your healthcare provider if you have ever had an allergic reaction to contrast liquid.
- Blood tests may show infection, blood oxygen levels, and antibody levels.
- Breathing tests may show how your airways are working. Pulmonary function tests (spirometry) or peak flow can show if your airways are narrowed or blocked.
- A sputum sample may show if your wheezing is caused by a bacterial infection.
How is wheezing treated?
- Medicines may help open your airways, decrease your symptoms, or treat an infection. They may be given as an inhaler, nebulizer, or pill.
- You may need extra oxygen if your blood oxygen level is lower than it should be. You may get oxygen through a mask placed over your nose and mouth or through small tubes placed in your nostrils. Ask your healthcare provider before you take off the mask or oxygen tubing.
Treatment options
The following list of medications are related to or used in the treatment of this condition.
How can I manage my symptoms?
- Return to your usual activity as directed. You may need to limit certain activities. Ask your healthcare provider when it is okay to resume activity.
- Take deep breaths and cough several times a day. This will decrease your risk for a lung infection and help decrease wheezing. Take a deep breath and hold it for as long as you can. Let the air out and then cough strongly. Deep breaths help open your airway. You may be given an incentive spirometer to help you take deep breaths. Put the plastic piece in your mouth and take a slow, deep breath in, then let the air out and cough. Repeat these steps 10 times every hour.
- Drink liquids as directed. You may need to drink more liquids than usual to thin your mucus and prevent dehydration. Ask how much liquid to drink each day and which liquids are best for you.
How can I help prevent wheezing?
- Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Avoid allergy triggers , such as animals, grass, pollen, or dust.

- You feel lightheaded, short of breath, and have chest pain.

- You have sudden trouble breathing.
- Your throat feels like it is swelling or feels tight.
