Wheezing, a high-pitched whistling sound that occurs when you breathe through narrowed breathing tubes, is a sign that you might be having breathing problems. While wheezing usually comes from the bronchial tubes, which are the small breathing tubes deep in your chest, it can sometimes be caused by a blockage in the larger airways, for example if you breathed in a foreign object.

To stop wheezing, you first have to find the source of the problem. There are many possible causes, including allergies (to a food, airborne allergen or insect bite or sting), asthma, bronchitis, pneumonia and other infections and smoking. Taking certain medications, particularly aspirin, may also cause wheezing. Wheezing can also be a sign of serious problems, such as heart failure, lung cancer and anaphylaxis, a severe and deadly allergic reaction. If you are wheezing, you should see your physician to help figure out the underlying cause of the symptom and how to treat it. If severe shortness of breath accompanies your wheezing, go immediately to the nearest emergency room.

One way to help alleviate your wheezing is to sit in an area where the air is moist and heated, such as a room with a vaporizer or a bathroom with a hot shower running. If the wheezing is caused by allergies, stay away from things you're allergic to. If you smoke, quit. No matter what the cause of your wheezing, make sure to take any and all medications your doctor prescribes. These may include taking corticosteroids or using a nebulizer or respiratory inhaler, which will help relax and open up your airways, allowing you to breathe more easily.
