Whistling sound when I breathe out
You breathe out, and a high, thin whistle comes with the air. It may be soft, or loud enough for others to hear. Breathing in can feel fine, while breathing out feels slow.
Doctors call this sound a wheeze. It happens when air is pushed through narrow airways. The small tubes in your lungs can swell, tighten, or fill with mucus, a thick slime.
Asthma is one common reason for this sound. Colds, smoke, dust, pets, cold air, and hard exercise can all set it off. Some people only notice it at night, or after they laugh.
When to see someone
Call emergency help if you cannot finish a sentence, or your lips or nails look blue or grey. Go in at once if your face or tongue swells after a sting or a new food. See a doctor soon for a first wheeze, or one with fever, chest pain, blood in your cough, or swollen ankles.
Below you will find remedies people have used for asthma. Each one has an evidence grade, which shows how much research backs it. A high grade is not a promise, so talk to your doctor first, and keep taking any medicine you were given.
