Wheezing is a high-pitched whistle that occurs with breathing. It usually occurs during an asthma attack, lung disease or when a foreign object reaches the lungs. Allergic reactions, smoking, acid reflux, and heart failure can also cause wheezing.
Aspirin, NSAIDs, beta-blockers and antibiotics can increase the risk of an asthma attack or an allergic attack which may include wheezing.
Treatment for wheezing in an emergency may include using an asthma inhaler or an epinephrine injection for an allergy. For mild wheezing, home treatments include breathing in warm, moist air. Avoiding smoking, drinking hot liquids and doing breathing exercises can also help.
Diagnosing the cause of a case of wheezing may require a physical exam, chest X-rays, lung exams, and blood tests.
A word from Verywell
Wheezing can be uncomfortable and even scary, but the good news is that it’s possible to identify the cause and prevent further cases. In children, wheezing is often caused by an infection, which can also be treated. If you experience wheezing for the first time, it is advisable to seek emergency care to rule out any life-threatening conditions like allergies or an asthma attack.
Frequently Asked Questions
Is wheezing dangerous?
Wheezing can be dangerous if its cause is unknown or left untreated in severe cases. In the event of an allergy or an asthma attack, it is crucial to seek treatment with an inhaler or an injection of epinephrine. In less severe cases, wheezing can be treated at home, as it’s likely caused by a cold or other viral infection (especially in children).
Can wheezing be treated at home?
If wheezing is caused by an infection or a cold, the condition can be treated at home. Sitting in warm, moist air, such as in a steamy bathroom or next to a vaporizer, can help relieve discomfort. Avoiding allergens, smoke, and cold air might also help, as might drinking hot liquids. For children, keeping them calm can be helpful. If your wheezing gets worse, see a doctor right away.
Is wheezing a symptom of COVID-19?
Wheezing can be a symptom of COVID-19 in some people, especially those with asthma. Shortness of breath is also a symptom of both conditions.
However, unlike asthma attacks, COVID-19 can also be accompanied by fever, swelling, rash, loss of taste, or mild nasal congestion.
