Wheezing

Wheezing is a high-pitched whistling sound made while breathing. It's often associated with difficulty breathing. Wheezing may occur during breathing out (expiration) or breathing in (inspiration).

Causes

Inflammation and narrowing of the airway in any location, from your throat out into your lungs, can result in wheezing. The most common causes of recurrent wheezing are asthma and chronic obstructive pulmonary disease (COPD), which both cause narrowing and spasms (bronchospasms) in the small airways of your lungs.

However, any inflammation in your throat or larger airways can cause wheezing. Common causes include infection, an allergic reaction or a physical obstruction, such as a tumor or a foreign object that's been inhaled.

Symptoms

The most common wheezing symptoms are a high-pitched sound that begins with breathing out (exhaling), shortness of breath, and a tight feeling in your chest.

Diagnosis

To diagnose what's causing wheezing, your doctor will ask questions about your symptoms and medical history and do a physical exam. The doctor may order several tests to determine the cause of wheezing.

Treatment

Treatment for wheezing depends on the underlying cause. In most cases, medications are prescribed to open the airways and reduce inflammation.
