3 common reasons for chronic cough

Chronic cough is most commonly caused by one of three conditions:

Upper airway cough syndrome (UACS): Post-nasal drip accompanied by frequent nasal drainage and throat-clearing can have several causes, including allgergic rhinitis and chronic sinusitis. Allergic rhinitis may be due to airborne allergies (like pollen), irritants (like tobacco smoke), infections (like the common cold) or swelling and congestion caused by blood vessel dilation (vasomotor rhinitis). Chronic sinusitis involves sinus inflammation and drainage.
Asthma: Cough is sometimes the only sign of asthma. Called “cough-variant asthma,” this condition stems from airway inflammation.
Gastroesophageal reflux disease (GERD): If you have heartburn or a sour taste in your mouth, your cough may be caused by acid back-up into the esophagus. “Some patients do not have classic symptoms of GERD, but their cough can be related to reflux,” notes Dr. Taliercio.

Less common causes of chronic cough include non-infectious bronchitis unrelated to asthma and laryngeal reflux (acid back-up into the throat and voice box).

And to complicate things a bit, “it’s not uncommon to have more than one reason for your chronic cough,” says Dr. Taliercio.

怎么治？

If you have UACS or asthma, you should experience a 50 percent reduction in your cough within a few weeks of treatment. If you have GERD, it may take several months for anti-reflux therapy to work.

Using this approach works for the majority of patients Dr. Taliercio and Paul Bryson, MD (an ear, nose and throat specialist), see in their Chronic Cough Clinic.
