When is a cough considered to be chronic?

A chronic cough is considered to be a cough that lasts eight or more weeks in adults and four weeks in children. A very severe chronic cough can disrupt sleep, cause lightheadedness, headache and vomiting, and in some cases, it may even result in broken ribs.

What causes a chronic cough?

The most common causes of chronic cough include:

• smoking

• gastroesophageal reflux (GERD), backflow of stomach acid into the lower esophagus

• asthma, especially during flare-ups

• post-nasal drip

• COPD (chronic obstructive pulmonary disease)

• chronic bronchitis

• infections

• certain medications

A chronic cough is often associated with other symptoms such as stuffy nose, runny nose, hoarseness, heartburn, shortness of breath, sore throat and a frequent need to clear your throat. It may also become worse at night or any time you recline, as well as during and after periods of exertion.

How is a chronic cough diagnosed?

A chronic cough can have many underlying causes, which makes diagnosis a critical part of treatment. Diagnosing the cause of a chronic cough relies on a physical exam and personal history, a review of lifestyle habits, imaging tests like x-ray or CT scan, lung function tests or blood work. A thin, flexible tube called an endoscope may also be used to look inside the airways for possible causes.

How is a chronic cough treated?

Treatments for a chronic cough are based on the underlying cause and can include:

• decongestants

• antihistamines

• asthma medication

• acid blockers to treat GERD

• cough suppressants

• antibiotics to treat infections

Lifestyle changes like quitting smoking and avoiding allergens can also help. If you have a chronic cough, getting treatment as soon as possible is important for avoiding serious side effects and maintaining optimal health and wellness.
