Chronic Cough

Chronic cough is usually caused by: Asthma, Chronic rhinitis with post-nasal drip, and acid reflux. Outlined below is a quick overview of each of these three common causes:

Asthma

Diagnosis is based on clinical history in conjunction with breathing tests like spirometry.

Chronic Rhinitis with Post-Nasal Drip

Symptoms include itchy throat, a bad taste in the mouth or the feeling like something is caught in the throat. Postnasal drip is a very common symptom of allergic rhinitis or sinusitis. Identification of possible allergies and treatment of allergy symptoms, and treatment of sinusitis if present, is essential to treat cough caused by post nasal drip.

Acid Reflux (Laryngopharyngeal Reflux)

While most people think of heartburn as the main symptom of GERD, three of four patients with GERD will suffer from a chronic cough, with or without heartburn symptoms. GERD is best treated with a combination of lifestyle changes, dietary changes and medication.
