Possible Causes of Chronic Cough
There are many possible causes of cough. Most of the possible causes of cough can be grouped into four main categories:
Both asthma and bronchitis can cause cough. Breathing tests can help rule out asthma but breathing tests are often normal with bronchitis. Neither of these conditions shows up on a chest x-ray. However, other chest conditions can show up on chest x-ray. Therefore, we frequently order a chest x-ray to evaluate chronic cough.
Nasal and sinus conditions can also cause cough. Therefore, we sometimes order sinus x-rays or initially just a trial of nasal or sinus medication.
GERD (Gastro-Esophageal Reflux Disease) or LPR (Laryngo-Pharyngeal Reflux) can also trigger chronic cough. If there is no sign or symptoms of nasal, sinus, or chest condition, we sometimes prescribe a trial of medicine to treat possible GERD or LPR.
Lastly, cough may persist as a result of a learned habit. This is not an intentional behavior but rather a habit over which the individual has no sense of control. This cough is sometimes responsive to behavior modification therapy or suggestive therapy.
