Causes of a nocturnal cough can be categorized as respiratory, non-respiratory and systemic. . Other respiratory causes include bronchiectasis, bronchitis, chronic obstructive pulmonary disease (COPD), cystic fibrosis, interstitial lung disease (ILD), primary or secondary lung tumors, sarcoidosis, and tuberculosis. Other upper airway conditions to be ruled out are chronic tonsillar enlargement, obstructive sleep apnea, gastroesophageal reflux disease (GERD), laryngeal problems and foreign bodies in the large airways. Non-respiratory causes are GERD, recurrent aspiration, left ventricular failure, mitral stenosis, pulmonary infarction, and psychogenic a cough is a diagnosis of exclusion. Very rare conditions cardiac arrhythmias, aortic aneurysm, cough only when supine (due to a collapse of large airways), following complex involuntary tics (Tourette syndrome) and vitamin B12 deficiency (probably due to sensory neuropathy). Of all these conditions, cough variant asthma, GERD and upper airway cough syndrome (UACS) are called the pathogenic triad, and they constitute 90% cases.[2][3][4]
