Night cough has several airway and reflux pathways
Lying-down cough may involve asthma, upper-airway secretions, reflux or other causes depending on associated features.
Several explanations may be worth exploring
- Upper-airway cough syndromeNasal or pharyngeal symptoms may contribute to chronic cough.
- Cough-variant asthmaAirway hyperresponsiveness may cause cough without obvious wheeze.
- Nonasthmatic eosinophilic bronchitisAirway eosinophilia may cause cough despite normal standard spirometry.
- Reflux-associated coughEsophageal symptoms or laryngeal irritation may coexist with cough.
- Cough hypersensitivity syndromeSensory nerves can overreact to speech, scents and temperature changes.
Interpret what was testedA complete medicine list matters because some common therapies cause cough despite a clear chest X-ray.
An important alternative interpretationA reassuring test only answers the question that test was designed for; discussing its limits may guide the next step.
It is fine not to rememberBring the original report, medication labels and relevant dates rather than guessing from memory.
A clue beyond the main symptomNasal, reflux and wheeze clues influence which clinical causes are considered rather than proving any one of them.
This could change prioritizationThe timing of this detail alongside the main symptom can influence which questions are asked next.
Something to mention in the reviewYour doctor can help decide whether the accompanying finding is connected or coincidental.
No extra clue is also usefulNot recognizing another clue does not exclude any particular cause.
