If yes: ask about severity and if this has caused them to be admitted to hospital (for example an exacerbation of asthma requiring admission).

Gastrointestinal causes:
Gastro-oesophageal reflux disease (GORD): cough worse with certain foods e.g spicy, heartburn symptoms, sensation of something stuck in throat.
Investigation:
Bedside: respiratory examination, Oxygen saturation (SPO2), pulse/heart rate (HR), blood pressure (BP), respiratory rate (RR)
Bloods : full blood count (FBC), urea and electrolyte (U&E), c-reactive protein (CRP) + Erythrocyte Sedimentation Rate (ESR) and Brain natriuretic peptide (BNP)
