Chronic Cough Is a cough of unexplained cause persisting for 8 weeks or more, it is the commonest cause for referral to our respiratory clinics. There are many possible causes but very few turn out to be due to serious underlying disease.
Many of the conditions described elsewhere are of course associated with coughing. Other features may give a clue as to the underlying problem, but often simple investigations are necessary.
In most of the patients we see when we have excluded other structural diseases of the lung, symptoms are due to asthma predominantly presenting as cough, reflux disease where there is reflux of the stomach into the gullet or oesophagus, and sometimes sinus related problems from the sinuses around the nose. In all of these situations treatment can be offered to help.
