What is the significance of different cough types?
|Characteristic s of cough||Potential significance|
|Productive||Chronic bronchitis, lower respiratory tract infection, bronchiectasis or cancer.|
|Dry||Infection (upper or lower respiratory tract), asthma (see Evidence Box 2) (particularly nocturnal), gastro-oesophageal reflux disease, post-nasal drip, pulmonary fibrosis, drugs (e.g. ACE-inhibitors) or cancer.|
|Bovine||Vocal cord paralysis, potentially secondary to invasion of recurrent laryngeal nerve by lung cancer.|
|Wheezy||Airflow limitation, e.g. asthma (see Evidence Box 2).|
