How coughing is diagnosed?

Whether a particular factor is responsible for chronic coughing can be determined when treatment for a specific cause achieves some benefit for the patient. But often there is more than one cause for the cough, in which case treating only one factor will not succeed in completely relieving the symptoms. To determine the cause of a cough, a physician should take an exact medical history and perform an exam. Information regarding the duration of the cough, what other symptoms may accompany it, and what environmental factors may influence it aid the doctor in his or her diagnosis. The appearance of the sputum will also help determine what type of infection, if any, may be involved. The doctor may even observe the sputum microscopically for the presence of bacteria and white blood cells. If the cause of cough is not strongly suspected based on the history and physical examination alone, a chest x-ray is done in most patients at least once during the evaluation of cough to ensure that there are no structural abnormalities in the lung which might be causing the cough. Unusual causes of cough can include benign tumors of the lung, bronchiectasis, "habit" cough, foreign body in the lung, and interstitial lung disease.
