Definition of Chronic Cough
A cough is a forceful ‘push’ of exhaled air that is either done voluntarily or as a reflex action (involuntary). A chronic cough is usually considered to be any cough that is persisting for more than 3 months. It may be constant, where the patient coughs every few minutes or it can be episodic, where a patient goes into a bout of coughing and it then subsides. A chronic cough is usually persistent because the cause of the cough may be a chronic disorder or the patient is constantly exposed to the same factors that may trigger the cough.
