What is Cough?

Coughing is a vital mechanism to protect the respiratory tract and keep it free. But coughing can also be a symptom of many diseases, in particular those that affect the bronchial tubes and the lungs. The mucous membranes of the bronchial tubes are extremely sensitive to inflammatory stimuli and foreign bodies.

What types of cough do exist?

The way cough presents itself, its duration and its causes vary. For example, a cough that lasts longer than 8 weeks is called a chronic cough, otherwise it is called an acute cough. Furthermore, there is a difference between a dry cough and a productive cough. An irritating cough is called an unproductive cough. Coughing produces a barking-alike sound, often comes in bursts and makes restful sleep impossible. Normally, after a few days, dry cough turns into a cough that expels sputum from the body - a protective reflex that clears the airways and helps them to recover. Doctors refer to this as a productive cough.
