Cough Treatment

What is cough

Cough is a useful reflex to clear your throat of mucous. It is also a protective reflex to prevent unwanted material from getting into your airway and lungs. Coughing from time to time is normal but if you cough frequently or if it lasts a long time it can become very distressing. Often people feel uncomfortable when they cough, as it draws unwanted attention to them, or it can cause disruption to sleep. 

If your cough lasts longer than 3 weeks it is classified as a chronic cough and it may suggest that you have an underlying abnormality of the lungs or airways. 

What causes chronic cough?

Many diseases of the lungs and respiratory system can cause a cough. These include:

  1. Asthma
  2. Emphysema
  3. Chronic Obstructive Pulmonary Disease (COPD)
