While Colds and the flu are the most common causes of coughing, it can also happen due to allergies, throat irritants, drugs or underlying medical conditions.
Types of Cough
The action of coughing expels mucous, germs, and dust particles from the airways, defending the lungs from infection and swelling.
Cough marks the defence of the body against disease. There are usually two types of cough. A dry cough and a wet cough.
Dry Cough

A dry cough is not productive i.e. no sputum is produced in the disease. It can be as a result of an allergic reaction in the throat. Also, a persistent dry cough can be a result of gastroesophageal reflux disease, asthma, lung cancer, heart failure or some medication side effects.
