Cough: Causes, Preventive Measures & Diagnosis



Cough is a natural reflex. The irritants present in your throat or lungs can go out of the body through it. Through coughing, your body repairs and protects itself. Most of the time, we cough to clear our throat but certain conditions can result in frequent coughing. 

Most of the coughing conditions will improve after 2 weeks. But you need medical attention if the cough persists for a longer duration. Also, you should seek a doctor's advice immediately if you notice some blood or a "barking" cough. 

Different Causes of Coughing

There are several reasons for coughing; let's discuss them one by one.

Need to Clear Your Throat

Such coughing is infrequent. However, it may increase if smoke particles surround you.

It is also a common cause of coughing. Smoking results in chronic cough with a distinct sound. It is also called a smoker's cough.


Coughing is common among young children who have asthma. Such a type of coughing involves wheezing, which makes it easy to identify.
