Chronic Cough

A cough that lasts 8 weeks or longer is known as a chronic cough. A chronic cough is not a disease itself. It is a sign of something wrong.

Some of the causes of chronic cough include:

• Post-nasal drip syndrome
• Something at home or work that is irritating your nose or airway
• Allergies
• Asthma
• Smoking
• COPD (chronic obstructive pulmonary disease)
• Acid reflux
• Some high blood pressure medications
• A combination of these causes.

In some cases, chronic cough can be caused by serious diseases like tuberculosis (TB) and lung cancer.
