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.
