Definition:
Coughing is an important way to keep your throat and airways clear. However, excessive coughing may mean you have an underlying disease or disorder. Some coughs are dry, while others are considered productive. A productive cough is one that brings up mucus. Mucus is also called phlegm or sputum. Coughs can be either acute or chronic: - Acute coughs usually begin suddenly. They are often due to a cold, flu, or sinus infection. They usually go away after 2 to 3 weeks.
- Chronic coughs last longer than 2 to 3 weeks.
