Cough is an independent disorder or symptom of many disorders. A cough is a sudden expulsion of air through the mouth that can help clear of fluids, irritants, foreign particles and microbes.
Types of cough:
- Dry coughs commonly follow on from respiratory illnesses. These coughs develop when there is little or no mucus in the throat. A person may feel a tickling sensation in their throat and be unable to stop coughing.
- Wet cough occurs when a person coughs up mucus or phlegm. Wet coughs are typically due to an infection, such as the flu, the common cold, or a chest infection.
- Chronic Cough- A cough that lasts longer than a typical illness, usually 8 weeks or more.
