Report Abuse. A cough is a reflex when we're ill. This is going to sound pretty disgusting but extra mucus is produced during illness to catch any bacteria and stop more of whatever's made you ill from entering your body, and you cough it back up regularly to stop the mucus from entering your lungs and choking you.
A cough may be described as being dry, wet, productive (meaning you cough up mucus and/or sputum), or non-productive. Even the way a cough sounds can give us a pretty good clue as to what is going on. A dry cough may be caused by an allergy, cold, flu, or the beginning of bronchitis. A wet, productive cough could be the result of pneumonia, bronchitis, or the flu. A wet, nonproductive cough may also suggest a cold, flu, or bronchitis. A painful cough is frequently seen with pneumonia or bronchitis.
