Various Type of Cough

Coughs are necessary to expel foreign bodies and mucus from the trachea and airways of the lungs.

Coughing is a symptom rather than an illness, and can indicate sinusitis, croup, bronchitis, pneumonia, flu, viruses, the early stages of measles, asthma, whooping cough, or an excess of catarrh from the nose or sinuses, due to irritation or infection.

A dry cough may be caused by mucus from infections or colds, chemicals in the atmosphere, a foreign object or nervousness which constricts the throat.

A loose, wetter cough is caused by inflammation of the bronchial tubes produced by an infection or allergy. A constant nighttime cough, or one which recurs with each cold and is hard to get rid of, may indicate asthma.

Various terms describe the type of cough: An acute cough starts suddenly, and is usually resolved within a day or two. A chronic cough persists, sometimes for many weeks.

A productive cough brings up lots of catarrh or mucus. A nonproductive cough brings up very little or no mucus, and usually sounds harsh and hard.
