Understanding the types of coughs

Coughing, also known as tussis, is a voluntary or involuntary action that clears the throat and breathing passage of foreign particles, bacteria, irritants, fluids, and mucus; it is a fast expulsion of air from the lungs.

There are several kinds of coughs, each with particular features that can assist your doctor in determining what underlying condition is causing it. A productive cough is one that produces phlegm or mucus and may indicate pneumonia, bronchitis, or the flu. The color of the mucus might indicate a more serious issue. A dry or nonproductive cough is one that does not generate mucus.

The most common form of cough is acute cough. It only lasts three weeks or less and will eventually subside on its own. This form of cough does not necessitate medical care. Coughs that continue for more than eight weeks might be an indication of a more serious or chronic lung illness.
