What Causes Throat Mucus & Phlegm? Post Nasal Drip:Post nasal drip occurs when an excessive amount of mucus accumulation in the nose and throat creates phlegm and causes coughing. Cold or Flu: During a cold or the flu, there is a production of clear, thin mucus in the nose and back of the throat.
Phlegm is more related to disease than is mucus and can be troublesome for the individual to excrete from the body. Phlegm is a secretion in the airway during disease and inflammation. Phlegm usually contains mucus with virus, bacteria, other debris, and sloughed-off inflammatory cells.
