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 a mucus-like substance produced by the lower airways, such as the lungs and the respiratory system leading to the lungs, not by the nose and sinuses, which produce the mucus that streams out of or clogs up your nose. You may not notice phlegm unless you cough it up as a symptom of bronchitis or pneumonia.As is the case with mucus, phlegm that has a color such as green or yellow may indicate infection. Any time you see blood in the phlegm you cough up, you should seek medical attention. 3.
