Does infantile pneumonia have phlegm symptom?

Coughing is a defensive reflex movement that prevents foreign body inhalation. In dry weather, dust more winter and spring, the baby is easy to inhale dust and other particles, or infection caused by a series of inflammation and cough. If the parents ignore the treatment and do not heal for a long time, the baby's cough will develop from "exogenous" to "internal injury".

Accumulated particles or inflammation constantly stimulate the mucosa of bronchial wall for a long time, causing congestion and edema of the mucosa. At this time, the mucosa will start the self-healing mode, secrete more mucus, and the wall will become thicker and thicker. However, children's respiratory system is still immature, the airway lumen is narrow, the cilia movement is poor, and the strength of respiratory muscles is weak, so sputum is more difficult to discharge than adults.

More and more mucus builds up, making the lumen narrower or completely blocked! Once the "difficult" sputum and bacteria accumulate in the respiratory tract, it is easy to cause bacteria to spread down to the trachea, bronchus and lungs. Inflammation can also lead to the thickening of small pulmonary vascular intima, the decrease of blood flow, and the decrease of alveolar wall elasticity due to the decrease of blood supply. If there is no effective treatment, the "injured" lung will be targeted by virus, bacteria or mycoplasma, and develop into pneumonia.
