Lung whitening is usually a sign of decreased lung translucency on imaging, and recovery is related to the severity of the disease. Lung whitening is often due to the fact that the alveoli and bronchioles of patients with pneumonia are filled with inflammatory secretions, with decreased translucency and higher density on imaging. Through systematic treatment, the body resistance is gradually strengthened, the inflammation is gradually eliminated, the gas re-enters the lungs, the white lungs gradually disappear, the transmittance becomes stronger and stronger, and some fibrous streaks may be left behind, etc., but it does not affect the normal life. However, in severe cases, respiratory failure and many other complications may occur, which may be life-threatening. If you feel unwell, you should go to the hospital in time, and under the guidance of the doctor, give targeted treatment after clarifying the cause.
