Initially, white lungs are considered to be a symptom of inflammatory diseases in the lungs, but the possibility of diffuse alveolar hemorrhage syndrome, pulmonary fibrosis, lung cancer, etc. cannot be ruled out. Inflammatory lung diseases include viral pneumonia, lobar pneumonia, lung abscess, etc. Because the interstitial tissue of the lung is continuously stimulated by inflammation, the gas in the alveolar tissue may be replaced by inflammatory exudate, which causes exudative lesions and leads to white shadows in the lungs. Diffuse alveolar hemorrhage syndrome, pulmonary fibrosis, lung cancer and other conditions may also lead to diffuse lesions in the interstitial tissue of the lung, resulting in white shadows on lung imaging. It is recommended to go to a regular hospital for a more detailed examination to identify the specific cause of the disease before symptomatic treatment.
