Most of the patients will be cured by themselves, for example, the thickening and increase of lung texture caused by exercise or viral infection will be cured by themselves, while the thickening and increase of lung texture caused by bronchopneumonia will not be cured by themselves. 1. Exercise: generally refers to the thickening and increase of lung texture caused by strenuous exercise, running and so on, which belongs to physiological factors and can be cured after rest. 2. Viral infection: If acute bronchitis caused by viral infection leads to thickening and increasing of lung texture, it is self-limiting and can be cured. 3. Lung inflammation: If bronchopneumonia is caused by lung infection, resulting in thickening and increasing of lung texture, it can’t be cured by itself and needs to be treated as soon as possible in order to be cured. If the thickening and increase of lung texture may be caused by different factors, you need to cooperate with professional doctors as soon as possible to improve the next step of the examination, to clarify the cause, to determine whether to treat.
