Fifty years old, the two lungs texture increase, may be purely due to ageing and other physiological factors, may also be caused by bronchitis, bronchial asthma and other diseases, if caused by the disease for the cause of the need for anti-infective, cough and other treatments. Asymptomatic can be left untreated. Lung texture is the visualization of bronchial tubes, small arteries and veins, and lymphatic vessels in the lungs on imaging. The clinical significance of this imaging finding needs to be considered in the context of clinical symptoms. If the patient has fever, cough, sputum, etc., acute bronchitis or pneumonia can be considered, and common treatments include anti-infective (e.g., cefaclor, etc.), sputum (e.g., aminoglutethimide, etc.), and cough suppressant (e.g., pentoxyverine, etc.). If the patient is accompanied by shortness of breath, chest tightness, wheezing, etc., and has a history of bronchial asthma, it may be an acute attack of bronchial asthma, which needs to be treated with bronchodilators (e.g., salbutamol, etc.). If the patient does not have any clinical symptoms and simply has increased lung texture, which may be caused by aging, long-term smoking, environmental pollution, etc., the patient can be left untreated for the time being and be observed for a period of time and then reviewed. Specific drug selection and dosage should follow the doctor’s instructions.
