What is the increase in double lung markings?

Increased lung markings on both lower lungs are more than normal markings seen on chest X-ray or CT. At this time, acute bronchitis is most likely to be considered. If the patient is accompanied by cough, expectoration, shortness of breath and other manifestations, combined with clinical symptoms, acute bronchitis is likely to be considered. If the patient has no symptoms and is only found during physical examination, it may be increased physiological lung markings, which can be seen in obese people, elderly patients or congenital lung markings. At this time, no drug treatment is needed temporarily.
