What should I do if the lung texture becomes thicker in the physical examination of New Zealand study visa?

First of all, there is no objective and quantifiable standard for pulmonary texture thickening, which is related to the health status of the subject, photo factors and the personal experience of the diagnostician. Secondly, there are many reasons for the thickening of lung texture, which can be pathological, physiological or technical. Generally speaking, isolated reports of pulmonary thickening have little clinical value. Only by carefully analyzing the nature of increased lung texture and combining with other X-ray manifestations, clinical conditions and technical conditions can we draw a correct conclusion. In other words, the thickening of lung texture without any clinical symptoms is completely physiological, that is, completely normal. If you have respiratory symptoms, consider bronchitis. And need anti-inflammatory treatment.
