How is pleurisy formed?

summary

Pleurisy is an inflammatory reaction of pleura caused by virus or bacteria and other pathogenic factors. Therefore, any disease that can stimulate pleura to cause inflammatory reaction can cause pleurisy. But different pleurisy is caused by different specific factors, pleurisy is how to form? Now let me tell you something.

How is pleurisy formed?

The pleura is divided into two layers, one is the pleura covering the surface of the lung, which is called visceral pleura, the other is the pleura covering the inner side of the chest, which is called parietal pleura. The two pleura together form a closed cavity, which is called pleural cavity. Under normal circumstances, the pleural cavity is completely closed, and there is only a small amount of serous in the cavity, which has lubrication effect, so that the friction effect of the two layers of pleura decreases with the movement of breathing. In the early stage of pleurisy, the inflammation infiltrates into the cavity, and in the late stage, the two layers of pleura adhere, affecting the respiratory movement.

The most common cause of pleurisy is pulmonary tuberculosis. Pleurisy caused by pulmonary tuberculosis becomes combined pleurisy. It is more common in children and adolescents because of pleural tuberculosis infection. The pathogenesis is that Mycobacterium tuberculosis and its metabolites stimulate the pleura and produce rapid inflammatory reaction

Other common lung diseases, such as pneumonia, lung abscess, spongy lung, etc., pneumonia inflammation infiltrating into the pleura can cause pleurisy, lung abscess can directly invade or break, stimulate the pleura to cause pleurisy. The focus of adjacent tissue such as mediastinal abscess, subphrenic abscess or liver abscess, abscess rupture makes pathogenic bacteria through the lymphatic tissue or directly invade the pleural cavity, stimulate the pleura and cause pleurisy.

matters needing attention

In order to prevent the occurrence of pleurisy, we should start from these causes and take preventive measures. In daily life, we should strengthen exercise, enhance the body resistance, have regular daily life, properly arrange work and rest, and don't be too tired. If you find physical discomfort, you should go to the hospital in time for treatment as soon as possible to avoid more serious complications.
