Why pleural effusion

summary

There are many times, only when we understand why our body has problems, can we fundamentally solve the problem better and make the disease completely treated. We should have heard of pleural effusion, but why does it happen. Now I'll talk about why there is pleural effusion.

Why pleural effusion

First: any cause of pleural cavity appear too much liquid called pleural effusion, commonly known as pleural effusion. We often say that pleural effusion is actually pleural effusion. There are 3 ml ~ 15 ml liquid in the pleural cavity of normal people, which play a lubricating role in breathing movement, but the amount of effusion in the pleural cavity is not fixed. Even in normal people, 500ml-1000ml of liquid is formed and absorbed every 24 hours. The fluid in the pleural cavity is reabsorbed from the venous end of the capillaries, and the rest of the fluid is recovered from the lymphatic system to the blood.

Second: if the whole body or local lesions destroy the dynamic balance, resulting in pleural cavity fluid formation is too fast or absorption is too slow, clinical pleural effusion. According to the characteristics of pleural effusion, pleural effusion can be divided into leakage, exudate (serous or bloody), empyema, hemothorax, chylothorax.

Third: tumor (such as lung cancer, breast cancer, lymphoma, etc.) involving the pleura, making its surface permeability increased, or lymphatic drainage blocked, or accompanied by obstructive pneumonia involving the pleura, can cause exudative pleural effusion. Occasionally, chylothorax was formed due to obstruction of thoracic duct. If pericardial effusion occurs due to pericardial involvement, or the intravascular hydrostatic pressure increases due to obstruction of superior vena cava, or malnutrition hypoproteinemia due to malignant tumor, pleural effusion may be effusion.

matters needing attention

The above has told you why there is pleural effusion, I believe we all have a clear understanding. Usually must pay attention to their own body, do not because of busy work or distressed money do not go to see a doctor, must be timely discovery and treatment, can be in the most suitable time for treatment of the disease is treated, can recover better.
