Yellow effusion born in the lungs generally refers to pleural effusion, which can be considered as pneumonia, lung abscess, tuberculous pleurisy, and lung tumors.
In patients with pneumonia, lung abscess, tuberculous pleurisy, and lung tumors, the endothelial cells of the blood vessels are damaged due to toxins of pathogenic microorganisms, tissue hypoxia, and inflammatory mediators, resulting in an increase in the permeability of the blood vessels to the point that macromolecular substances in the blood, such as serum proteins, globulins, and fibrous proteins, as well as a wide variety of cellular components can leak out of the walls of the vessels, and a pleural effusion of yellowish color can occur.
When pleural effusion occurs, it may also be seen in rheumatic diseases, cardiac insufficiency, low-protein nephropathy, moderate malnutrition and other diseases, which need to consult the doctor in time, draw pleural fluid for laboratory tests, X-ray, ultrasound, chest CT, blood routine and other auxiliary examinations to find out the cause of the disease, and then to treat the cause of the disease.
In life, it is necessary to strengthen exercise, light diet, eat more vegetables and fruits and avoid smoking and alcohol.
