Normally, only a small amount of lubricating fluid is present to allow smooth breathing movements, but when the fluid builds up excessively, it can cause breathing difficulties and discomfort. Pleural effusion is often a sign of an underlying disease and requires proper diagnosis and treatment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What is Pleural Effusion?<\/h2>\n\n\n\n<p>The pleura is a two-layered membrane: one layer covers the lungs, while the other lines the chest cavity. A small amount of fluid is normally present between these layers. When this balance is disturbed, <strong>pleural effusion<\/strong> occurs, leading to restricted lung expansion and reduced oxygen intake.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Causes of Pleural Effusion<\/h2>\n\n\n\n<p>Pleural effusion can result from a variety of conditions. The two main types are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Transudative Effusion (low-protein fluid):<\/strong><br>Caused by conditions that increase pressure or decrease protein levels in blood.\n<ul class=\"wp-block-list\">\n<li>Heart failure<\/li>\n\n\n\n<li>Cirrhosis of the liver<\/li>\n\n\n\n<li>Kidney disease (nephrotic syndrome)<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Exudative Effusion (high-protein fluid):<\/strong><br>Caused by inflammation, infection, or malignancy.\n<ul class=\"wp-block-list\">\n<li>Pneumonia (parapneumonic effusion)<\/li>\n\n\n\n<li>Tuberculosis<\/li>\n\n\n\n<li>Lung cancer, breast cancer, or metastatic cancers<\/li>\n\n\n\n<li>Pulmonary embolism<\/li>\n\n\n\n<li>Autoimmune diseases (like lupus, rheumatoid arthritis)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms of Pleural Effusion<\/h2>\n\n\n\n<p>Some patients may have no symptoms if the fluid buildup is small.
