👉 Cloudy fluid, often referred to as pleural effusion or ascites, is a mixture of clear fluid and cellular debris that accumulates in the space between the lungs (pleural cavity) or the abdominal cavity (peritoneal cavity). This fluid is primarily composed of water, proteins, and electrolytes, similar to normal pleural or peritoneal fluid. However, in cases of cloudiness, it may contain red blood cells, white blood cells, or other cellular components, indicating inflammation, infection, or tissue damage. The presence of cloudiness can suggest various underlying conditions, such as heart failure, liver disease, kidney dysfunction, or lung infections, and is typically evaluated through imaging tests like chest X-rays or ultrasounds.
