What is Ascites?

Ascites is the accumulation of fluid (usually serous fluid which is a pale yellow and clear fluid) that accumulates in the abdominal (peritoneal) cavity. The abdominal cavity is located below the chest cavity, separated from it by the diaphragm. Ascitic fluid can have many sources such as liver disease, cancers, congestive heart failure, or kidney failure.

What are the symptoms?

There may be no symptoms associated with ascites especially if it is mild (usually less than about 100 – 400 ml in adults). As more fluid accumulates, increased abdominal girth and size are commonly seen. Abdominal pain, discomfort, and bloating are also frequently seen as ascites becomes larger. Shortness of breath can also happen with large ascites due to increased pressure on the diaphragm and the migration of the fluid across the diaphragm causing pleural effusions (fluid around the lungs). A cosmetically disfiguring large belly, due to ascites, is also a common concern of some patients.
