Chylous ascites has a milky appearance caused by lymph that has leaked into the abdominal cavity. Although chylous ascites is sometimes caused by trauma, abdominal surgery, tuberculosis , or another peritoneal infection, it is usually a symptom of lymphoma or some other cancer . Endocrine and renal ascites are rare disorders. Endocrine ascites, sometimes a symptom of an endocrine system disorder, also affects women who are taking fertility drugs. Renal ascites develops when blood levels of albumin dip below normal.
Albumin is the major protein in blood plasma.
It functions to keep fluid inside the blood vessels. This change in pressure allows fluid to seep out of the blood vessels. Portal hypertension is caused by the scarring that occurs in cirrhosis. Blood that cannot flow through the liver because of the increased pressure leaks into the abdomen and causes ascites. Persons who have systemic lupus erythematosus but do not have liver disease or portal hypertension occasionally develop ascites.
