Signs and Symptoms
Both types of hepatorenal syndrome share three major components: altered liver function, abnormalities in circulation, and renal failure. As these phenomena may not necessarily produce symptoms until late in their course, individuals with hepatorenal syndrome are typically diagnosed with the condition on the basis of altered laboratory tests. Most people who develop HRS have cirrhosis, and may have signs and symptoms of the same, which can include jaundice, altered mental status, evidence of decreased nutrition, and the presence of ascites. Specifically, the production of ascites that is resistant to the use of diuretic medications is characteristic of type 2 HRS. Oliguria, which is a decrease in urine volume, may occur as a consequence of renal failure; however, some individuals with HRS continue to produce a normal amount of urine. As these signs and symptoms may not necessarily occur in HRS, they are not included in the major and minor criteria for making a diagnosis of this condition; instead HRS is diagnosed in an individual at risk for the condition on the basis of the results of laboratory tests, and the exclusion of other causes.

—Jimmy Carter (James Earl Carter, Jr.)
“Murderous desire, hatred, distrust are nowadays the accompanying signs of physical illness: so thoroughly have we embodied our moral prejudices.—Perhaps cowardice and pity appear as symptoms of illness in savage ages. Perhaps even virtues might be symptoms.”
