Complications of cirrhosis include ascites, which can be treated with salt restriction, diuretics, and paracentesis. Esophageal variceal bleeding is treated with nonselective beta blockers or TIPS. Hepatic encephalopathy was thought to be worsened by high-protein foods but studies show this is incorrect. Hepatorenal syndrome is defined as renal failure with low urine sodium and high serum creatinine in cirrhosis patients. People with ascites due to cirrhosis are at risk for spontaneous bacterial peritonitis. Cirrhosis can also cause portal hypertensive gastropathy, immune dysfunction leading to infection, and hepatocellular carcinoma.
