Edema and ascites. Liver failure causes fluid buildup that results in edema and ascites. Ascites can lead to spontaneous bacterial peritonitis, a serious infection that requires immediate medical attention.
Hepatic encephalopathy. A failing liver cannot remove toxins from the blood, so they eventually accumulate in the brain. The buildup of toxins in the brain is called hepatic encephalopathy. This condition can decrease mental function and cause stupor and even coma. Stupor is an unconscious, sleeplike state from which a person can only be aroused briefly by a strong stimulus, such as a sharp pain. Coma is an unconscious, sleeplike state from which a person cannot be aroused. Signs of decreased mental function include
confusion
personality changes
memory loss
trouble concentrating
a change in sleep habits
