Cirrhosis is advanced scarring of the liver resulting from a variety of conditions. These include chronic viral hepatitis, liver disease, nonalcoholic fatty liver, autoimmune or genetic disorders, and bile duct problems. Healthy liver tissue is replaced by fibrous nodules, distorting blood flow and impairing function. Many show no symptoms for years; early recognition of risk factors is critical.
A list of symptoms includes fatigue, weakness, loss of appetite, nausea, easy bruising or bleeding, jaundice (yellowing of skin and eyes), itchy skin, fluid buildup in the abdomen (ascites), swelling in legs and ankles (edema), confusion or memory problems (hepatic encephalopathy), spiderlike blood vessels on the skin (spider angiomas), red palms (palmar erythema), dark urine, pale or tar-colored stools. As scarring advances, warning signs of decompensation can appear: jaundice, confusion or sleep–wake reversal from hepatic encephalopathy, gastrointestinal bleeding from enlarged esophageal or gastric veins (varices), and severe abdominal distension from ascites. These developments signal complications that require prompt medical care. (Cleveland Clinic)
Clinicians diagnose cirrhosis by combining history and examination with blood tests, imaging such as ultrasound or elastography to assess stiffness, and sometimes liver biopsy to confirm stage or clarify cause. Ultrasound also screens for portal hypertension and liver cancer. Routine labs may show low platelets, elevated bilirubin, and abnormal clotting; scoring systems help categorize severity and guide decisions about surveillance, medications, and transplant referral.

Liver cirrhosis generally progresses through four main stages, each marked by increasing damage and complications, outlined in the following list. In the compensated stage, scar tissue is forming but the liver still performs most of its functions, so many people have few or no symptoms beyond mild fatigue or occasional discomfort. The disease then moves into compensated with varices, where blood flow through the liver is restricted enough to cause enlarged veins (varices) in the esophagus or stomach, which can bleed if not managed. As damage advances to the decompensated stage, serious complications develop—such as ascites (fluid buildup in the abdomen), jaundice (yellowing of skin and eyes), hepatic encephalopathy (confusion and memory issues), and significant bleeding from varices. Finally, end-stage liver disease occurs when liver function is severely impaired and life-threatening complications such as liver failure, infection, or liver cancer become likely, often making liver transplantation the only treatment option.
Complications arise from both scarring and altered blood flow. Portal hypertension can cause varices and splenomegaly; fluid accumulation leads to ascites and edema; infections such as spontaneous bacterial peritonitis can occur in those with ascites; kidney dysfunction may emerge as hepatorenal syndrome; and thinking changes reflect buildup of toxins the liver can no longer clear. Cirrhosis also raises the risk of hepatocellular carcinoma, so regular imaging surveillance is recommended once the diagnosis is established. (NIDDK)
Treatment focuses on two goals: addressing the underlying cause to slow or halt further scarring, and managing complications to preserve quality of life. Disease-specific measures may include antiviral therapy for hepatitis B or C, complete alcohol abstinence and treatment for alcohol use disorder, weight loss and metabolic care for fatty liver disease, immunosuppression for autoimmune hepatitis, or relieving bile duct obstruction in cholestatic diseases. Vaccination against hepatitis A and B, and staying up to date on routine immunizations, help prevent additional liver injury. (MedlinePlus)
Managing complications is highly individualized. Diuretics and sodium restriction are mainstays for ascites; large-volume paracentesis and albumin may be added for tense fluid. Nonselective beta-blockers and endoscopic band ligation reduce the risk of variceal bleeding, while urgent endoscopy treats active hemorrhage. Lactulose—with or without rifaximin—helps prevent and treat hepatic encephalopathy by lowering ammonia levels. Nutrition support emphasizes adequate protein and calories to counter muscle loss, with attention to alcohol cessation and avoidance of medications that can harm the liver. (NIDDK)
Prognosis varies with cause, stage, and response to treatment. When the underlying driver is treated early—curing hepatitis C, sustaining abstinence from alcohol, or reversing metabolic risk—scarring can stabilize and, in some cases, partially regress. Decompensated cirrhosis carries a higher risk of hospitalization and mortality, underscoring the importance of early intervention, vaccinations, nutrition, and consistent specialty care. With a clear plan that targets the cause, monitors for cancer and bleeding, and addresses complications promptly, many people live longer and better despite chronic liver disease.
