Cirrhosis is a condition in which your liver is scarred and permanently damaged. Scar tissue replaces healthy liver tissue and prevents your liver from working normally. As cirrhosis gets worse, your liver begins to fail.
Cirrhosis has many signs and symptoms, such as fatigue and severe itchy skin. They may not appear until the liver is badly damaged. Causes include alcoholic liver disease, nonalcoholic fatty liver disease, chronic hepatitis C, and chronic hepatitis B.
Doctors diagnose cirrhosis based on your medical history, a physical exam, and the results of tests. Tests include blood tests such as liver function tests and tests for viral infections, imaging tests, and liver biopsy.
Doctors do not have specific treatments that can cure cirrhosis. However, they can treat many of the diseases that cause cirrhosis. Treating the underlying causes of cirrhosis may keep your cirrhosis from getting worse and may help prevent liver failure.
If you have cirrhosis, you should eat a healthy, well-balanced diet. Talk with your doctor, a dietitian, or nutritionist about healthy eating. Avoid foods and drinks that can damage your liver, such as shellfish and alcohol.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and other components of the National Institutes of Health (NIH) conduct and support research into many diseases and conditions.
