Cirrhosis: scarring of the liver explained
Damage that is slow, silent, then sudden
Dr. Marc Delaunay
Gastroenterologist

In simple terms
The causes that still dominate, the complications to watch, and what can be reversed.
What it is, in plain words
Cirrhosis is the end result of years of liver injury. Repeated inflammation replaces working liver cells with scar tissue, which both reduces liver function and blocks blood flowing through the organ. That back-pressure, called portal hypertension, causes most of the visible complications.
Signs to look out for
- No symptoms at all for years, the compensated stage
- Fatigue, poor appetite and weight loss
- Yellow eyes and skin, itching, easy bruising
- Swollen abdomen from fluid, and swollen legs
- Confusion, drowsiness and reversed sleep pattern from toxins reaching the brain
Why it happens
The leading causes are chronic alcohol use, fatty liver disease linked to obesity and diabetes, and chronic hepatitis B or C. Less common ones include autoimmune hepatitis, haemochromatosis, Wilson disease and bile duct diseases.
How doctors confirm it
Blood tests show falling albumin and platelets and rising bilirubin and INR. Elastography measures liver stiffness without a needle. Ultrasound, and sometimes biopsy, confirm the picture. Endoscopy looks for varices in the gullet, and six-monthly ultrasound screens for liver cancer.
Treatments and solutions
- Removing the cause: complete alcohol abstinence, antiviral cure of hepatitis C, suppression of hepatitis B, weight loss and diabetes control
- Beta-blockers or banding to prevent bleeding from oesophageal varices
- Salt restriction and diuretics for fluid retention, with drainage for tense ascites
- Lactulose and rifaximin to prevent confusion
- Liver transplantation, which is the definitive treatment for decompensated disease
Living with it day to day
Nutrition is underestimated: people with cirrhosis need plenty of protein and a late-evening snack. Avoid raw shellfish, be careful with paracetamol dose, and avoid anti-inflammatory painkillers entirely.
When to seek medical help
Go to hospital for vomiting blood or black stools, increasing confusion, fever with abdominal pain, or rapidly swelling abdomen.
