ELI5: What is cirrhosis of the liver?

Cirrhosis is long-term scarring of the liver—repeated damage turns a soft, healthy “filter” into stiff scar tissue so it can’t clean toxins, make important proteins and bile, or control body fluids properly. It often stems from alcohol, hepatitis B/C, or fatty liver disease and can lead to swelling, confusion, bleeding, and liver cancer; there are several factors to consider—see below for full details on causes, symptoms, diagnosis, stages, treatments, and when to seek care.

Explanation

What Is Cirrhosis of the Liver?

Cirrhosis of the liver is like a chronic injury to a sponge. Normally, your liver is soft and smooth, filtering toxins, helping you digest food, and storing energy. With cirrhosis, repeated damage causes the liver to develop thick bands of scar tissue. Over time, this scar tissue replaces healthy liver cells, making the organ stiff and unable to work properly.

Key points:

  • “Cirrhosis” literally means scarring of the liver.
  • It develops slowly—often over years.
  • Scar tissue blocks blood flow and stops healthy cells from regenerating.
  • The liver’s vital jobs—filtering toxins, producing proteins, and making bile—become harder or impossible.

Why Does Cirrhosis Happen?

Cirrhosis of the liver can result from many causes. The most common include:

• Chronic alcohol use
• Long-term viral hepatitis (especially hepatitis B or C)
• Non-alcoholic fatty liver disease (NAFLD), often linked to obesity or diabetes
• Autoimmune liver diseases (the body’s immune system attacks the liver)
• Genetic conditions (e.g., Wilson’s disease, hemochromatosis)
• Certain medications or toxins

Repeated injury from these conditions triggers inflammation. Inflammation is the body’s attempt to heal, but if it goes on too long, it leads to scar tissue formation.

How Does Cirrhosis Affect the Body?

When your liver becomes scarred:

  1. Blood flow slows down.

    • High pressure builds in vessels leading to the liver (portal hypertension).
    • This can cause fluid buildup in the abdomen (ascites) and swollen veins in the esophagus (varices).
  2. Toxin clearance drops.

    • Ammonia and other waste products build up, possibly affecting brain function (hepatic encephalopathy).
  3. Protein and hormone production falls.

    • You may bruise easily (due to low clotting factors).
    • Fluid regulation is affected (low albumin can worsen swelling).
  4. Bile production is reduced.

    • Fat digestion suffers, leading to vitamin deficiencies and itchy skin.
  5. Risk of liver cancer rises.

    • Damaged cells can turn cancerous (hepatocellular carcinoma).

Signs and Symptoms

Early cirrhosis can be silent. You might feel fine until the liver is severely scarred. Common symptoms include:

• Fatigue and weakness
• Loss of appetite and unintended weight loss
• Nausea or abdominal discomfort
• Jaundice (yellowing of skin and eyes)
• Itchy skin
• Swollen abdomen (ascites) and legs (edema)
• Easy bruising or bleeding
• Confusion, poor concentration, or sleep changes (hepatic encephalopathy)
• Dark urine or pale stools

If you experience any of these, don’t panic—but do pay attention. Consider doing a free, online symptom check for Liver Cirrhosis.

How Doctors Diagnose Cirrhosis of the Liver

According to the EASL-ALEH guidelines, doctors combine clinical exams with non-invasive tests and, if needed, a liver biopsy:

  1. Medical history and physical exam

    • Ask about alcohol use, viral hepatitis risk, family history.
    • Check for enlarged liver or spleen, fluid in the abdomen, or spider-like blood vessels on the skin.
  2. Blood tests

    • Liver enzymes (ALT, AST) show inflammation.
    • Platelet count, bilirubin, albumin, and clotting factors assess liver function.
  3. Imaging studies

    • Ultrasound elastography (FibroScan) measures liver stiffness without a needle.
    • MRI or CT scans can detect nodules, fluid, or varices.
  4. Endoscopy

    • A camera checks for varices in the esophagus or stomach, caused by portal hypertension.
  5. Liver biopsy (if needed)

    • A small tissue sample confirms the amount of scarring and helps identify the cause.

Stages and Prognosis

Cirrhosis progresses through stages:

  1. Compensated cirrhosis

    • Liver still functions fairly well.
    • Symptoms may be mild or absent.
  2. Decompensated cirrhosis

    • Serious complications appear (ascites, variceal bleeding, encephalopathy).
    • Quality of life often declines; hospitalizations may be required.

Prognosis depends on: • Cause and how early it’s detected
• Severity of scarring (assessed by MELD or Child-Pugh scores)
• Presence of complications

Early diagnosis and lifestyle changes can slow progression. In advanced cases, a liver transplant may be the only option.

Treatment and Management

There’s no “cure” for cirrhosis of the liver, but treatments can: • Prevent further damage
• Manage complications
• Improve quality of life

Main strategies:

  1. Address the cause

    • Stop drinking alcohol.
    • Treat viral hepatitis with antiviral medications.
    • Control diabetes, obesity, or high cholesterol for NAFLD.
    • Use immune-suppressing drugs for autoimmune liver disease.
  2. Manage complications

    • Diuretics help reduce fluid buildup.
    • Beta-blockers or banding procedures lower the risk of variceal bleeding.
    • Lactulose or rifaximin ease encephalopathy by reducing toxins.
  3. Monitor closely

    • Regular blood tests and imaging for liver cancer screening.
    • Vaccinations (hepatitis A and B, flu, pneumonia).
  4. Nutritional support

    • High-protein diet (unless encephalopathy is severe).
    • Vitamins (especially fat-soluble A, D, E, K).
    • Salt restriction if you have fluid retention.
  5. Consider liver transplant

    • For end­stage cirrhosis or complications not controlled by other treatments.
    • Requires thorough evaluation and lifelong follow-up.

Living With Cirrhosis of the Liver

Day-to-day steps can make a big difference:

• Avoid alcohol and toxins.
• Eat a balanced diet with enough protein and calories.
• Keep a healthy weight and exercise as advised by your doctor.
• Take prescribed medications consistently.
• Monitor for new symptoms and report them promptly.
• Attend all follow­up appointments and screening tests.

Building a support network—family, friends, or liver-disease support groups—can help with the emotional and practical challenges of living with cirrhosis.

When to Speak to a Doctor

Cirrhosis of the liver can be life­long and sometimes life­threatening. Speak to a doctor if you notice:

• Unexpected swelling in your belly or legs
• Increased confusion or sleepiness
• Vomiting blood or black, tarry stools
• Severe abdominal pain or difficulty breathing
• Yellowing of skin or eyes that worsens

Prompt medical attention can prevent complications from becoming emergencies.
