What is the Difference Between Fibrosis and Cirrhosis?

🆚 Go to Comparative Table 🆚

Fibrosis and cirrhosis are both terms used to describe scarring in the liver, but they represent different stages and degrees of severity.

Fibrosis refers to any degree of scarring in the liver. It can be partially reversed if the cause is identified and addressed early enough. Fibrosis is classified into different stages:

  • F0: No fibrosis
  • F1: Mild fibrosis
  • F2: Moderate fibrosis
  • F3: Advanced fibrosis
  • F4: Cirrhosis

Cirrhosis is a late-stage disease where scarring (fibrosis) is severe and extensive. It is characterized by the replacement of healthy liver tissue with scar tissue, which hardens the liver and interferes with its functions. Cirrhosis is considered irreversible, and liver damage is often permanent at this stage, although sometimes treatment can restore some lost function.

Causes of chronic liver disease that can lead to cirrhosis include non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease, chronic hepatitis viruses (Hepatitis B and C), autoimmune liver diseases, biliary diseases such as PBC and PSC, and hemochromatosis.

In summary, fibrosis is any degree of scarring in the liver, while cirrhosis is a late-stage, severe, and extensive pattern of scarring with a higher chance of complications. Cirrhosis is considered irreversible, whereas fibrosis can be partially reversed if addressed early enough.

    Fibrosis and cirrhosis are both conditions related to scarring in the liver, but they differ in severity and consequences. Here is a table summarizing the differences between fibrosis and cirrhosis:

    Feature Fibrosis Cirrhosis
    Definition Fibrosis is the accumulation of scar tissue in the liver due to damage or injury. Cirrhosis is the most severe form of fibrosis, characterized by advanced scar tissue in the liver surrounding regenerative nodules.
    Severity Fibrosis can range from mild to severe, with the potential to improve or reverse if the underlying cause is addressed. Cirrhosis is the end-stage of liver fibrosis and causes complications such as portal hypertension and liver failure.
    Causes and Prevalence Fibrosis can be caused by various factors, including chronic inflammation, hemochromatosis, and viral hepatitis. Cirrhosis is caused by ongoing liver damage, leading to the development of scar tissue that distorts the liver's structure.
    Symptoms Mild or no symptoms in some cases, but may include jaundice, tiredness, and an enlarged abdomen. Symptoms include fatigue, nausea, vomiting, jaundice, and swollen abdomen.
    Complications Cirrhosis is a complication of liver fibrosis. Complications of cirrhosis include gastrointestinal tract bleeding, portal hypertension, thrombocytopenia, pulmonary hypertension, fluid buildup in the abdomen (ascites), encephalopathy, and liver failure.
    Treatment Treatment is supportive and may include adding vitamin supplements, ligation to halt bleeding from esophageal varices, and liver transplant in severe cases. Treatment involves correcting the underlying condition when possible, addressing complications, and managing symptoms.

    In summary, fibrosis is a buildup of scar tissue in the liver due to damage or injury, while cirrhosis is the most severe form of fibrosis with advanced scar tissue in the liver. Cirrhosis causes various complications and often requires more intensive treatment and management compared to fibrosis.
