Cirrhosis of Liver

Cirrhosis of the liver is a chronic and progressive liver disease characterized by the replacement of healthy liver tissue with scar tissue (fibrosis), which impairs liver function. Cirrhosis can be caused by various factors, with chronic liver injury and inflammation being the common underlying mechanisms. Some of the main causes of cirrhosis include:

  • Chronic alcohol consumption: Alcohol-related liver disease is one of the leading causes of cirrhosis worldwide. Chronic and excessive alcohol consumption can lead to inflammation, fatty liver disease (steatosis), and ultimately, liver fibrosis and cirrhosis.
  • Chronic viral hepatitis: Chronic infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) can lead to ongoing liver inflammation and damage, eventually progressing to cirrhosis if left untreated.
  • Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH): NAFLD refers to the accumulation of fat in the liver in individuals who do not consume excessive amounts of alcohol. When NAFLD progresses to inflammation and liver cell injury, it is known as NASH. NASH can lead to fibrosis and cirrhosis over time, particularly in individuals with additional risk factors such as obesity, diabetes, or metabolic syndrome.
  • Chronic autoimmune liver diseases: Autoimmune liver diseases, such as autoimmune hepatitis, primary biliary cholangitis (formerly known as primary biliary cirrhosis), and primary sclerosing cholangitis, involve the immune system mistakenly attacking the liver, leading to chronic inflammation and liver damage that can progress to cirrhosis.
  • Genetic disorders: Inherited genetic disorders that affect liver function or metabolism can lead to cirrhosis. Examples include hereditary hemochromatosis (excessive iron accumulation in the liver), Wilson’s disease (copper accumulation), and alpha-1 antitrypsin deficiency.
  • Chronic biliary obstruction: Conditions that obstruct the bile ducts and impair bile flow can lead to bile buildup in the liver, inflammation, and bile duct damage, ultimately resulting in cirrhosis. Examples include primary sclerosing cholangitis, biliary atresia (a congenital defect), and recurrent biliary obstruction (e.g., from gallstones).
  • Toxic liver injury: Exposure to certain toxins, chemicals, medications, or environmental pollutants over time can damage liver cells and lead to cirrhosis. Examples include prolonged exposure to industrial chemicals, certain medications (e.g., methotrexate, isoniazid), and ingestion of toxins such as aflatoxins (produced by molds).
  • Chronic heart failure: Long-standing congestive heart failure can lead to liver congestion and chronic liver injury, eventually resulting in a form of cirrhosis known as cardiac cirrhosis.

It’s important to note that cirrhosis is often asymptomatic in the early stages and may progress silently until complications arise. Treatment aims to manage underlying causes, prevent disease progression, and manage complications. However, in advanced stages, liver transplantation may be necessary for survival. Therefore, early detection and intervention are crucial in managing cirrhosis and improving outcomes.
