Cirrhosis

Cirrhosis is a serious liver condition that develops when healthy liver tissue is replaced by scar tissue, gradually reducing the liver’s ability to filter toxins, produce proteins, and regulate metabolism. It is a major cause of abnormal liver tests, low albumin levels, and unexplained fatigue—and is often first detected through routine blood work before symptoms appear.

As scar tissue builds, it disrupts normal liver architecture and blood circulation, impairing overall liver function. This process typically develops over years of chronic liver injury and represents the final stage of many forms of liver disease.

Disease Progression

Cirrhosis progresses through two main stages:

• Compensated cirrhosis:
  The liver is significantly scarred but still able to perform most of its functions. Many individuals have no symptoms, and the condition is often identified through abnormal lab markers.
• Decompensated cirrhosis:
  Liver function declines, leading to complications such as fluid buildup, bleeding, and cognitive changes. This stage carries a higher risk of hospitalization and mortality.

Understanding this progression is critical, as early detection can significantly slow disease advancement.

What Causes Cirrhosis?

Cirrhosis develops as a result of long-term liver damage. Common causes include:

• Most common causes:
  • Chronic viral hepatitis (hepatitis B and C)
  • Alcohol-related liver disease
  • Nonalcoholic fatty liver disease (NAFLD/NASH)
• Other causes:
  • Autoimmune hepatitis
  • Genetic conditions (e.g., hemochromatosis, Wilson disease)
  • Bile duct diseases (e.g., primary biliary cholangitis)
  • Long-term exposure to medications or toxins

Key Biomarkers & Tests

Cirrhosis is frequently identified and monitored through lab testing:

• Liver enzymes (AST, ALT, ALP, GGT)
• Bilirubin
• Serum albumin
• Prothrombin time (INR)
• Platelet count
• Creatinine

Imaging tests such as ultrasound or elastography help assess liver stiffness and structure.

As cirrhosis progresses, albumin levels typically decrease, while bilirubin and INR increase, reflecting declining liver function. A low platelet count is often one of the earliest warning signs due to increased pressure in the liver’s blood vessels.

Signs and Symptoms of Liver Cirrhosis

Cirrhosis often begins silently. As the disease progresses, symptoms may include:

• Fatigue and weakness
• Loss of appetite and unintentional weight loss
• Nausea
• Easy bruising or bleeding
• Jaundice (yellowing of the skin and eyes)
• Fluid buildup in the abdomen (ascites) or legs
• Confusion and memory problems caused by toxic buildup

Complications

Advanced cirrhosis can lead to serious complications:

• Portal hypertension (increased pressure in liver blood vessels)
• Ascites (abdominal fluid accumulation)
• Variceal bleeding (bleeding from enlarged veins)
• Infections due to weakened immune function
• Kidney dysfunction (hepatorenal syndrome)
• Liver cancer (hepatocellular carcinoma)

Many of these complications can be detected early through regular lab monitoring—falling albumin, rising bilirubin, worsening INR, or declining platelet counts are often the first signs that liver disease is progressing.

Treatment & Management

Cirrhosis cannot usually be reversed, but its progression can often be slowed with early intervention and proper management.

• Address underlying causes such as hepatitis, alcohol use, or metabolic disease
• Medications to manage complications (e.g., diuretics, beta blockers, lactulose)
• Nutritional and lifestyle changes
• Regular monitoring with lab tests and imaging
• Liver transplantation in advanced cases

Many patients remain stable for years, especially when cirrhosis is detected early. However, as liver disease progresses, the risk of complications increases—making ongoing lab monitoring essential for detecting changes early and guiding treatment decisions.
