Hepatic Disease and Cirrhosis

Cirrhosis is the advanced, scarring stage of chronic liver disease, in which progressive fibrosis and the formation of regenerative nodules distort the liver's architecture and impair its function. It is the common endpoint of conditions such as chronic viral hepatitis, alcohol-related liver disease, and metabolic (fatty) liver disease. As cirrhosis advances it can decompensate, producing ascites, variceal bleeding, hepatic encephalopathy, and jaundice, which makes it a demanding and high-acuity topic in medical-surgical nursing.

Definition

Cirrhosis is a late stage of chronic liver disease characterised by diffuse fibrosis and the replacement of normal liver tissue with regenerative nodules, leading to portal hypertension and progressive loss of hepatic synthetic and metabolic function.

Scope

The entry covers the definitions, mechanisms, presentation, and management context of cirrhosis and chronic liver disease as a reference subject for nursing. It addresses the progression from compensated to decompensated disease, the major complications of portal hypertension and liver failure, and the multidisciplinary and nutritional management framework, without giving individualised drug dosing or treatment instructions.

Core questions

• How does chronic liver injury progress to fibrosis, cirrhosis, and portal hypertension?
• How does cirrhosis differ in its compensated and decompensated stages?
• What are the major complications of decompensated cirrhosis and how are they recognised?
• Why is nutritional status a central concern in chronic liver disease?

Key concepts

• Hepatic fibrosis and regenerative nodules
• Compensated versus decompensated cirrhosis
• Portal hypertension
• Ascites
• Oesophageal and gastric varices
• Hepatic encephalopathy
• Malnutrition and sarcopenia in liver disease

Mechanisms

Persistent liver injury—from viral hepatitis, alcohol, metabolic dysfunction, or other causes—triggers chronic inflammation and activation of hepatic stellate cells, which deposit excess extracellular matrix. Over time this fibrosis and the formation of regenerative nodules distort the hepatic vasculature, increasing resistance to portal blood flow and producing portal hypertension; the resulting splanchnic vasodilation and circulatory changes underlie ascites and variceal formation (Angeli et al., 2018; Garcia-Tsao et al., 2017). As functioning liver mass declines, synthetic, detoxifying, and metabolic functions fail, and accumulation of nitrogenous substances contributes to hepatic encephalopathy. Impaired metabolism and reduced intake also drive the malnutrition and muscle loss common in advanced disease (Merli et al., 2019).

Clinical relevance

Decompensated cirrhosis is associated with high morbidity and mortality and frequently requires hospital and critical care, with complications such as variceal haemorrhage, refractory ascites, spontaneous bacterial peritonitis, and hepatic encephalopathy. Recognising the transition to decompensation and its complications supports timely, coordinated care; this entry describes the disease for reference and is not a basis for individual diagnostic or treatment decisions.

Epidemiology

Cirrhosis is a leading cause of liver-related death worldwide, and its principal drivers—chronic viral hepatitis, alcohol-related liver disease, and metabolic (formerly non-alcoholic) fatty liver disease—vary in relative importance across regions. International guidelines from the European Association for the Study of the Liver and the American Association for the Study of Liver Diseases describe management of its complications across the disease course (Angeli et al., 2018; Garcia-Tsao et al., 2017).

Frequently asked questions

What is the difference between compensated and decompensated cirrhosis?

In compensated cirrhosis the liver is scarred but still maintains adequate function and the person may have few symptoms, whereas decompensated cirrhosis is marked by major complications such as ascites, variceal bleeding, or hepatic encephalopathy and carries a worse prognosis.

Why are people with cirrhosis at risk of malnutrition?

Advanced liver disease impairs the metabolism and storage of nutrients, often reduces appetite and intake, and increases muscle breakdown, so malnutrition and loss of muscle mass are common and are an important focus of nutritional assessment.
