Liver cirrhosis is a late-stage liver disease characterized by the replacement of healthy liver tissue with scar tissue. This scarring impairs the liver's ability to function properly, affecting processes like detoxification, protein synthesis, and digestion. Common causes include chronic alcohol abuse, viral infections like hepatitis, and fatty liver disease. Symptoms of liver cirrhosis may include fatigue, jaundice (yellowing of the skin and eyes), and swelling in the legs and abdomen. As the disease progresses, complications can arise, such as liver failure and increased risk of liver cancer. Early diagnosis and management are crucial for improving outcomes.
