alcoholic liver cirrhosis

Cirrhosis

Cirrhosis, also known as liver cirrhosis, hepatic cirrhosis, chronic liver failure, chronic hepatic failure, and end-stage liver disease, is a chronic condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue (fibrosis) and regenerative nodules as a result of chronic liver disease. Damage to the liver leads to repair of liver tissue and subsequent formation of scar tissue. Over time, scar tissue and nodules of regenerating hepatocytes can replace the parenchyma, causing increased resistance to blood flow in the liver's capillaries—the hepatic sinusoids—and consequently portal hypertension, as well as impairment in other aspects of liver function. The disease typically develops slowly over months or years. Stages include compensated cirrhosis and decompensated cirrhosis. Early symptoms may include tiredness, weakness, loss of appetite, unexplained weight loss, nausea and vomiting, and discomfort in the right upper quadrant of the abdomen. As the disease worsens, symptoms may include itchiness, swelling in the lower legs, fluid build-up in the abdomen, jaundice, bruising easily, and the development of spider-like blood vessels in the skin. The fluid build-up in the abdomen may develop into spontaneous infections. More serious complications include hepatic encephalopathy, bleeding from dilated veins in the esophagus, stomach, or intestines, and liver cancer. Cirrhosis is most commonly caused by medical conditions including alcohol-related liver disease, metabolic dysfunction–associated steatohepatitis (MASH – the progressive...
