Liver cirrhosis is a chronic disease that represents a major public health problem in the world. It can be the result of various causes, such as obesity, NASH, heavy alcohol consumption, hepatitis B or C infection, autoimmune diseases, and iron or copper intoxication. Cirrhosis develops after a long period of inflammation that results in the replacement of healthy liver parenchyma by fibrous tissue and regenerative nodules, leading to portal hypertension. The disease develops from an asymptomatic phase, thet is compensated cirrhosis, to a symptomatic phase, i.e. decompensated cirrhosis, whose complications often result in hospitalization, impaired quality of life and high mortality. Diagnostic procedures, history and physical examination, laboratory and radiological tests are of crucial importance because they confirm the diagnosis, reveal the etiology, assess the functional state of the liver and detect complications. Treatment for cirrhosis of the liver focuses on treating the cause and complications. It is carried out using a number of non-pharmacological, pharmacological and therapeutic procedures, and in some cases liver transplantation may be necessary. Cirrhosis has many clinical symptoms, pathophysiological disorders and complications, the most common of which are ascites and edema, gastrointestinal bleeding, hepatic encephalopathy and spontaneous bacterial peritonitis.
