Medical treatment of patients with liver cirrhosis consists mainly of symptomatic therapy of associated complications. Apart from the classical complications of cirrhosis, e. g. ascites, portal hypertension or hepatic encephalopathy, other frequent complications are neglected in everyday medicine. The incidence of metabolic disturbances seems to be similar to the prevalence of classical complications of liver cirrhosis, such as portal hypertension or ascites. Osteoporosis is an important manifestation of hepatic osteopathy, especially in chronic cholestatic diseases and in candidates for liver transplantation, which necessitates timely adequate diagnostic test (e. g. osteodensitometry) and treatment (pre-emptive and causal). Malnutrition, especially when related to protein- and energy supply, is very common in patients with liver cirrhosis and has prognostic significance regarding mortality and complication rates. A sufficient daily energy and protein supply should be ensured, one which is higher than that for the normal population. Additional substitution of vitamins and trace elements is indicated when symptoms of deficiency became apparent.
