Some liver diseases can be prevented (for instance by immunization or by avoiding toxic substances), and in others an early diagnosis is important for an effective treatment. An advanced chronic liver disease often becomes obvious by pronounced tiredness and weakness, by accumulation of fluid in the peritoneal cavity ("ascites") by massive hemorrhage from oesophageal varices or from mental disturbances up to coma. However, an early diagnosis can be difficult because many liver diseases develop in the absence of unambiguous symptoms. Even people who feel completely healthy may suffer from liver disease. Through our special knowledge and the application of the most up-to-date techniques, we are especially qualified to make a balanced assessment and to decide on the appropriate (and sometimes life-saving) treatment at the earliest possible time point.
