The study sample will comprise of 170 adults with biopsy proven cirrhosis. A detailed medical and nutritional assessment will be implemented at baseline. For patients that will receive an intervention aiming at the cause of cirrhosis (e.g. antivirus therapy for HCV or HBV) the baseline assessment will take place before the beginning of the therapy and will be repeated three months after the completion of the medical intervention to explore the impact of the intervention on nutritional status. Data regarding the survival of all the patients will be collected one year after the baseline assessment.
