[Nutrition and fluid management in palliative medicine: do food and drink keep body and soul together?].

Induction, implementation and continuation of an invasive nutrition or fluid administration in patients with advanced, life-limiting illnesses is an often controversial but also very emotionally discussed topic. This article summarizes the current state of knowledge based mainly on the European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines and is intended as a simple guide for clinical practice. In the early phase of disease the induction of an invasive food and fluid administration may be indicated in order to prevent undernutrition and cachexia, to enhance compliance with anti-tumor treatment, to control some adverse effects of anti-tumor therapy and to improve the quality of life. If oral or enteral feeding is possible this should be preferred. Patients in the final stage of a disease rarely suffer from hunger or thirst. In this phase of the disease other things, such as monitoring of patients and relatives play a much more important role.
