[Malnutrition in the elderly].

Malnutrition, which occurs in 27.4% of all elderly persons, is a great burden to those affected and for the health services. There are multiple causes for malnutrition, such as loss of appetite, poorly balanced diet, dementia, dysphagia chewing problems, as well as gastrointestinal disorders. Presence of weight loss and/or anorexia point towards malnutrition. A prerequisite for properly targeted nutritional intervention is to distinguish between sarcopenia and kachexia. In addition the "Mini Nutritional Assessment" (MNA (®)) questionnaire can be used quickly and reliably for diagnose malnutrition as recommended by the European Society for Clinical Nutrition and Metabolism. Treatment should be based on an individually designed nutritional regime, which incorporates eating habits and functional impairment of the patient.
