Ernährung und chronisch entzündliche Darmerkrankungen - ein Konsensus der Arbeitsgruppe chronisch entzündliche Darm- erkrankungen der Österreichischen Gesellschaft für Gastroenterolo- gie und Hepatologie (Austrian Guidelines for nutrition in IBD) Nutrition and IBD-Consensus of the Austrian Working Group of IBD (Inflamma- tory Bowel Diseases) of the ÖGGH

This is a consensus of the Austrian working group of IBD (inflammatory bowel diseases) of the OGGH on nutrition in IBD. Malnutrition should be assessed in case of IBD (in 20-70% of Crohn's patients) and weight loss(>5% within 3 months) or nutritional deficiencies or after extensive bow- el resection and afterwards also treated. Malnu- trition should be treated with medical therapy of IBD and also adequate - as far as possible - with oral nutritional therapy particularly because of reduced life quality, risk of opportunistic infec- tions, osteopenia/osteoporosis, longer hospitali- sations and higher mortality. Iron homeostasis, serum levels of Vitamin B12- and folic acid, 25- hydroxyvitamin D and zinc should be checked. Therapy with enteral liquid diets is only indicated as therapy of first choice in children and adoles- cents, but only in rare situations in adults with IBD. There is - up to now - no proven oral diet for maintenance of remission in IBD. Probiotics as E. coli Nissle could be used as alternative to me- salazine for maintenance of remission in patients with ulcerative colitis. A specific dietary counsel- ling is mandatory in patients with ileostoma or short bowel syndrome. Malnutrition of short bowel patients is particularly dependent on the function and length of the remaining bowel, therefore the most effective medical therapy should be administered.
