Emergency surgery is associated with an increase in the risk of malnutrition in the elderly. Thirty to fifty percent of elderly persons admitted to in surgery are malnourished. In patients for which nutritional status is threatened by both the aging process and comorbidities, the surgical intervention represents an additional stress that will induce or worsen malnutrition. Nutritional care must no be delayed. First choice is the oral route, including protein and energy rich nutritional supplements, and must be a part of multidimensional perioperative care It is recommended to reach 30 to 40 kcal tot/kg/day and 1.2 to 1.5 g of proteins/kg/day. It is recommended to prescribe, during the stay in rehabilitation wards after surgery, oral nutritional supplements. This oral supplementation has been shown to be efficacious in malnourished elderly patients: there is weight gain, a lower risk for complications and a lower mortality rate. However, compliance may be reduced in elderly patients with low appetite, especially in case of dementia, or early medical complications. In order to prevent other falls and fractures, it is recommended to look for vitamin D deficiency and to prescribe vitamin D 800–1200 UI/day.
