Malnutrition and sarcopenia are common complications in patients with malignant diseases of the gastrointestinal tract. During chemotherapy there is a high risk of further impairment of nutritional status due to anorexia, nausea, emesis and other gastrointestinal conditions that adversely impact food assimilation or absorption.
