“…Loss of body weight is a common sequela of gastrectomy; however, there has been no consensual explanation for the impact of gastrectomy on nutritional status (Miyoshi et al, 2001;Katai et al, 2003). Complex mechanisms seem to be involved, including abnormal transit and diarrhea (Takase et al, 2003), dumping syndrome (Schölmerich, 2004), reduced food intake because of early satiety and loss of appetite (Liedman et al, 2001;Bergh et al, 2003), and alteration of endocrine status, such as reduced ghrelin release (Date et al, 2000;Hosoda et al, 2006) or increased satiety mediators such as cholecystokinin (Bergh et al, 2003), PYY 3À36 (Stratis et al, 2006;Borg et al, 2007) or glucagon-like peptide-1 (Borg et al, 2007).…”
