Abstrakt:	Introduction: Weight loss after bariatric surgery is attributed, at least in part, to the altered gastrointestinal (GI) hormone secretion, which is thought to be responsible for a number of beneficial metabolic effects. Material and Methods: We conducted a cross-sectional study. Twelve patients who underwent laparoscopic sleeve gastrectomy (SG) and 20 patients who underwent a variant of biliopancreatic diversion with Roux-en-Y gastric bypass and long limbs (BPD/RYGB-LL) were evaluated ≥ 7 years postoperatively. Ghrelin, glucagon-like peptide-1 (GLP-1), and peptide YY (PYY) secretion were compared between patients with successful weight loss maintenance (WM group) and patients with weight regain (WR group). Results: In both types of surgery, standard liquid mixed meal (SLMM) ingestion did not result in significant changes in fasting GI hormone levels. Fasting ghrelin levels did not differ between the WM group and the WR group in both types of surgery. In SG patients, SLMM ingestion elicited greater suppression of ghrelin levels in the WM group (p = 0.032). No difference in GLP-1 secretion was observed between the 2 groups of patients in both types of surgery. When patients were examined, regardless of the type of bariatric surgery they had undergone, postprandial PYY levels were lower in the WM group (p < 0.05), while fasting and postprandial PYY levels were correlated positively with an increase in body mass index (BMI) in the evaluation (Spearman's rho ≥ 0.395, p < 0.03). Conclusions: Our data do not support the hypothesis that long-term weight regain after bariatric surgery is associated with an unfavourable GI hormone secretion pattern.
