Prospective study of gut hormone and metabolic changes after adjustable gastric banding and Roux-en-Y gastric bypass
Open accessAbstract
Objective:The objective of this study was to quantify hormones that regulate energy and glucose homeostasis to establish possible mechanisms for the greater efficacy of Roux-en-Y gastric bypass (RYGB) compared with laparoscopic adjustable gastric banding (LAGB) in achieving weight loss and improved insulin sensitivity.Design:Longitudinal study of patients undergoing LAGB (n=15) and RYGB (n=28) who were studied before surgery and at 2, 12, 26 and 52 weeks afterwards.Measurements:Fasting blood samples were drawn at each visit. Postprandial blood samples were also obtained before surgery and at 26 and 52 weeks. Samples were assayed for peptide YY (PYY), ghrelin, glucagon-like peptide-1 (GLP-1), glucose, insulin, leptin, thyrotropic hormone, free T4 and free T3.Results:At 1 year there was greater weight loss in RYGB compared with LAGB patients (30 vs 15%), but final body mass index was similar (34 vs 33 kg m−2). At week 52, area under the curve (AUC) for PYY in RYGB subjects was greater than LAGB (P<0.01). GLP-1 levels at 30 min after meal were threefold greater after RYGB compared with LAGB (P<0.001). Conversely, ghrelin AUC increased after LAGB at week 52 (P<0.05) but tended to decrease after RYGB. Fasting glucose, insulin, and leptin and homeostasis model of assessment (HOMA-IR) decreased in both groups over time but were significantly lower at week 52 after RYGB compared with LAGB. The change in leptin correlated significantly with weight loss in LAGB (r=0.86) and RYGB (r=0.77), however, HOMA-IR correlated significantly with weight loss only in LAGB (r=0.78), and not RYGB (r=0.15). There was a significant decrease in free T3 (P<0.01) after RYGB.Conclusions:Differences in levels of gut hormones may play a role in promoting greater weight loss and insulin sensitivity after RYGB compared with LAGB, however, weight loss may be limited by decreases in free T3 and leptin.

The non-randomized LAGB and RYGB groups are comparable enough that between-group differences in outcomes can be attributed to the procedures.
“The choice of bariatric procedure was based on the preference of surgeon and patient.”
“body weight (112 ± 5 vs 128 ± 5 kg; P = 0.056) and BMI (41 ± 1 vs 48 ± 1 kg/m2; P < 0.001) were less in LAGB compared with RYGB.”
The paper relies on this without support.
Most subjects had not reached their nadir weight at 1 year.
“Since most of our subjects were unlikely to have achieved their nadir weight at 1 year, it may be too early to detect significant correlations between levels of L cell peptides and ultimate response to surgery.”

“Although these associations do not prove causality, inhibition of gut hormone release by administration of somatostatin increased appetite and food intake in bypass but not in band subjects, suggesting that gut hormones are more likely to mediate reduced appetite and food intake after RYGB (24).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
