Abstract | BACKGROUND: METHODS: RESULTS: The body weight decreased markedly (P <.001) after either procedure (percentage of weight loss 16.4% ± 1.3%, 24.8% ± 1.7%, and 34.5% ± 2.7% after LRYGB and 13.1% ± 1.1%, 20.7% ± 1.5%, and 27.9% ± 2.6% after LSG at 2, 6, and 12 mo, respectively). The Homeostasis Model Assessment Index declined from 8.0 ± 1.5 preoperatively to 2.9 ± .2 at 12 months after LRYGB and from 7.5 ± 1.7 preoperatively to 3.3 ± .3 at 12 months after LSG. The lipid profiles were normalized. The concentrations of circulating leptin levels decreased by almost 50% as early as 1 week postoperatively and continued to decrease until 12 months postoperatively. Adiponectin increased progressively. The fibroblast growth factor-21 levels did not change over time. No difference was found between the LRYGB and LSG groups. CONCLUSION:
