Long-Term Modulation of Appetitive Hormones and Sweet Cravings After Adjustable Gastric Banding and Roux-en-Y Gastric Bypass

Roux-en-Y gastric bypass (RYGB) produces greater weight loss compared with a purely restrictive procedure such as laparoscopic adjustable gastric banding (LAGB).The objective of this study was to quantify changes in hormones that regulate energy homeostasis and appetitive sensations before and after LAGB (n = 18) and RYGB (n = 38) in order to better understand the mechanisms underlying the greater weight loss after RYGB.A standardized test meal...
