Recently, vaspin was identified as a novel adipokine with insulin-sensitizing effects that might be implicated in endogenous glucose regulation. Our objective was to evaluate the impact of acute weight loss and metabolic changes on serum vaspin concentrations in morbidly obese subjects following laparoscopic Roux-en-Y gastric bypass (RYGB) surgery.
