1. A and B. Ghrelin secretion after bariatric surgery
A and B. Ghrelin secretion after bariatric surgery. Some investigators have suggested that ghrelin secretion is dramatically decreased after gastric bypass. Other groups have shown statistically insignificant changes in ghrelin levels after gastric bypass, (RYGBP) but significant decreases after sleeve gastrectomy (SG). A: green = gastric bypass; blue = obese controls; red = normal weight controls; B: blue = fasting; pink = postprandial. B. Top = RYGBP; B bottom = SG.
