Recently the medical community has had a difficult time identifying the role that ghrelin, a hormone released from the stomach and hypothalamus, has in weight loss following bariatic surgery. Ghrelin has been shown to be a potent appetite stimulator and may play a role in weight regulation following bariatic surgery. The goal of the experiment was to address the discrepancies arising from conflicting experimental evidence on whether or not plasma ghrelin levels play a role in weight regulation following significant weight loss after laparoscopic Roux-en-Y gastric bypass (LRYGBP). Furthermore, the researchers took into consideration two other hormones: insulin and adiponectin, which have been shown to help regulate ghrelin levels in the body.
