Scientists once had high hopes that inhibiting a hormone named ghrelin would be the key to preventing obesity. Ghrelin didn’t turn out to be a weight loss panacea. But now, the discovery of the first molecule naturally made by the body that blocks ghrelin’s effects may open up new avenues for treating other conditions, including diabetes and anorexia. The finding may also explain some of the benefits of bariatric surgery, which shrinks or reroutes the stomach to control weight.
