Bariatric surgery dramatically shifted gut hormone profiles toward an anorectic state — elevated GLP-1, PYY, oxyntomodulin with suppressed ghrelin — explaining both the weight loss and metabolic improvements post-surgery.

What the researchers found
Bariatric surgery produced comprehensive gut hormone profile transformation: elevated GLP-1, PYY3-36, and oxyntomodulin with suppressed ghrelin, creating an anorectic hormonal milieu that facilitates weight loss and improves glucose metabolism beyond mechanical restriction.
