Gut Hormones Rise Progressively After Gastric Bypass — Explaining Long-Term Weight Loss Success

CohortModerate evidence
The takeaway

GLP-1, PYY, and other gut satiety hormones progressively increased over months after Roux-en-Y gastric bypass, suggesting gut adaptation and providing the hormonal explanation for the surgery's sustained appetite suppression.

Key finding

GLP-1 and PYY3-36 progressively increased over months post-RYGB, with the rise correlating with reduced appetite and sustained weight loss — gut hormo

What the researchers found

GLP-1 and PYY3-36 progressively increased over months post-RYGB, with the rise correlating with reduced appetite and sustained weight loss — gut hormonal adaptation (not just restriction) explains bariatric surgery's long-term success.

Why it matters

Relevant for glp-1, weight-loss, gut-healing.

How the study worked
