[Gastrointestinal metabolic surgery improves salt-sensitive hypertension via GLP-1-mediated inhibition of the RAS/NHE3 axis].

Article C Peer reviewed Observational

Key takeaways

In 57 people who had gastric bypass, a weight-loss surgery, those with high blood pressure were studied before and after the operation. The surgery lowered blood pressure that rises with salt. Animal tests pointed to a gut hormone (GLP-1) that blocks a salt-handling pathway in the kidney. The human part shows a link, not proof, and it did not measure long-term kidney health.
