What this trial studies

This project investigates the physiological effects of GIP, GLP-1, and GLP-2 hormone infusions in individuals carrying genetic variants affecting these receptors. Participants will undergo a series of randomized experimental days involving glucose tolerance tests and hormone infusions to assess their metabolic responses. The study aims to understand how these hormones function in individuals with specific genetic mutations, providing insights into their role in metabolism. Additionally, participants will undergo DXA scans and arginine tests to gather comprehensive data on their physiological status.

Who should consider this trial

Good fit: Ideal candidates are individuals with a BMI between 19-35 kg/m2 who carry mutations in the GIP, GLP-1, or GLP-2 receptors.

Not a fit: Patients with liver disease, decreased kidney function, or those on medications that cannot be paused may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment options for metabolic disorders related to incretin hormones.

How similar studies have performed: While the specific approach of this study is novel, similar studies investigating the effects of incretin hormones have shown promising results in understanding metabolic functions.
