Effects of glucagon on insulin secretion and glucose metabolism in people without diabetes

Effect of Glucagon on Fasting Insulin Secretion and Glucose Metabolism in Subjects Without Type 2 Diabetes

Not applicable Interventional Mayo Clinic · NCT06424106

This study is testing how glucagon affects insulin and blood sugar levels in people who have normal or slightly high fasting glucose to better understand how to manage blood sugar.

What this trial studies

This study investigates how glucagon and insulin interact to regulate fasting glucose levels in individuals with normal or impaired fasting glucose. It aims to understand the mechanisms behind fasting hyperglycemia, which is a significant contributor to complications in type 2 diabetes. The research will involve administering glucagon and glucose to assess their effects on insulin secretion and glucose metabolism. By exploring these interactions, the study seeks to fill gaps in knowledge regarding fasting glucose regulation in health and prediabetes.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with normal or impaired fasting glucose and normal or impaired glucose tolerance.

Not a fit: Patients with an HbA1c less than 6.5% or those currently using glucose-lowering agents will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of fasting glucose levels, potentially reducing the risk of developing type 2 diabetes.

How similar studies have performed: While the specific interactions being studied may not have been extensively tested, the investigation into glucagon's role in glucose metabolism is a relevant area of research with potential for significant findings.
