NCT ID NCT07581860
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 2 times
Summary
This study looks at how beta-cells (which make insulin) respond to growth hormone in people with prediabetes. Researchers will measure insulin release in 10 adults with impaired fasting glucose or impaired glucose tolerance. The goal is to better understand what raises the risk of developing type 2 diabetes.
