Growth Hormone Resistance of Beta-cells A
Recruiting · NCT06571487 · Observational (researchers observe without assigning treatment)
View the official record on ClinicalTrials.gov →What this trial is about
The purpose of the research study is to better understand how beta-cells (cells in the pancreas that make insulin and help regulate blood sugar) respond to growth hormone in people with a personal history of gestational diabetes (high blood sugar in pregnancy) at the University of Missouri. The aim of the study is to advance understanding of how growth hormone affects beta-cells and risk factors for developing gestational diabetes.
