Studying Effects of Different Low Blood Sugar Levels on Vascular Health in Healthy Adults Aged 18-55

What this Trial Is About

Researchers are investigating how different levels of low blood sugar hypoglycemia affect blood vessel function and blood clotting processes in healthy adults. This study aims to understand the biological effects of mild to moderate hypoglycemia on the vascular system, as previous research has linked severe hypoglycemia to heart problems but has not explained the underlying mechanisms. The research focuses on healthy individuals to provide clear insights into these effects. Participants will undergo a procedure called a glucose clamp, where blood sugar is carefully controlled and maintained at one of four target levels 90, 70, 60, or 50 mgdl for 90 minutes. Each participant will be randomly assigned to one of these four groups to compare how different degrees of hypoglycemia influence vascular biology. The glucose clamp is a device-based intervention to keep blood sugar steady during the study period. During the study, researchers will measure blood vessel function using flow-mediated vasodilation of the brachial artery before and after the glucose clamp. Additional evaluations include monitoring inflammation and blood clotting factors related to hypoglycemia. The study includes healthy volunteers aged 18 to 55, with assessments of blood tests and physical health to ensure safety. The total participation involves these measurements to understand the bodys response to controlled low blood sugar levels.
