Summary

This trial aims to understand how the body regulates blood sugar levels when a person hasn't eaten (fasting state) in comparison to after a meal (postprandial state). The study will focus

Who is the study for?
This trial is for individuals with prediabetes, a condition where blood sugar levels are higher than normal but not high enough to be type 2 diabetes. Participants should have fasting hyperglycemia and be interested in how their body regulates glucose when they haven't eaten.
What is being tested?
The study is looking at the effects of insulin and insulin pulses on blood sugar levels during fasting. It involves administering saline (saltwater solution), intralipid (a fat emulsion), and heparin (a medication that prevents blood clots) to see how these affect glucose control.
What are the potential side effects?
Potential side effects may include discomfort at the injection site from saline, changes in blood lipid levels due to intralipid, and increased bleeding risk or bruising from heparin.
