The Relationship Between Sleep and Glucose Tolerance in Prediabetes: the Role of GLP-1 in Short Sleepers

Hypothesis

1. Prediabetes patients who have insufficient sleep will have worse glucose tolerance than those with normal sleep duration. 2. Prediabetes patients with short sleep will have a delayed or reduced GLP-1 response to a standardized meal
