Use of a Hyperinsulinemic-hypyglycemic Clamp to Study Hypoglycemia: a Method Development Study

Subjects will arrive at the inpatient unit in the morning after at least a 10 hour overnight fast. Upon arrival to PBRC, participants will be admitted to the inpatient unit. Following measurement of weight, vitals, and pregnancy test (women only), the 4-hour hypoglycemic clamp procedure (30 minute baseline, 120 minute insulin infusion, and 90 minute recovery) will be performed. Upon completion of the clamp procedure, participants will be provided lunch (Standard American Diet). Following lunch, the CGM sensor will be removed and pending a stable blood glucose level in the normal range, the participant will be discharged from the inpatient unit. This completes the study.
