Outcome Measures

Primary Outcomes (1)

  • Beta Cell Sensitivity (BCS)

    Oral glucose tolerance test (OGTT) will be used to calculate BCS Graded glucose infusion with arginine (GGI) will be used to calculate BCS

    at 2 years post GBP surgery

Secondary Outcomes (3)

  • Insulin Secretion Rate (ISR) after OGTT

    2 years post GBP surgery

  • Insulin Secretion Rate (ISR) after GGI

    2 years post GBP surgery

  • Maximal Beta Cell Function

    2 years post GBP surgery

Study Arms (1)

Exendin9

EXPERIMENTAL

Longitudinal study of insulin secretion and sensitivity in patients with type 2 diabetes before and after gastric bypass surgery.

Drug: Exendin9

Interventions

Dosed at 600 pmol/kg/min for 210 minutes.

Also known as: Exendin(9-39)
