Outcome Measures

Primary Outcomes (2)

  • Change in Postprandial Glucose Levels After Mixed Meal Test

    Glucose levels were measured in study participants while fasting and periodically over 3 hours after drinking a 200 kcal mixed meal test, before and after intervention (Sitagliptin or Placebo).

    Baseline and ~4 weeks

  • Change in Area Under the Curve (AUC) Glucose Levels After Mixed Meal Test

    Glucose levels were measured in study participants while fasting and periodically over 3 hours after drinking a 200 kcal mixed meal test, before and after intervention (Sitagliptin or Placebo). AUC was measured by trapezoidal method.

    Baseline and ~4 weeks

Secondary Outcomes (3)

  • Effect of Sitagliptin vs Placebo on Satiety in Patients With Type 2 Diabetes After Gastric Bypass Surgery
