Drug Information available for: Insulin

Arm Intervention/treatment
Active Comparator: PreOp, NutriciaNordica AB
PreOp: 50 kcal/100 mL in the form of maltodextrin and fructose. One bottle of 800 ml to be ingested at bedtime, and at midnight by the latest, and another bottle with 400 ml approximately 2 hours before surgery started.
Dietary Supplement: Experimental: PreOp, NutriciaNordica AB
Other Name: PreOp, serial number 27 62 95, NutriciaNordica AB

Placebo Comparator: Water
Water: One bottle of 800 ml to be ingested at bedtime, and at midnight by the latest, and another bottle with 400 ml approximately 2 hours before surgery started.
Dietary Supplement: Placebo Comparator: Water



Primary Outcome Measures :
  1. Change in Insulin Sensitivity [ Time Frame: Morning before surgery and up to two days after surgery ]
    Insulin sensitivity is measured by euglycemic hyperinsulinemic clamp


Secondary Outcome Measures :
  1. Change in Beta Cell Function [ Time Frame: Morning before surgery and up to two days after surgery ]
    Beta cell function is measured with intravenous glucose tolerance test (IVGTT)
