Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: CGM in a population with normal OGTT
A non-randomized, days 1-7 blinded, and days 8-14 non-blinded Dexcom G4 (CGM) trial.
Each subject will sample capillary blood with the HemoCue meter and measure the concentration of glucose, minimum 3 times per day for 14 days.
|
The population with normal OGTT will use CGM and document their values as well as be documenting a capillary blood glucose value
|

Difference in standard deviation of glucose levels measured by CGM between day 1-7 and day 8-14
|
Day 1-7 and day 8-14
|
The evaluation of experience of the CGM, glucose monitoring systems.
Time Frame: Week 2, day14
|
Evaluation of the Dexcom G4 system from questionnaire regarding the following questions, 1. The visual analogue scale 1-100 mm. How do you experience the benefits of seeing your daily blood glucose profile with the help of CGM (continuous glucose monitoring)? The evaluation of questions of the Dexcom G4 system were expressed on a 0-100 scale with lowest value (0) equaling to Not rewarding at all and highest value (100) equaling to completely rewarding. 2. Do you consider the CGM can be a great educational tool for patients who are at risk for getting diabetes? (yes, no) 3. Can CGM give you a mindset about diet and lifestyle changes? (yes, no) 4. Can you describe your experiences using CGM? |
