Oral Glucose Tolerance Test (OGTT)
- This is a standard test in the diagnosis and management of Type 2 diabetes.
- The OGTT involves placing an IV. This process involves inserting a thin tube, called a cannula, into a vein. This allows for multiple blood draws without the need for multiple needles.
- There will be 6 blood draws over the course of 2.5 hours.
- The blood draws take place before consuming a sugary drink and after. This is to get a baseline and then to measure the changes, if any, that occur.
- There will be an OGTT at visits 3 & 7.
Continuous Glucose Monitor
- Continuous glucose monitoring (CGM) is a method used to track glucose levels throughout the day and night. The continuous glucose monitor used in this study is the FreeStyle Libre.
- The small, circular device has a sensor wire that gets placed under the skin. The device stores glucose readings that can be transferred to mobile phones.
- You will wear sensors on 2 occasions over the course of the study, at visits 2 & 6.
- Each sensor lasts for 14 days.
