Detailed Description
- Answer personal questions including such things as health information, eating habits and preferences, activity level and intensity.
- Submit a first stool sample via a self-addressed, postage-paid kit that is mailed to you.
- Attend one of the 2 hour connection meetings based on available dates.
- The study team will collect vitals: measurements of height, weight, blood pressure, pulse, waist and hip circumference.
- You will have a Blood collection for study (approximately 35 ml of blood/5 tubes)
- You will be provided a FitBit wrist band that you will wear
- You will be provided a manual blood glucose monitor you will use for pricking finger and measuring blood sugar level at least 4 times per day.
- You will have a continuous blood glucose sensor and monitor inserted by study staff.
- You will use DayTwo's mobile application where you will input food eaten, activity, measurements, medications, and sleep.
- You will be given a second stool kit and instructions for collection.
