Purpose of Study:
Learn about the benefits of gastric bypass and gastric banding surgery on body composition, the hormones that control insulin secretion and appetite, and your risk for diabetes. 

Summary:
Participants will be examined during four study periods: before gastric banding or gastric bypass surgery, one month after surgery, and one year and two years after surgery. During each study period, participants will make three separate visits in the morning to the research center for various glucose challenge tests and body composition measurements. These visits will last for about four hours.


Criteria for Participation:
Planning to have weight loss surgery
Between 21 and 60 years old
Have type 2 diabetes
All ethnic groups welcome

Benefits/Compensation:
Learn more about glucose, insulin and body composition changes after bariatric surgery and help understand why bariatric surgery may prevent and often “cure” diabetes. Partial compensation is provided to participants at the end of each study period. Total compensation for completing the study is up to $1,950.
