Quitting Caffeine for Better Glucose Metabolism

Phase 1
Completed
Conditions
Diabetes Mellitus, Type 2
Registration Number
NCT01030796
Lead Sponsor
National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)
Brief Summary

This project is a pilot study of caffeine abstinence in coffee-drinkers who have type 2 diabetes. Evidence suggests that caffeine may impair the control of glucose levels, especially in those people who have type 2 diabetes. Eliminating caffeinated beverages from the diet might improve glucose control, but the difficulty of quitting is unknown. This pilot study will follow a small number of type 2 diabetic patients for three months after a brief intervention designed to help people quit caffeine. Data on success with maintaining abstinence and on changes in glucose control will be collected.
