Influence of Preprandial Metformin Administration on Carbohydrate Absorption (METTIME)
Influence of Preprandial Metformin Administration on Carbohydrate Absorption: Pilot Randomized Controlled Study
Type 2 diabetes is spreading worldwide as well as obesity. Metformin is the most prescribed antidiabetic medication. One suggested mechanism of action is by decreasing carbohydrate absorption.
It is usually recommended to take metformin during the meal to decrease gastrointestinal side effects. However, if metformin decreases carbohydrate absorption, this might not be the most efficient intake.
To study the influence of preprandial metformin administration on carbohydrate absorption, it will repeat 3 oral glucose tolerance test on obese dysglycemic patients, without metformin or with metformin administer 30 or 60 minutes before. We will also evaluate how it impacts gastrointestinal tolerance.

Intervention / Treatment |
---|---|
Experimental: taking metformin 30 or 60 minutes before the OGTT

Each participant will have 3 OGTT, one without metformin, one with metformin30 minutes before the test, one with metformin 60 minutes before the test.
The order for each test will be randomized.
