Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study to compare the typically prescribed dose of metformin (1000mg twice a day) with a higher dose of metformin (1350mg twice a day).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Based on the investigators previous studies of young people who take metformin, the study team found that young people's bodies process metformin faster than older people and young people may need higher doses of metformin for the best treatment outcomes. The purpose of this study is to compare the typically prescribed dose of metformin (1000mg twice a day) with a higher dose of metformin (1350mg twice a day).
