Study Summary

The study is being undertaken to understand how a gastric bypass can affect a subject's diabetes even prior to their losing significant amounts of weight. The hypothesis of this study is that increased glucagon-like peptide-1 (GLP-1) secretion explains the amelioration in insulin secretion after Roux-en-Y Gastric Bypass (RYGB) surgery.

Primary Outcome

The total disposition index equals the product of insulin secretion and insulin sensitivity.

Interventions
