Effect of Roux-en-Y gastric bypass on pharmacologic dependence in obese patients with type 2 diabetes.

Background: More than half the diabetes-related health care costs in Canada relate to drug costs. We aimed to determine the effect of Roux-en-Y gastric bypass (RYGB) on the use of insulin and orally administered hypoglycemic medications in patients with diabetes. We also looked to determine overall cost savings with the procedure.
