Summary

The proposed project will help to understand the changes in reinforcement and impairment experienced by Roux en Y bariatric surgery (RYGB) patients who consume alcohol. In this study the investigators propose to investigate RYGB patients with a prospective, longitudinal design. Investigators will examine driving impairment before and after surgery as well as study cognitive changes and reinforcement changes that may occur in RYGB patients while consuming alcohol. Finally, investigators aim to better characterize the changes that occur in the pharmacokinetics of alcohol following bariatric surgery and examine key variables which may play a role in the development in alcohol use disorders.

Experimental Treatment

Group I: Roux en Y Gastric BypassExperimental Treatment1 Intervention

Participants recruited for this protocol will be those planning to undergo Roux-en-Y Gastric Bypass (RYGB). Upon study screening completion, participants will take part in a total of 4 laboratory assessment days where a fixed dose of alcohol will be given. * 2 pre-surgery research appointments where participants will be given alcohol: a driving simulator day and a cognitive testing and reinforcement testing day. * 2 post-surgery (1 year) research appointments where you will be given alcohol: a driving simulator day and a cognitive testing and reinforcement testing day.
