This project involved exploration of a possible relationship between bariatric surgery and alcohol addiction. The literature on bariatric surgery, including techniques and outcomes on weight loss and flavor preferences in animals, was reviewed. Conditions that promote weight loss post surgery were identified as well as the concomitant shifts in digestive physiology, weight regulation, flavor preferences and their putative interactions from a flavor-feedback system model perspective. Similarly, learning of taste preference for alcohol and caloric craving in animals was reviewed and compared to the conditions involved with flavor preferences after bariatric surgery. The hypothesis that animals with Gastric Bypass surgery will have a higher susceptibility to alcohol preference post surgery was develop and various investigation approaches and predictions were considered. We propose that Gastric Bypass Surgery using the Roux-en-Y bypass method will enhance learning of calorie-based alcohol preference.
