NCT01843257

  Purpose
The investigators wish to study the effects of three forms of bariatric surgery: gastric bypass, sleeve gastrectomy, and lap banding. The surgery is not part of the clinical trial. If insurance does not cover the procedure, then the patient is responsible for payment of the surgical process. The investigators are doing pre- and post-surgery testing to provide a better understanding of the effect of bariatric surgery-induced weight loss on 1) alcohol absorption, distribution and elimination from the body; 2) the effects of alcohol on blood sugar; and 3) the effects of alcohol on mood.

Primary Outcome Measures:
  • Change from before bariatric surgery in alcohol's Tmax, Cmax, area under the curve and elimination rates at approximately 9 months after bariatric surgery [ Time Frame: Subjects in the longitudinal arm of the study will be assessed before surgery and approximately 9 months after surgery. A group of subjects will be assessed 1-5 years after surgery only. ]
    Time to reach maximum peak blood alcohol levels, alcohol area under the time-concentration curve and alcohol's constant of elimination will be examined before and after surgery and compared between those who had gastric bypass versus lap banding.

  • Change from before bariatric surgery in alcohol subjective effects at approximately 9 months after bariatric surgery [ Time Frame: Subjects in the longitudinal arm of the study will be assessed before surgery and approximately 9 months after surgery. A group of subjects will be assessed 1-5 years after surgery only. ]
    Validated instruments (such as the Addiction Research Center Inventory) will be used to measured alcohol's subjective effects at different timepoints after drinking an alcoholic or a non-alcoholic (control) beverage.


Secondary Outcome Measures:
  • Change from before bariatric surgery on alcohol's effects on glucose homeostasis at approximately 9 months after bariatric surgery [ Time Frame: Subjects in the longitudinal arm of the study will be assessed before surgery and approximately 9 months after surgery. A group of subjects will be assessed 1-5 years after surgery only. ]

Groups/Cohorts Assigned Interventions
Gastric Bypass longitudinal
Morbidly obese subjects undergoing gastric bypass surgery. Subjects will be assessed in two testing sessions about 1 week apart, in which their response to alcohol or nonalcoholic (placebo) beverage will be evaluated in a randomized cross-over fashion before surgery. The two testing sessions will be repeated ~ 9 months after surgery.
Other: Alcohol challenge test Alcohol visit first
Subjects will be assessed in two testing sessions about 1 week apart, in which their response to alcohol or nonalcoholic (placebo) beverage will be evaluated in a randomized cross-over fashion (visit 1 alcohol, visit 2 placebo).
Other: Alcohol challenge test Placebo visit first
Subjects will be assessed in two testing sessions about 1 week apart, in which their response to alcohol or nonalcoholic (placebo) beverage will be evaluated in a randomized cross-over fashion (visit 1 placebo, visit 2 alcohol).
Gastric Banding longitudinal
Morbidly obese subjects undergoing laparoscopic gastric banding surgery. Subjects will be assessed in two testing sessions about 1 week apart, in which their response to alcohol or nonalcoholic (placebo) beverage will be evaluated in a randomized cross-over fashion before surgery. The two testing sessions will be repeated ~ 9 months after surgery.
