Taste Perception Pre and Post Bariatric Surgery

Completed

Conditions studied: Morbid Obesity

In brief

The investigators wish to study the effects of three forms of bariatric surgery, gastric bypass lap banding, and sleeve gastrectomy. The surgery is not part of the clinical trial. If your 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 taste perception.
