研究概览
简要总结
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.
详细描述
Bariatric surgery is the most effective weight loss therapy for obesity. However, the mechanisms responsible for decreased food intake are incompletely understood. One possible mechanism that could account for decreased food intake is changes in taste perception. Therefore, the primary goal of this proposal is to provide a better understanding of the effects of bariatric surgery-induced weight-loss on taste perception.

结局指标
主要结局
Changes on Taste Detection Thresholds After Bariatric Surgery-induced Weight Loss (Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Banding).
时间窗: we will measure the above outcomes before surgery and at 20% weight loss post surgery, which on average we expect will occur around 3 months post-surgery
-Taste detection thresholds measures the lowest concentration of a tastant that can be detected (mili molar amounts).
次要结局
- Changes on Emotional, External and Restricted Eating Behavior and Food Craving After Bariatric Surgery-induced Weight Loss (Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Gastric Banding).(we will measure the above outcomes before surgery and at 20% weight loss post surgery, which on average we expect will occur around 3 months post-surgery)
