Study type | Observational |
This study will compare glucose and simple carbohydrate sensitivity. The hypothesis is that rapid emptying of high-glycemic index foods after Roux-En-Y gastric bypass (RYGB) causes reactive hypoglycemia. It is believed that the controlled release offered by an intact pylorus will be advantageous for long term results in bariatric surgery. This study can provide a scientific rationale, in a short duration of time, for why pylorus sparing surgery, such as the sleeve gastrectomy or duodenal switch, may offer therapeutic advantages, as compared to non-pyloric sparing surgery, namely the gastric bypass.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Mean Serum Glucose Levels | Serum glucose levels measured to assess reactive hypoglycemia status | 30, 60, and 120 minutes at 6, 9, and 12 months post-operatively | Yes |
Primary | Reactive Hypoglycemia Status | Postoperative reactive hypoglycemia was defined as either serum glucose <60 mg/dL at least 1 hour after initiation of glucose tolerance testing serum glucose decrease =100 mg/dL within 1 hour after initiation of glucose tolerance testing |
6 months, 9 months, 12 months post-op | Yes |
Secondary | Insulin Resistance | Measured by levels of post prandial insulin | 6, 9, and 12 months post-operatively | Yes |
Secondary | Subjective Symptoms of Hypoglycemia During Glucose Tolerance Testing | Subjective symptoms of hypoglycemia during glucose tolerance testing measured by patients' responses to a questionnaire about symptoms of Weakness, Nausea, Hunger, Headache, Dizziness, Diaphoresis graded on a yes/no response | 6, 9, and 12 months post-op | No |
