`
`Brief Summary:
`Post-gastric bypass hyperinsulinemic hypoglycemia is a recently described disorder occurring in some patients after
`gastric bypass surgery for obesity. The pathogenesis is incompletely understood but involves a robust insulin response
`to ingested carbohydrate. The resultant hyperinsulinemia sometimes produces hypoglycemia with neuroglycopenia,

`confusion and even loss of consciousness. Various treatments have been recommended including low carbohydrate
`diets, coingestion of the medication acarbose with carbohydrate containing meals, partial pancreatectomy and even
`total pancreatectomy. None is completely satisfactory. We propose to test two new potential treatments. Using a design
`with random assignment of three conditions we plan to compare, in 10 patients with post-gastric bypass
`hyperinsulinemic hypoglycemia, a high carbohydrate test meal (control condition), a high carbohydrate test meal after
`pre-treatment with rapid acting aspart insulin (insulin condition), and a high fructose, low glucose test meal with
`carbohydrate and caloric content similar to the control meal (fructose condition).

`Detailed Description:
`Post-gastric bypass hyperinsulinemic hypoglycemia is a recently described disorder occurring in some patients after
`gastric bypass surgery for obesity. The pathogenesis is incompletely understood but involves a robust insulin response
`to ingested carbohydrate. The resultant hyperinsulinemia sometimes produces hypoglycemia with neuroglycopenia,
`confusion and even loss of consciousness. Various treatments have been recommended including low carbohydrate
`diets, coingestion of the medication acarbose with carbohydrate containing meals, partial pancreatectomy and even
`total pancreatectomy. None is completely satisfactory. We propose to test two new potential treatments. Using a design
`with random assignment of three conditions we plan to compare, in 10 patients with post-gastric bypass
`hyperinsulinemic hypoglycemia, a high carbohydrate test meal (control condition), a high carbohydrate test meal after
`pre-treatment with rapid acting aspart insulin (insulin condition), and a high fructose, low glucose test meal with
`carbohydrate and caloric content similar to the control meal (fructose condition). The hypothesis to be tested are 1)
`pretreatment with aspart insulin will prevent, or at least reduce, the occurrence of hypoglycemia and 2) substitution of
`fructose for glucose in the test meal will prevent, or at least reduce, the occurrence of hypoglycemia. Plasma glucose
`and serum insulin will be sampled before and for four hours after the three test conditions. The primary study endpoint
`will be the occurrence or not of plasma glucose < 60 mg/dL after the test meals. The control meal will be compared to
`the insulin pre-treated test meal and, in a separate comparison, to the fructose test meal. Secondary endpoints will be
`comparisons between the control and active treatments in peak postprandial serum insulin, peak postprandial plasma
`glucose, nadir postprandial plasma glucose, and the 4-hr longitudinal course of plasma glucose measurements.
