Endocrinol Diabetes Metab Case Rep. 2015;2015:150049. doi: 10.1530/EDM-15-0049. Epub 2015 Jul 15.

UNLABELLED: Post-prandial hypoglycemia is frequently found after bariatric surgery. Although rare, pancreatic neuroendocrine tumors (pNET), which occasionally are mixed hormone secreting, can lead to atypical clinical manifestations, including reactive hypoglycemia. Two years after gastric bypass surgery for the treatment...
