Core Tip
Core Tip: Neuroglycopenic symptoms compatible with Whipple’s triad were identified in a woman 2 years after laparoscopic sleeve gastrectomy, predominantly occurring in the fasting state. After discarding late dumping syndrome, a 72-h fasting test was performed and tested positive. Imaging techniques documented the presence of a tumoral lesion in the pancreas, compatible with insulinoma. After laparoscopic enucleation of the insulinoma, the symptoms were relieved. When hypoglycemia occurs after bariatric surgery, evaluation of insulin secretion is needed to conduct a correct diagnostic approach. Follow-up must be performed by a multidisciplinary team.
