Hyperinsulinism due to dumping syndrome following gastric surgery is an uncommon condition. It is specified with hypoglycemic attacks. However, linking symptoms to dumping syndrome in each patient to whom gastric surgery was performed leads to inappropriate diagnosis and therapy. Insulinoma and other causes that give rise to hyperinsulinemia should not be ignored and these diagnoses should be excluded. In this paper, 71-year-old male patient who was followed up for 2 years with a false conclusion of dumping syndrome and operated on due to insulinoma diagnosed at endoscopic ultrasonography is presented in the light of the literature.
