Insulinomas are uncommon neuroendocrine tumors and metastatic disease is extremely rare. We report a patient with metastatic insulinoma associated with multiple endocrine neoplasia type 1 presenting with hypoglycemia following sleeve gastrectomy. Potential causes of hypoglycemia include dumping syndrome, noninsulinoma pancreatogenous hypoglycemia syndrome, and rarely insulinoma. MEN1‐associated insulinomas have a higher recurrence rate.
