A 58-year-old woman was admitted to the hospital for hypoglycemia. This was her seventh admission to our institution for hypoglycemia in 2 months after multiple hospitalizations at an outside institution. She presented due to difficulty maintaining blood glucose above 60 mg/dL despite eating carbohydrates. She reported a rise in blood glucose to 80–90 mg/dL 20 minutes after eating, which dropped again 30–60 minutes later. During a span of 8 admissions, the lowest glucose measured on day of admission was <20 mg/dL, and the highest was 62 mg/dL, with most below 30 mg/dL.
