Hypoglycemia Worsened by Glucose Administration: A Case of Hypoglycemia Years After Gastric Surgery.

BACKGROUND: Noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS) is a rare syndrome characterized by postprandial hypoglycemia with neuroglycopenic symptoms occurring 1 to 3 h after a meal. Diagnosis can be elusive, as the vast majority of patients have normal fasting blood glucose levels, and onset of hypoglycemic episodes can be a late complication of gastric surgery.

CASE REPORT: We report the case of a 45-year-old woman presenting to the Emergency Department (ED) with new-onset seizures and hypoglycemia worsened by glucose administration. Surgical history is pertinent for a Roux-en-Y gastric bypass approximately 10 years prior to presentation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although rare, it is important for emergency physicians to be vigilant of this disease process as a traditional treatment approach for hypoglycemia may be detrimental. Although cases of NIPHS have been documented in literature, its presence in emergency medicine-specific literature is seemingly nonexistent. Noninvasive imaging techniques will be normal, and diagnosis is dependent on awareness of this disease entity coupled with a detailed history.
