Hypoglycemia secondary to factitious hyperinsulinism in a foster care adolescent - a case report of munchausen syndrome in a community hospital emergency department setting

摘要

Factitious disorder causing hypoglycemia is a psychiatric condition in which patients deliberately use blood sugar lowering medications to cause severe symptoms for the purposes of hospitalization or other primary gains. We report a case of factitious hypoglycemia in a 19-year-old foster care adolescent female who presented to the Emergency Department with recurrent hypoglycemic episodes, to the degree that the patient required large amounts of dextrose and further management by intensive care unit hospitalization. Further inquiry revealed that the patient intentionally injected herself with large doses of insulin for the purposes of seeking hospital admission. Factitious disorder in the setting of recurrent hypoglycemia episodes may warrant a psychiatric referral and appropriate discharge follow-up to avoid multiple hospitalizations. Presentation in a non-diabetic patient from insulin use is a type of illness that is a challenge for emergency department physicians to appropriately diagnose and treat. Classic findings include a low blood sugar level, suppressed C-peptide level, and an inappropriately elevated insulin level. Recognizing these psychiatric presentations is crucial in order to stabilize patients and prevent unnecessary testing.
