Autoimmune antibodies, induced by exogenous insulin preparations, may result in labile glucose control and frequent hypoglycemia in some rare cases. In addition to insulin cessation, immune suppressants and/or plasmapheresis have been used as the primary remedies for these patients. Some previous studies also indicate that the condition tends to remit spontaneously after discontinuation of insulin exposure. Because of this, the clinical importance of nutritional interventions and behavioral approaches, which may play a role in ameliorating the symptoms, should also be emphasized. Herein, we report on a 64-year-old man with hypoglycemia induced by insulin antibodies (IAs), whose hypoglycemic symptoms significantly improved after the implementation of nutrition therapy. This rare case expands our knowledge of the management of hypoglycemia, and for the first time highlights the significance of nutritional and lifestyle intervention in treatment of IA-induced hypoglycemia.   Key teaching points: • Exogenous insulin administration may induce autoimmune antibodies to insulin, leading to frequent hypoglycemia. • We report a case with frequent hypoglycemia caused by IAs after exogeneous insulin exposure. • The patient's symptoms were alleviated by nutrition therapy. • We demonstrate for the first time the significance of dietary and behavioral interventions in management of IA-induced hypoglycemia. © 2016 Taylor & Francis.
