Abstract:
Anorexia nervosa (AN) is occasionally complicated with hypoglycemic coma, which may cause sudden death by unknown mechanisms. We present the case of a 36-year-old woman with recurrent comas and a nineteen-year history of AN. She was found in a coma with remarkable hypoglycemia (28 mg/dL). Her BMI was 11.1 kg/m2. Endocrine workup revealed extremely low serum levels of glucagon, IGF-I and insulin. Asymptomatic hypoglycemia occurred with liver injury in the refeeding process. An aberrant glucose metabolism due to liver damage might have been involved in her susceptibility to hypoglycemia. This case suggests a possible mechanism of hypoglycemic coma in AN.
