A characteristic reactive hypoglycemia induced by rapid change of eating behavior in anorexia nervosa: a case report.

Abstract

The relationship among reactive hypoglycemia, corresponding insulin metabolism, and eating behavior in anorexia nervosa (AN) has not been well documented.

METHOD

A 22-year-old woman with AN was admitted to Kagoshima University Hospital. An oral glucose tolerance test was performed with additional sampling at 15 minutes on the seventh hospital day when her daily caloric intake rapidly increased, reaching 2,000kcal perday.

RESULTS

An elevated level of insulin secretion (1,190pmol/L) was observed during the very early phase (15 minutes) after glucose load, whereas corresponding blood glucose elevations were not as high (1.2mmol/L). The patient experienced asymptomatic hypoglycemia (2.1mmol/L).

CONCLUSIONS

Our findings suggested that a rapid increase of energy intake might cause reactive hypoglycemia with characteristic insulin metabolism, that is, an elevated level of insulin secretion during the very early phase.
