[Facticious hypoglycaemia and diabetes: diagnosis difficulty]

ABSTRACT

There are many facticious diseases, and their diagnosis is often difficult, facticious hypoglycaemia due to auto-administration of insulin or secondary to insulin secretagogues drugs are probably under estimated. We report the case of a 25 years old woman who presents a particular facticious hypoglycaemia. she pretends to be treated for diabetes with insulin injection for 2 years. We suspect the [facticious diabetes] since she has normal fasting blood glucose level and without hyperglycaemia after her hypoglycaemic episodes, we decided to stop insulin injections, and realize that hypoglycaemia only happen when her husband comes and disappear when she has no visitors. Insulinemia and C-peptide coupled of the blood glucose level in addition to the oral provocated hyperglycemia confirm the diagnosis of facticious hypoglycaemia. the patient denied the insulin injection and we concluded she has a Munchhausen syndrome
