Factitious hypoglycemia is a covert attempt to lower the blood glucose concentration with insulin of a sulfonylured agent. This attempt is mainly performed by the patients themselves. In a large series of diabetics who had overdosed on drugs, less than 5% had used insulin for suicidal or homicidal purposes. Additionally, 4 of 204 hypoglycemic episodes were due to a suicide atempt with insulin. The onset of insulin action, its peak level, and duration, and the degree of hypoglycemia, are determined by insulin's pharmacokinetics. However, the final outcomes are not associated withthe amount of insulin used. The complication related to insulin overdose are cerebral damage and hypokalemia. Other complications include, pulmonary edema attributed to congestive heart failure and hypertensive crisis, as well as respiratory insufficiency. We report this case with a review of the literature.
