Hypoglycaemia: possible mediation by chromium salt medication.

Drugs are the commonest cause of hypoglycaemia in patients without diabetes mellitus. However, in spite of this, a recent review highlighted the poor quality of evidence available supporting the association between numerous drugs and hypoglycaemia. In the context of the increasing use of nutritional supplements, appreciation of their potential side effects is ever more important. We report an unusual case of hypoglycaemia which occurred during self-administration of chromium salt supplements, and which has not recurred following supplements discontinuation.
