[A twelve-year old girl with diabetes mellitus type 2]

A 12-year-old very obese girl was referred for hyperglycaemia. She had no complaints apart from a recent vaginal candidiasis. Non-insulin-dependent diabetes mellitus (type 2 diabetes) was diagnosed. She was started on a hypocaloric diet and on an oral hypoglycaemic agent (metformin 500 mg/day). This case illustrates the importance of awareness of the existence of type 2 diabetes in childhood and adolescence.
