[Diabetes mellitus type 2].

SUMMARY: Type 2 diabetes represents the most common form of carbohydrate disorders affecting at least 5% of the population in the industrialized world. In addition to genetic predisposition obesity and a sedentary lifestyle are the main promoters. Recent data clearly suggest that lifestyle intervention in people at increased risk can potently reduce the incidence of the disease. In overt type 2 diabetes, good glycaemic control and aggressive management of associated cardiovascular risk factors may prevent its multiple and costly complications.
