Insulin resistance and consequent hyperinsulinemia present a frequent disorder and according to some investigations it is present in a quarter of whole population. Leaving aside numerous genetic syndromes caused by pronounced insulin resistance, this paper surveys the influence of specific arrangement of fat tissue in the development of this disorder, its role in insulin-independent form of diabetes, development of lipidic and lipoproteinic disorders, in the essential arterial hypertension, and finally, in the appearance of accelerated and premature atherosclerosis.
