Resum
[eng] Obesity-associated insulin resistance and hyperinsulinemia are two interrelated health conditions that have become increasingly prevalent in recent years. For many years, it has been thought that hyperinsulinemia comes after insulin resistance. The truth is that recent data suggests that insulin resistance can follow hyperinsulinemia and vice versa. Obesity is commonly associated with insulin resistance and hyperinsulinemia, but although some molecular mechanisms have been proposed, there is no clear evidence as to which condition occur before in humans. Despite much controversy over the timing of the onset of hyperinsulinemia in obesity, it is well established that the presence of insulin is necessary for obesity to occur and that chronically
elevated insulin levels enhance diet-induced obesity. Therefore, the aim of this review is to provide a comprehensive up-to-date on the molecular mechanisms underlying hyperinsulinemia and the relationship between hyperinsulinemia and insulin resistance in obesity. In addition, we will examine the role hyperinsulinemia plays in cellular senescence, cancer and in dysregulating the insulin/IGF-1/GH axis. Finally, we will discuss possible current therapeutic strategies targeting hyperinsulinemia that are being used to treat obesity-associated insulin resistance, including current pharmacological therapies, the effects of multiple dietary interventions, physical exercise, and surgery. We conclude that hyperinsulinemia is a prevalent
condition in obesity, but its time of occurrence and relationship with obesity are still under investigation. Dietary interventions, particularly low glycemic load diets and low carbohydrate diets, as well as regular exercise have shown promise in reducing hyperinsulinemia, while the long-term efficacy and potential side effects of pharmacological interventions require further study.
