Polycystic ovary syndrome (PCOS) is a neuroendocrine syndrome characterized by a menstrual cycle disorder mainly in the form of oligoopsomenorrhoea or amenorrhoea, hyperandrogenism, infertility, changes in metabolic parameters against the background of a large number of cystic-atretic follicles in the ovaries. One of the pathophysiological links in the development of the syndrome is a violation of the circadian rhythm of the secretion of gonadotropin-releasing hormone (LH-RH), as a result of which the production of luteinizing hormone (LH) increases and the secretion of follicle-stimulating hormone (FSH) is limited. Under the action of FSH, aromatases and enzymes that transform androgens into estrogens are formed in the granulosa cells of the ovaries. In PCOS, there is a deficiency of FSH and an excess of LH, due to which the ovaries produce an increased amount of androgens . Patients with PCOS who suffer from obesity develop insulin resistance (IR), which in this case is manifested as a result of a decrease in the immune response to circulating insulin. Summarizing all the studies, several mechanisms of IR formation in patients with PCOS can be distinguished: genetic predisposition, violation of insulin secretion by beta cells of the pancreas, peripheral insulin resistance caused by the action of androgens on skeletal muscles, violation of insulin metabolism in the liver, serine phosphorylation of the insulin receptor, and others disturbance in the way of insulin signal transduction into the cell. An important role in the development of IR belongs to hyperandrogenism , since androgens change the structure of muscles due to the predominance of type 2 muscle fibers, which are less sensitive to insulin. History of obesity, most often visceral, worsens insulin sensitivity in approximately 50% of patients . Insulin also increases the activity of cytochrome P450c17, increasing the production of ovarian and adrenal androgens . Тaking into account the importance of the correction of metabolic parameters in PCOS, a number of measures of both medicinal nature and non-medicinal means (diet therapy, physical exercise, phytotherapy) are proposed [7,8]. Diet therapy is appropriate as the first stage of treatment in patients with PCOS and IR, but the optimal diet has not been determined at the moment . Also, for the first stage of treatment, it is recommended to use metformin, but this drug is not without side effects/
