The possible role of stress induced hormonal disbalance in the patophysiology of insulin resistane in lean individuals.

Abstract：

:Insulin resistance (IR) is a common denominator of metabolic and hemodynamic disorders simultaneously present in one person and responsible for elevated risk of developing type 2 diabetes (T2DM) and cardiovascular incidents. According to the latest research, IR is present in 25-45% of the general population. Therefore, the mechanism of its development is in the center of scientific and professional interest. Established or acquired factors, or combinations thereof, which disturb any step of the physiological insulin action mechanism: its binding to the cellular receptor, through the complex cascade of intracellular signaling pathways might cause IR. Although the adiposity and its underlying risk factors are considered to be the primary cause of IR, it is present in a great porportion in lean individuals as well. There are insights of the possible role of psychological factors: exposure to stress and deprssion to IR development, although the mechanism of this relationship has not been comperhensively studied. Data driven from cell cultures and experimental animal models suggest that there is an elevated level of counter-regulatory insulin hormones: growth hormone, prolactin and cortisol due to acute stress exposure. However, the relationship between these psychological disorders with the hyperreactivity of the axis of the hypothalamic-pituitaryadrenal axis as the underlying mechanism in the patophysiology of IR in lean individuals has not been systematically investigated. Based on the aforementioned, we hypothesise that this mechanism would be responsible for the formation of IR, and consequently, T2DM in lean individuals. The possible effect of the amount of stress in conjunction with the serum concentration of growth hormone, cortisol, prolactin and dehydroepiandrostendone to the abnormal 5-h oral glucose tollerance test results could contribute to the primary prevention of diabetes and its complications.
