The variation of indicators that characterize skin scarring increases in patients with metabolic syndrome, which may affect the effectiveness of therapeutic measures. It has been found that pathological processes in the skin scar in the initial state correlate to the greatest extent with the index of insulin resistance, the atherogenic coefficient and the coefficient of antioxidant protection. It is proved that the effectiveness of complex physiotherapy with the addition of the internal intake of medium-mineralized water «Essentuki №17» directly correlates with an increase in tissue sensitivity to insulin and the activation of antioxidant enzymes, as well as with a decrease in dyslipidemia. Linear regression equations are presented to determine significant predictors of treatment effectiveness, which can lead to the creation of individualized therapeutic programs using preformed and natural physical factors.
