The modern strategies of clinical management of vitamin D deficiency in practices of the obstetrician gynecologist

Low vitamin D concentrations were presented in a significant proportion of the population. Many diseases in people, both middle and old, were directly associated with vitamin D deficiency. The effect of vitamin D levels on reproductive function in both men and women has been proven. Low vitamin D concentrations have been associated with a wide range of adverse maternal and offspring health outcomes in observational epidemiological studies.Complications of pregnancy with a low level of vitamin D are pre-eclampsia, gestational diabetes and premature birth. It is proved that the appointment of vitamin D to women during pregnancy reduces the proportion of cesarean section in delivery. Numerous authors prove the role of vitamin D in the pathogenetic chain of the polycystic ovary syndrome. It was found that during the menopause due to the violation of steroidogenesis there is a loss of bone mass due to vitamin D deficiency. In addition, a decrease in the level of vitamin D is associated with the occurrence of uterine fibroids.However, despite a dearth of interventional evidence supporting supplementation/treatment of vitamin D in randomised controlled trial settings, it is generally accepted that supplementation/treatment is not harmful and may have some significant short- and long-term health benefits. In this regard, timely correction of vitamin D deficiency becomes very important in solving reproductive problems. This review focuses on the problem of correcting the level of vitamin D in different population groups. Treatment of vitamin D deficient women and vitamin D supplementation is safe and is recommended for all women who are pregnant or breastfeeding.
