FEATURES OF DEVELOPMENT OF NON-DEVELOPING PREGNANCY IN AN ADVERSE EPIDEMIOLOGICAL SITUATION WITH VITAMIN D DEFICIENCY

Abstract

WHO experts assess vitamin D deficiency and low supply as a new pandemic of the 21st century. Further research is needed to clarify the mechanism of the influence of low vitamin D supply on the development of pregnancy complications. Due to the increasing proportion of undeveloped pregnancies in the structure of early reproductive losses and subsequent adverse consequences, identifying risk factors is an urgent problem in practical healthcare. Deficiency of vitamins, microelements and nutrients in the modern world is a problem that is recognized as a pandemic of the 21st century, despite the development of medical knowledge and the availability of information. Recently, the role of vitamin D in reproductive medicine, obstetrics and gynecology has been actively studied. Vitamin deficiency among pregnant women in the world reaches 50-80%, which creates unfavorable conditions for the process of implantation, development of the embryo and fetus. In this regard, studying the importance of vitamin D and micronutrients in the development of non-developing pregnancy in an unfavorable epidemiological situation is justified.
