Pregnant women with vitamin D deficiency are more likely to deliver by caesarean section (17%), compared to those with normal levels of this vitamin. This has been shown by several studies carried out by American researchers, from the Boston University School of Medicine (BUSM) and the Boston Medical Center (BMC).

The authors of these studies analyzed the relationship between the concentration of vitamin D in the maternal serum and the prevalence of cesarean section over a period of two years, observing an inverse association. That is, the lower the concentration of this vitamin in the pregnant woman, the greater the probability of having a cesarean delivery.

The function of this vitamin is to facilitate the passage of calcium to the bones and, when it is not present in sufficient quantity, calcium does not reach the bones, which weaken and begin to deform irreversibly. It is what is known as rickets, a disease that affects especially children, when they suffer from a deficit of vitamin D during its development. Although rickets almost disappeared with the discovery of vitamin D, vitamin D deficiency is currently widespread in industrialized countries. The daily requirements of vitamin D are 1000-1500 mg.
