It is not clear if vitamin D supplementation, alone or in combination with calcium or other vitamins and minerals, during pregnancy have benefits or harms to the mother or her offspring. Vitamin D is essential for human health, particularly bone, muscle contraction, nerve conduction, and general cellular function. Low concentrations of blood vitamin D in pregnant women have been associated with pregnancy complications. It is thought that additional vitamin D through supplementation during pregnancy might be needed to protect against pregnancy complications.

- Vitamin D deficiency is a preventable health problem.
- It has also been linked to just about every health condition under the sun!
Obstetric endocrinology is a field characterized by opportunity, challenges and caution. Opportunity, because the antenatal period presents a window during which endocrine and metabolic manipulation can impact not only maternal and fetal health, but also long-term outcomes in offspring. Caution is necessary, too, because the same therapy may lead to unwanted adverse effects in the innocent fetus, and have as yet unknown long-term complications.
Challenges in obstetric endocrinology are unique, too, as ethical and practical issues make it difficult to conduct randomized placebo controlled trials as many situations. The rapidly increasing incidence of endocrine dysfunction in obstetrics, and the public health importance Bikini wax before and after pictures these conditions, therefore, require closer attention and debate.
Issues relates to obstetric thyroidology and gestational diabetes mellitus[ 12 ] have been discussed in the pages of Pretty chicks porn earlier. The editorial focuses on another controversial field of obstetric metabolism: Vitamin D and pregnancy. Vitamin D deficiency and insufficiency are common across the globe. Large epidemiological studies reveal the high prevalence of vitamin D in women, including antenatal and lactating mothers.
Vitamin D requirements are probably greater in pregnancy, as evidenced by physiologically higher 1,dehydroxy vitamin D levels seen in the second and third trimesters. The musculoskeletal manifestations of vitamin D deficiency are well known: Rickets and osteomalacia have been linked with the condition for nearly a century now. Myriad metabolic, nonskeletal associations of vitamin D deficiency are now being unraveled as well.
Various authors report links between low vitamin D levels and various elements of the metabolic syndrome. Yet others describe the immunomodulatory, anabolic, anti-infective and anti-tumoral potential of vitamin D. Maternal secondary hyperparathyroidism and osteomalacia, neonatal hypocalcemia and tetany, delayed ossification of the cranial vertex, enlarged size of cranial, fontanelles, and impaired fetal bone ossification has been reported by various authors, and reviewed in detail by others.
The relationship between low vitamin D and adverse maternal outcomes such as pregnancy — induced hypertension,[ 7 ] high blood pressure in diabetic pregnancy,[ 8 ] gestational diabetes mellitus,[ 9 ] recurrent pregnancy loss,[ 10 ] preterm delivery,[ 11 ] primary Caesarian section,[ 12 ] and postpartum depression[ 13 ] has been documented in recent years. Evidence has also accumulated regarding the impact of maternal vitamin D levels on long-term health of offspring[ 614 ] Data related to effects of Movies in french lick vitamin D on skeletal integrity in childhood is conflicting.
One study which assessed bone mass at 9 years of age, found a positive correlation with high maternal vitamin D,[ 15 ] whereas another analysis of the same longitudinal study could not detect any relevant association. Randomized controlled trials are available to support the need for, and benefits of, vitamin D supplementation in pregnancy. While older Latin american direct investment regulations were relatively smaller, and limited to months duration,[ 14 ] newer data proves the safety and Vitamin d in pregnancy of IU vitamin D, administered daily over 6 months of pregnancy.
Simultaneously, no adverse event due to vitamin D was documented in any subject. The study conducted by Holles et al. While there is general consensus regarding the need for vitamin D supplementation in pregnancy, there is confusion regarding optimal target levels, and the dose required to achieve them.
The optimal level of vitamin D in nonpregnant adults is defined as levels of 25 OH D which are required to maintain serum parathormone levels and prevent secondary hyperparathyroidism. Following this line of thought, normal levels in pregnancy should be the same as those in nonpregnant adults.
The added dimensions of fetal health, and later health of offspring, however, complicate the issue. Data regarding the effect of increasing vitamin D levels on birth weight, neonatal health, later health, and maternal outcomes is scarce.
This still leaves scope for better outcomes with higher levels, and further data is awaited. Three decades ago, Marya et al. Both does improved infant anthropometry, whereas the larger dose also increased maternal vitamin D levels. As we mentioned initially, obstetric endocrinology is a field marked by both opportunity and caution. With the available evidence regarding vitamin D supplementation, and the conflicting interpretations of whatever has been published, it becomes challenging to issue evidence-based guidelines.
However, the benefit of vitamin D supplementation in pregnancy is potentially even greater than in the nonpregnant state. Yet, we continue to prescribe lower doses to pregnant women than to their nonpregnant peers, perhaps because of an unfounded fear of side effects. Symptomatic or documented vitamin D deficiency in pregnant women should be treated in the same manner as in nonpregnant individuals.
In healthy, asymptomatic antenatal women, IU can be supplemented daily in the second and third trimesters, without fear of vitamin D toxicity or teratogenicity. No safety data, however, is available for the first trimester with this dose, either. Serum alkaline phosphate, a surrogate marker of vitamin D deficiency, cannot be used as such in Vitamin d in pregnancy, because of the placental secretion of this enzyme.
In routine practice, however, this investigation is not necessary. In resource constrained settings, patients on vitamin D therapy can be screened for hypercalcemia by checking for calcium crystalluria. As in other fields of obstetric endocrinology, there is an urgent need for greater research in vitamin D therapeutics in pregnancy.
Higher doses can be used in symptomatic antenatal women, and in those with documented severe deficiency. Source of Support: Nil. Conflict of Interest: None declared.

ABSTRACT: During pregnancy, severe maternal vitamin D deficiency has been associated with biochemical evidence of disordered skeletal homeostasis, congenital rickets, and fractures in the newborn. At this time, there is insufficient evidence to support a recommendation for screening all pregnant women for vitamin D deficiency. For pregnant women thought to be at increased risk of vitamin D deficiency, maternal serum hydroxyvitamin D levels can be considered and should be interpreted in the context of the individual clinical circumstance.
