Gestante e necessidade da vitamina D

Abstract

Vitamin D, when remembered by its action on calcium and phosphorus metabolism, has also been involved in control and regulation of cell growth and differentiation in many tissues, and the immune system and tumor genesis (cancer of the colon, breast, and prostate). Moreover, receptors for this hormone can be found in almost all body tissues and other actions not related to mineral metabolism have been attributed to him. Nowadays there are many studies linking the lack of Vitamin D in the body to some disease (multiple sclerosis, rheumatoid arthritis, obesity, metabolic syndrome, type 1 diabetes mellitus, systemic lupus erythematosus, osteoarthritis, inflammatory bowel disease, Crohn’s disease and ulcerative colitis). The problems go beyond impaired bone health - already established relationship, because the nutrient helps retain calcium in the bones, and deficiency (< 20 ng / ml) or insufficiency (20-30 ng / ml) associated with osteomalacia, oesteopenia, osteoporosis and increased risk of bone fractures). A vitamin D deficiency may be a risk factor for adverse pregnancy outcomes such as preterm birth, low birth weight, restriction of intrauterine growth and gestational diabetes. Therefore, prevention of vitamin D deficiency in pregnant women is essential.
