چکیده
Calcium is an essential nutrient during pregnancy and lactation. Calcium contributes to bone development in the fetus and neonate and is considered a critical nutrient. Physiological changes in calcium metabolism occur during pregnancy and lactation. Some women may lose some of their bone density during pregnancy and/or lactation, and then regain it after the cessation of lactation. Implications for childbirth educators include content regarding the topic of calcium in their classes.

Calcium in pregnancy and lactation.
Pregnancy and lactation are periods of high calcium requirement. This review highlights recent advances in our understanding of calcium and bone metabolism during human pregnancy and lactation and discusses the findings in relation to the calcium nutrition of the mother. The evidence indicates that pregnancy and lactation are characterized by physiological adaptive processes that are independen...
متن کاملNutrition in Pregnancy and Lactation
Significant changes in maternal calcium metabolism occur during pregnancy and lactation. These changes provide a sufficient calcium supply to the fetus for skeletal growth and to the newborn infant in the form of adequate maternal milk production. There is increasing evidence that calcium is mobilized from the maternal skeleton for milk production and is replaced upon resumption of menses, and ...
متن کاملEffects of cadmium intake on bone metabolism of mothers during pregnancy and lactation.
Cadmium (Cd) is a heavy metal that exists ubiquitously in the environment, and it interacts with essential elements such as zinc, copper, iron, and calcium (Ca). Particularly, Cd interferes with Ca and vitamin D metabolism in bone kidney and intestine. The interaction between Cd and Ca in bone, intestine, and kidney may result in the disorder of bone metabolism. On the other hand, pregnancy and...
متن کاملMaternal Mineral and Bone Metabolism During Pregnancy, Lactation, and Post-Weaning Recovery.
During pregnancy and lactation, female physiology adapts to meet the added nutritional demands of fetuses and neonates. An average full-term fetus contains ∼30 g calcium, 20 g phosphorus, and 0.8 g magnesium. About 80% of mineral is accreted during the third trimester; calcium transfers at 300-350 mg/day during the final 6 wk. The neonate requires 200 mg calcium daily from milk during the first...
متن کاملCalcium and bone disorders during pregnancy and lactation.
Mineral metabolism in the mother must adapt to the demand created by the fetus and placenta, which together draw calcium and other minerals from the maternal circulation to mineralize the developing fetal skeleton. Similarly, mineral metabolism must adapt in the lactating woman to supply sufficient calcium to milk and the suckling neonate. Potential adaptations include increased intake of miner...
