2 How much calcium should pregnant women take every day? 800 mg/day in the first trimester (0- 12 weeks). The first trimester is the period of cell division and organ initial development, and the calcium demand of pregnant women is the same as that of ordinary adults, so pregnant women do not need to supplement calcium. However, if the daily intake of calcium is less, you can drink 250ml of milk every day, eat more calcium-rich foods and get more sunshine.
Second trimester (13-26 weeks) 1000 mg/day. During the rapid growth period of the baby, the intake is increased, and 500 ml of milk or yogurt should be drunk every day. For pregnant mothers who are not used to drinking milk, about 500 mg of calcium tablets can be added every day, and then some calcium-rich foods such as dried shrimps, yuba, soybeans and green leafy vegetables can be eaten. At the same time, do some outdoor sports and get more sunshine to promote the body's absorption of calcium.
Third trimester (27-36 weeks)1200mg/day. As the baby continues to grow up, the demand for calcium increases further. Drink 500 ml of milk or yogurt every day, supplement 500 mg of calcium tablets, and eat some foods rich in calcium to achieve the required calcium.
3 How will too much calcium supplementation by pregnant women affect the baby's intellectual development? Excessive calcium supplementation by pregnant women will lead to premature calcification of fetal bones. An excellent fetal skull will not only affect the smooth production, but also lead to premature closure of the front fontanel. Generally, the fontanel of a normal baby is closed at around 1 year, which restricts the baby's brain development and affects the baby's intellectual development.
Affect the baby's height development. Excessive calcium supplementation by pregnant women will lead to premature calcification of fetal bones, which will lead to premature closure of epiphyses, which will affect the development of long bones and further limit the baby's height development.
Reduce the baby's immunity. Pregnant women supplement too much calcium. Too much calcium in the intestine will inhibit the absorption of nutrients such as iron and zinc, resulting in secondary zinc deficiency and iron deficiency, and lead to the baby's immune decline, anorexia, slow growth, anemia and fatigue.
Too much calcium supplementation in pregnant women with vascular sclerosis, which affects vision and heart function, will make the blood calcium concentration too high. Calcium will be deposited in viscera or tissues, which will affect vision if it is deposited around the cornea, affect heart function if it is deposited on the heart valve, and aggravate vascular sclerosis if it is deposited on the blood vessel wall. In addition, it will increase the risk of urinary calculi in the future.
Influence the health of pregnant women Excessive calcium supplementation can easily lead to fetal growth, difficulties in smooth delivery, hypercalcemia and even kidney calculi. In addition, when a woman is pregnant, the uterus will tilt to the right, which will press the ureter, leading to the obstruction of the right ureter, and it is easy to cause hydronephrosis during pregnancy, which seriously affects the health of pregnant women.
4 How to judge pregnant women's excessive calcium supplementation Excessive calcium supplementation will cause exophthalmos, vitamin C metabolism disorder, loss of appetite, itchy skin, hair loss and other symptoms. At the same time, if the blood calcium concentration is too high, muscle weakness, vomiting and arrhythmia will occur.
