1, the best time for pregnant women to supplement calcium for one day.
The best time for pregnant women to supplement calcium in a day is before going to bed, because the blood calcium level of pregnant women is generally higher during the day and lower at night. At night, especially in the middle of the night and early morning, hypocalcemia can stimulate the secretion of parathyroid hormone, accelerate the decomposition of bone calcium, produce decalcification, cause hypocalcemia, and even lead to convulsions in severe cases. Therefore, supplementing calcium before going to bed can provide calcium source for hypocalcemia at night, block the use of storage resources-bone calcium in the body, and supplement calcium at night can also be used.
2. Three stages of calcium supplementation for pregnant women
Early pregnancy (0- 12 weeks)
800 mg per day. 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. Pregnant women should not supplement calcium after meals.
It is not good for pregnant women to supplement calcium after meals, because taking calcium tablets immediately after meals, calcium will combine with oily foods to form soap calcium, leading to constipation, and will combine with vegetable foods to form calcium oxalate, forming stones, which are not conducive to the absorption of calcium. Although some calcium supplements are written to be taken after meals, their main purpose is to prevent calcium tablets from irritating gastric mucosa, so it is best to supplement calcium between meals.
4. Tips
Calcium supplementation for pregnant women must be carried out under the guidance of a doctor, not as much as possible. Too much calcium supplementation will lead to premature closure of the fontanel after the baby is born. Generally, normal babies will close the fontanel at about one year old, but the fontanel will close soon after the baby whose mother has too much calcium supplementation is born, which will lead to the decline of the child's intelligence.
