Recently, when visiting the clinic, I am often asked the question of calcium supplement during pregnancy, and the answer is as follows:
1. Does every pregnant woman need calcium supplement after entering the middle and third trimester of pregnancy?
Yes, most pregnant women need extra calcium. From a fertilized egg in the first trimester of pregnancy to a full-term child, A lot of calcium is needed to help children grow bones and teeth. According to dietary surveys, The daily calcium intake of Chinese women during pregnancy is about 300-400 mg, Even in Western women who consume more calcium, The average daily calcium intake during pregnancy is only about 800 mg, which is lower than the recommended daily calcium intake of 1,000-1200 mg in the second and third trimester of pregnancy. If there is a lot of milk and dairy products (such as yogurt and cheese) in the food eaten every day, there is no need for additional calcium supplement, but most people cannot do it.
2. Do you need vitamin D while supplementing calcium?
Yes, one of the main functions of vitamin D is to help the absorption and utilization of calcium. If vitamin D is not supplemented with calcium, the absorption and utilization of calcium will be affected to some extent. In addition, vitamin D has additional benefits for the skin and eyesight of mothers and children.
3. Which calcium preparations are better?
The absorption rate of most calcium agents is basically the same, so don’t believe the exaggerated and deceptive nonsense in those advertisements. The important thing is that the content of calcium in calcium agents is real, and the production process of calcium agents is safe.
4. Will continued calcium supplement in the third trimester of pregnancy cause the fetal head to be too hard to give birth?
When calcium deficiency is obvious, the fetus’s head will be softer, However, eating more calcium will not cause the fetal head to be too hard. There is no need to worry that the fetus will not be born with a hard head or a large biparietal diameter. Unlike adults, The cranial suture of the fetus is not closed. Under the pressure of the birth canal, the cranial suture of the fetus can overlap and the biparietal diameter becomes smaller, thus smoothly delivering from the vagina. Therefore, the head of the child delivered through the vagina is often [long] and becomes [round] after a few days. Your worry, the worry of Wang Dama next door, God has already thought of a good solution for you.
5. It is said that calcium supplement will age the placenta?
First, calcium supplement will not cause placental aging.
Second, there is no inevitable link between the so-called [placental aging] and the birth and prognosis of the child.
