During pregnancy, pregnant women should regularly go to the hospital for prenatal and prenatal check ups. Regular prenatal check ups are beneficial for the physical health of pregnant women and can also detect the growth and development of the baby. In order to judge the development of the fetus, data measurements will be taken on the fetus's body. Is a biparietal diameter of 39mm at 18 weeks normal?
The biparietal diameter refers to the length of the widest left and right sides of the fetal head, and a biparietal diameter of 39mm at 18 weeks is normal. In theory, a biparietal diameter of 40mm at 18 weeks is normal. If the mother is worried about it being too small, she can eat more nourishing foods. Long term biparietal diameter deviation is not friendly to the fetus, so it is recommended to eat more calcium rich and nutrient rich foods.
During pregnancy, mothers should not overeat. What problems may occur if pregnant women become obese?
1. Diseases that occur during pregnancy. Many mothers have diseases that have never occurred before during pregnancy, such as pregnancy diabetes and pregnancy hypertension. If obesity occurs during pregnancy, pregnancy diseases will be more likely to occur.
2. Difficulty in childbirth. Supplementing too much nutrition during pregnancy can lead to obesity, and babies can also absorb a lot of nutrients, resulting in obesity. The larger the baby, the more difficult it is to give birth naturally, increasing the risk of difficult childbirth. At the same time, obesity leads to an increase in body fat, which can easily cause uterine contractions and weakness during delivery.
