The size of the fetal biparietal diameter is a very important data during pregnancy, which is conducive to observing the development of the fetus and is an important data for determining the expected delivery date of the pregnant woman and whether she can give birth smoothly. But most pregnant women do not know what determines the fetal biparietal diameter. So, in fact, what is the relationship between the biparietal diameter of the fetus and its size?
The size of the fetal biparietal diameter is related to the duration of the fetus. Fetal biparietal diameter refers to the length of the widest part of the left and right sides of the fetus and the head. The size of the fetal biparietal diameter will gradually increase over the course of the pregnancy cycle. At around 5 months of pregnancy, the biparietal diameter is 7cm, and at 8 months, the biparietal diameter is approximately 8cm. The average increase in biparietal diameter is 0.2cm per week.
The biparietal diameter data of the fetus can help doctors observe the development of the fetus. If the fetal head is not correct, it needs to be corrected as soon as possible to help pregnant women give birth smoothly. Some people believe that biparietal diameter data can tell whether a fetus is male or female, but this idea is incorrect. It is unscientific to judge gender based on biparietal diameter.
But biparietal diameter data can calculate the weight of the fetus. The fetal weight is calculated by multiplying the biparietal diameter data by 900-5200, and pregnant women can adjust their nutrition based on the calculated data. Pregnant women should not blindly believe in folk remedies during pregnancy, and must regularly go to the hospital for prenatal check ups.
