Reason 1: first of all, the biparietal diameter of the fetal head, that is, the BDP data we see on the B-ultrasound list or color ultrasound list, refers to the length of the widest part between the left and right sides of the fetal head. Doctors often use it to observe the development of children, to determine whether the fetal position is smooth, whether pregnant women can give birth naturally.

Reason 2: secondly, by the time of full-term pregnancy, biparietal diameter can generally reach 9.3 cm or more. Generally speaking, after 5 months of pregnancy, it is basically consistent with the month of pregnancy, that is to say, the BPD is about 7.0 cm at 28 weeks of pregnancy (7 months), 8.0 cm at 32 weeks of pregnancy (8 months), and so on. After 8 months of pregnancy, the average weekly growth of about 0.2 cm is normal.

Reason 3: finally, the average biparietal diameter of the fetus is 6.39 ± 0.70 at 25 weeks of gestation, and 6.68 ± 0.61 at 26 weeks of gestation. Therefore, at 25 weeks and 5 days of gestation, the average biparietal diameter of the fetus is about 6.59, and the deviation will not be too large. It is normal to be larger or smaller than this value by 0.65.

matters needing attention

The 25 week fetus is about 30-24 cm in length and 600-700 g in weight. Baby skin is still thin and wrinkled, almost no subcutaneous fat, but it looks fuller than last week. The whole body is covered with a thin layer of fluff. The taste buds on the fetus's tongue are forming. At 25 weeks, the development of the fetal brain has entered a peak. At this time, the brain cells of the baby rapidly proliferate and differentiate, and the volume increases. At this time, pregnant women can eat more brain healthy foods, such as walnuts, sesame, peanuts, etc.
