Comparison table of biparietal diameter and gestational age

The comparison table between biparietal diameter and gestational age can help expectant mothers understand the development of their babies at different stages. The following is a detailed comparison table: The average biparietal diameter of gestational age is 13 weeks 2.52 ± 0.2514 weeks 2.83 ± 0.5715 weeks 3.23 ± 0.5116 weeks 3.62 ± 0.5817 weeks 3.97 ± 0.4418 weeks 4.25 ± 0.5319 weeks 4.52 ± 0.5320 weeks 4.88 ± 0.5821 weeks 5.22 ± 0.42 Generally speaking, after the fifth month of pregnancy, the biparietal diameter of the fetus is basically consistent with the month of pregnancy, that is, the fetus is about 7cm long in the seventh month of pregnancy, about 8cm long in the eighth month of pregnancy, and so on. At term, the biparietal diameter can reach 9.3cm or more. It should be noted that the biparietal diameter is only a reference data, and each baby\’s development situation is different. If the baby\’s biparietal diameter is too large, it is best for the pregnant mother to go to the hospital for a B-ultrasound to check whether there is water accumulation in the fetal brain. If not, you should be careful. The size of the fetus is too large, which will increase the difficulty of normal delivery. Pay attention to balanced nutrition and exercise more to improve this situation. If the biparietal diameter is small and there are no other abnormalities, don’t worry. Just pay attention to strengthening nutrition, eating more high-protein foods, and having regular prenatal check-ups. During pregnancy, expectant mothers need to pay attention not only to the size of the biparietal diameter, but also to maintain good living and eating habits to ensure the healthy development of the baby. As the old saying goes: \”If you don\’t accumulate small steps, you can\’t reach a thousand miles; if you don\’t accumulate small streams, you can\’t reach a river.\” Every small detail may have a profound impact on your baby\’s future. I hope every expectant mother can take every detail of pregnancy seriously and lay a solid foundation for the healthy growth of her baby.
