Comparison table of gestational age, uterine height and abdominal circumference

Pregnant women pay special attention to their own health during pregnancy, because the health of pregnant women directly affects the fetus. Many pregnant women check their various data during pregnancy. Do you know the standards and corresponding table of uterine height and fetal abdominal circumference during pregnancy? Let’s take a look with the editor.

Causes of high uterine height during pregnancy

1. The inaccurate delivery date causes errors in the uterine height data. In the early stages of pregnancy, B-ultrasound examination can help doctors predict the appropriate date of delivery. Ultrasound examinations used to estimate the date of delivery are usually performed around 12 weeks of pregnancy. If the pregnancy is very advanced, the estimated due date using ultrasound will not be accurate.

2. The waist muscles of primiparas may be looser than those of most primiparas, resulting in a higher uterine height.

3. Excessive amniotic fluid. If the pregnant woman's uterine height is high due to excessive amniotic fluid, the pregnant mother will need to regularly perform fetal heart rate monitoring and B-ultrasound examinations during the remaining pregnancy to closely monitor the growth and development of the fetus.

4. Uterine leiomyoma: At this time, you need to cooperate closely with the treatment under the specific guidance of a doctor.

5. Pregnant with twins or twin babies.

I believe that after reading this article, all pregnant friends will understand the standard value of uterine height and fetal abdominal circumference during pregnancy. Why not measure it accurately if you have time! We need to pay attention to the condition of high uterine height and high abdominal circumference of the fetus, which may be caused by some diseases. Therefore, we should seek medical attention immediately to prevent it from affecting the growth and development of the fetus.
