25 weeks of pregnancy uterine height abdominal circumference standard

Pregnant women may experience unexpected changes in their body shape during the middle and late stages of pregnancy. Because the fetus in the pregnant woman's body is also constantly growing, the speed is unpredictable. Therefore, we usually simply measure the uterine height and abdominal circumference of the pregnant woman at 25 weeks of pregnancy. Although the situation of each pregnant woman is different, there is also a standard for reference. What is the standard abdominal circumference at 25 weeks of pregnancy?

25 weeks of pregnancy fetal abdominal circumference standard

Generally speaking, the average abdominal circumference at 25 weeks of pregnancy is normal at 19.64 ± 2.20.

Normally, the average increase in abdominal circumference is 0.85cm per week. However, the growth of abdominal circumference is unstable before 20 weeks. It grows fastest from 20 to 24 weeks, at 1.5cm per week. After 24 to 34 weeks of pregnancy, the growth rate of abdominal circumference slows down to 0.26cm.

If the abdominal circumference measured at 16 weeks of pregnancy is taken as the base number, the average growth value is 21cm by full term. Because abdominal circumference measurement is greatly affected by individual factors of the pregnant mother, when the data does not match the reference table, the pregnant mother does not need to worry too much, and should also combine other examinations for comprehensive analysis.

The role of measuring abdominal circumference during pregnancy

Observing the condition of the uterine cavity and the size of the uterus, and measuring the growth of abdominal circumference and the height of the uterine fundus can be used as one of the indicators for predicting fetal development. The abdominal circumference of the expectant mother is closely related to the size of the fetus. Measuring the abdominal circumference is mainly to understand the situation in the uterine cavity and whether the size of the uterus is consistent with the gestational age by measuring the length of the largest plane of the abdomen.

It is very important to measure abdominal circumference regularly during pregnancy. Abdominal circumference can tell us the development of the fetus. If there is any extremely abnormal situation, expectant mothers need to seek medical attention in time to further prevent the occurrence of danger. Pregnancy is the second growth period for women. In order for the baby to be born smoothly, mothers need to go to the hospital for regular check-ups to nip the danger in the bud.
