Many expectant mothers will have regular prenatal checkups during pregnancy. The main purpose of prenatal checkups is to check whether the baby is growing healthily. Secondly, the amniotic fluid of the pregnant mother can be checked to determine which trace elements are still lacking in the baby's growth. Checking the uterine height and abdominal circumference is also an item that must be checked at every prenatal checkup. So what are the standard values ​​of uterine height and abdominal circumference at 24 weeks of pregnancy? The editor will give you a detailed introduction below.

Standard value of uterine height and abdominal circumference at 24 weeks of pregnancy

The enlargement of the uterus during pregnancy is regular, mainly manifested by an increase in the fundus of the uterus and an increase in abdominal circumference. The measurement of uterine height and abdominal circumference generally starts from the 20th week of pregnancy, once every 4 weeks, once every 2 weeks from 28 to 35 weeks of pregnancy, and once a week after 36 weeks of pregnancy. Under normal circumstances, the average growth rate is 1 cm per week starting from the 21st week, and the average growth rate is 0.65 cm per week starting from the 34th week. The standard value of abdominal circumference at uterine height at 20 weeks of pregnancy is 16.0-20.5CM, and the standard value of abdominal circumference at uterine height at 24 weeks of pregnancy is calculated to be 20.0-24.5cm.

How to measure uterine height and abdominal circumference

1. Measurement of palace height. When measuring uterine height, pregnant women need to empty their bodies of urine first, then lie flat on the bed, and then use a soft tape measure to measure the distance from the midpoint of the upper edge of the pubic symphysis to the fundus of the uterus. Every time we measure the uterine height and abdominal circumference, we can write all the values ​​on the uterine height pregnancy chart to observe whether the fetal development is consistent with the gestational age. If we find that it does not match the gestational age, or is too large or too small, we need to find the reason.

2. Measurement of abdominal circumference. Abdominal circumference mainly measures the length of the waist and abdomen from the navel to the waist. When measuring, make the lower part of the tape measure completely close to the body, but do not tighten the abdomen. Understand the size of the transverse diameter of the uterus and the corresponding height of the uterine fundus in order to understand the situation inside the cavity and whether the size of the uterus is consistent with the gestational age.

The above is the editor’s introduction to the standard values ​​and measurement methods of uterine height and abdominal circumference at 24 weeks of pregnancy. Expectant mothers may wish to try to measure the uterine height and abdominal circumference by themselves. However, since the measured value is greatly affected by the individual factors of the pregnant woman, when the value is different from the standard value, expectant mothers do not need to worry too much and can go to the hospital for an ultrasound examination to confirm.
