35 weeks of pregnancy uterine height abdominal circumference standard

Everyone has a different physique and the conditions during pregnancy are also different. Regular check-ups should be done from the beginning of pregnancy. The abdomen will be noticeably enlarged three months after pregnancy, and fetal movement will be felt when the pregnancy is five months. The longer the pregnancy is, the more physical examinations and items will be required. Measuring uterine height and abdominal circumference during gestational age is also a necessary examination for pregnant women. It can determine the development, size and weight growth of the fetus in the uterus through the measurement data of the size of the uterus.

Question 1

The standard uterine height at 35 weeks of pregnancy should be 28.5-35.5cm. Basically, starting from the 20th week of pregnancy, the uterine height needs to be measured at every prenatal check-up. Simply put, it is to measure the current size of the pregnant woman's uterus. The uterine height is usually measured together with the abdominal circumference. 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. If the height of the uterine fundus does not increase for several consecutive weeks, and even the transverse diameter of the uterus does not widen, it indicates that the fetus is growing slowly. In this case, you need to consult a doctor to further find out the cause. If the uterine fundus rises too quickly, it may be caused by rapid fetal growth or excessive amniotic fluid.

Question 2

The height of the uterus and abdominal circumference of a pregnant woman are closely related to the size of the fetus. During the early and middle stages of pregnancy, there are certain standards for monthly growth, and the uterine height usually grows 1 cm per week. To the later stage. During each prenatal check-up, the uterine height and abdominal circumference are measured to estimate the intrauterine development of the fetus. At the same time, the uterine height pregnancy chart can also be used to understand the intrauterine development of the fetus and determine whether it is developmentally delayed or macrosomia, so that it may be corrected through timely treatment. If the uterine height is more than 2 cm higher than the average for the corresponding number of weeks of pregnancy, the doctor may arrange an ultrasound to find out the cause. If the uterine height is low, the abdominal circumference data should also be considered, because the different postures of the baby in the uterine cavity will also affect the uterine height data. As long as the uterine height and abdominal circumference increase, a slightly lower uterine height data can be considered within the normal range.

Question 3

The purpose of doctors regularly checking pregnant women's uterine height and abdominal circumference is to gain a general understanding of the intrauterine development of the fetus through the pregnant woman's individual data. It should be noted that if the uterine height does not change for two consecutive weeks, the pregnant mother must go to the hospital immediately for treatment.

1. Assess fetal development. Measure the height of the uterine fundus and plot the results on a pregnancy chart to see if fetal development is consistent with gestational age. If you find that the baby's pregnancy is inconsistent with the gestational age, or is too large or too small, you need to find out the cause, such as doing special examinations such as B-ultrasound to determine whether there are twins, deformities, stillbirths, too much or too little amniotic fluid, etc.

2. Estimate the due date. Another function of measuring uterine height is to predict the due date of delivery. Generally speaking, the curve of fetal uterine height changes first rises and then falls. At the end of the 4th month of pregnancy, the height of the uterine fundus is 10cm above the pubic symphysis. It continues to rise until the end of the 9th month of pregnancy, when it rises to 28-30cm above the pubic bone. However, by the end of the 10th month of pregnancy, the height of the uterine fundus will return to the height at 8 months. That is to say, as the time of birth approaches, the uterus will begin to descend, and 1-2 weeks before delivery, the fetus's head will mostly have descended into the pelvis. Therefore, the uterine height can also roughly determine whether the fetus has entered the pelvis and estimate the approximate due date.
