Fetal abdominal circumference standard reference table

Fetal abdominal circumference standard reference table

In order to ensure the healthy growth of the fetus during pregnancy, expectant mothers need to go to the hospital for prenatal check-ups every month starting from the 12th week of pregnancy. The purpose of doing so is to better understand the growth and development of the fetus, and to rule out the occurrence of some diseases through professional examinations. Therefore, regular prenatal check-ups are very important for both the fetus and the expectant mother, and there are many items in each prenatal check-up, especially in the growth and development of the fetus. Therefore, during the prenatal check-up, expectant mothers should follow the doctor's instructions, and the purpose of each examination is different. Take the fetal abdominal circumference of the fetus as an example. What kind of examination can generally understand the fetal abdominal circumference of the fetus?

Generally, the measurement of fetal abdominal circumference begins in the 16th week after pregnancy. The expectant mother can measure it while lying down or standing up. Usually, the pregnant mother is measured while lying down during the pregnancy check-up. When measuring, a soft tape measure is usually used with the belly button as the standard, and it is measured horizontally around the expectant mother's abdomen for one week. However, because the measurement of a person's fetal abdominal circumference will be affected by the mother's own factors, when the fetal abdominal circumference result does not match the reference table, the expectant mother should not worry, but should combine other tests for comprehensive analysis.

Although the standard value of fetal abdominal circumference is not so important, pregnant women still have to have a certain understanding of the standard value of fetal abdominal circumference in clinical medicine. Before 20 weeks of pregnancy, the expectant mother's fetal abdominal circumference will increase at a rate of 0.85cm per week. During 20-24 weeks of pregnancy, the pregnant woman's fetal abdominal circumference grows faster, generally at a rate of 1.5cm per week. After 24-34 weeks of pregnancy, the growth rate of the expectant mother's fetal abdominal circumference slows down, generally at a rate of about 0.26cm. If the fetal abdominal circumference measured at 16 weeks of pregnancy is used as the number, by full term, the average growth value of the expectant mother's fetal abdominal circumference is about 21cm.

Although the changes in the fetal abdominal circumference are related to personal factors, the average growth level still requires the expectant mother to have a certain grasp. Therefore, after pregnancy, the expectant mother should also pay attention to the changes in the fetal abdominal circumference during the examination, and consult the doctor after the prenatal examination to see if the results of her prenatal examination are normal. If there are any abnormalities, there is no need to worry too much, just cooperate with the doctor.
