How to calculate fetal weight
During pregnancy, it is very necessary to pay attention to the growth of fetal weight. However, many women do not know how to calculate the expected weight of the fetus, which brings many difficulties to pregnancy management. This article explains how to calculate fetal weight so women can better understand how their pregnancy is progressing.
1. Predict fetal weight through ultrasound examination
To calculate fetal weight, doctors often use ultrasound technology. The weight of the fetus can be predicted very accurately by ultrasound. Typically, doctors use a preset formula to calculate the expected weight of the fetus based on parameters such as the fetus\’ head circumference, abdominal circumference, and femur length. However, this method still has a certain amount of error because the weight and length of each fetus is different.
2. Use the pregnancy weight management chart
The Pregnancy Weight Management Chart is a tool to calculate fetal weight based on Chinese women\’s height, weight and pregnancy period. Using this management form, you only need to enter your height and pregnancy period to get your expected pregnancy weight gain and fetal weight gain percentage. This method is very convenient, but it only works for Chinese women and does not provide specific fetal weight numbers like ultrasound.
3. Predict fetal weight through computer program
Using a computer program is another reliable way to predict fetal weight. A computer program generates an expected fetal weight based on information about the mother, such as height, weight and gestational age, and information about the fetus, such as head circumference, abdominal circumference and femur length. Although this method appears to be very accurate, it still has a certain amount of error.
4. Observe with the naked eye
In certain situations, doctors and midwives can use visual inspection to predict fetal weight. They predict the baby\’s weight by looking at the mother\’s weight and size during pregnancy, and the baby\’s movement and position. This method is not accurate but can be useful in certain situations, such as in medically restricted settings.
Summary
During pregnancy, it is important to know how your baby is gaining weight. This article describes four methods of calculating fetal weight, including ultrasound, pregnancy weight management charts, computer programs, and visual inspection. As we have seen, each method has its advantages and disadvantages, so it is necessary to choose the method that suits you best for calculating fetal weight. No matter which method you choose, it\’s best to maintain good eating habits and a healthy lifestyle to ensure that both you and your child are healthy.
