Fetal weight growth chart in late pregnancy

Many pregnant parents are very concerned about the growth and development of the fetus, and will do various pregnancy tests during pregnancy to check whether the fetus is growing and developing normally. Many pregnant parents want to know the weight of their fetus. Do you know the formula for calculating the weight of your baby during pregnancy? How should the weight of the fetus be calculated?

Estimating the baby's weight does not mean the exact weight of the baby when it is born. The purpose of predicting the baby's weight is to detect any problems in the baby's development as early as possible. Generally speaking, there will be a deviation of ±10-15% between the actual weight at birth and the predicted weight. For example, if the birth weight is 4000 grams, the deviation range will be 400 grams. In other words, the larger the newborn's weight, the greater the deviation range. The following is only a general method for calculating the baby's weight in obstetrics and is for reference only:

Formula calculation 1: Baby weight (g) = -4973.72 260.69 periodontal HC (baby head circumference).

Formula calculation 2: Baby weight (g) = -2686.60 171.48 periodontal AC (fetal abdominal circumference).

Formula calculation 3: Baby weight (g) = -2232.56 747.42 periodontal FL (fetal femur length).

Formula calculation 4: baby's weight (g) = -2513.51 1049.90 periodontal FTH (the thickness of fetal foot fat).

Formula calculation 5: baby weight (g) = -5168.32 100.97 periodontal HC (baby head circumference) 110.86 periodontal AC (fetal abdominal circumference) 143.09 periodontal FL (fetal femur length) 331.43 periodontal FTH (fetal foot fat thickness).

Formula calculation 6: Baby weight (g) = 900 periodontal BPD (fetal biparietal diameter) - 5200.

Formula calculation 7: Baby weight (g) = 2900 0.3 periodontal uterine floor height periodontal hip circumference.

The above is the detailed introduction of Baidu Encyclopedia on Mawang.com regarding the calculation of baby weight during pregnancy. In short, after the mother enters the late stage of pregnancy, the doctor will judge the weight of the fetus based on the B-ultrasound results every time she has a prenatal check-up. During labor, it is even more necessary to estimate the weight of the fetus to determine whether natural birth is an option. Pregnant mothers can also calculate their baby’s weight according to the above formula!
