Fetal weight by week - table

One of the main criteria for assessing the development of the fetus in the tummy of a future mother is its weight. Shortage may indicate that the child does not receive enough oxygen or nutrition. In the worst case, a significant lag in the weight of the future baby from the norm at the appropriate time of pregnancy can even speak of his fading.

Excess of the norm also indicates the presence of any violations. In addition, too large a fetus may be an indication for the delivery of a pregnant woman, through a caesarean section.

Norms of weight of the fetus for weeks are shown in a special table. Depending on the period of pregnancy, it is possible to see the estimated mass of the future baby. However, these values ​​are too approximate, and one can not ignore the complex of parents and other factors affecting the development of the child in the womb.

In this article, we will tell you how to calculate the weight of a fetus, and what is an increase in weeks of pregnancy is normal.

Fetal weight gain by week

Track the weight of the baby's future until 7-8 weeks of pregnancy is almost impossible, because it is less than 1 gram. Starting from this period, the weight of the fetus increases very rapidly - with each week of expectation of the child, its value doubles.

After the 14th week of pregnancy, the formation of crumbs organs slows down, and the brain begins to develop rapidly. The future baby learns to wiggle his fingers and limbs, blink. In this regard, weight gain decreases, and the increase becomes less noticeable. From 28-30 weeks, the crumb again begins to significantly increase in weight, preparing for the birth. A normal increase in this period can be 200-300 grams per week.

How to calculate the weight of the fruit for weeks?

After 32 weeks of waiting for the child to determine its weight, you can multiply the value of the circumference of the belly of a pregnant woman by the height of the bottom of the uterus. Both values ​​are measured in centimeters. This method is very approximate, and its error is about 200 grams. In addition, these calculations can greatly affect the amount of amniotic fluid, the physique of the future mother, as well as the location of the baby in the uterus.

The only accurate method that allows you to determine the weight of the fetus for weeks is ultrasound diagnosis. At the same time, modern devices allow you to immediately evaluate all the parameters of the future baby, including weight, and their correspondence to the period of pregnancy. If minor deviations in the development of the fetus are detected, the doctor will most likely offer you to perform the diagnosis again after 1-2 weeks, and in case of confirmation - will prescribe the necessary treatment.
