The weight of the unborn child is an important criterion in order to assess whether the fetus is developing properly, fully and normally. It is the weight of the baby, which doctors combine with some other indicators, such as height, parameters of individual parts of the body, palpitations, which makes it possible to determine the current state of pregnancy in a timely manner. By the way the fetus gathers weight for weeks, the doctor is able to judge the development of the baby, as well as whether it is exposed to any pathogenic factors.
For example, if a fetus increases weight by week significantly behind the norm, then this can be a sign of starvation, both oxygen and food. Oxygen starvation can be in a child if a woman smokes or drinks during pregnancy. A food starvation can overtake the baby as a result of the shortage of nutrients needed crumbs. Lack of weight may also indicate a general slowdown in the development of the fetus and even a pregnancy fading .
The same applies to excessive weight, which occurs as a result of certain abnormalities or disorders in the development of the baby. Of course, every woman and her future child has an individual structure of the body, so you can not put everyone under one bar.
What should be the weight of the baby every week of pregnancy?
In order to somehow navigate during pregnancy and monitor the development of the baby, there are certain norms of the weight of the fetus for weeks. Usually, the total weight of the fetus is monitored by ultrasound examination, which is a reliable method with maximum accuracy. But ultrasound can be done only a few times during the entire period of pregnancy, so doctors determine the weight of the fetus "by eye", measuring the height of the standing of the uterus and measuring the total circumference of the abdomen.
In order not to get lost in guesswork, how much the baby should weigh at a certain period of pregnancy, there is a special table of the weight of the fetus for weeks:
Pregnancy, week | Fetal weight, g | Fetal length, mm | Pregnancy, week | Fetal weight, g | Fetal length, mm |
8 | 1 | 1.6 | 25 | 660 | 34.6 |
9 | 2 | 2.3 | 26th | 760 | 35.6 |
10 | 4 | 3.1 | 27th | 875 | 36.6 |
eleven | 7th | 4.1 | 28 | 1005 | 37.6 |
12 | 14 | 5.4 | 29 | 1153 | 38.6 |
13 | 23 | 7.4 | thirty | 1319 | 39.9 |
14 | 43 | 8.7 | 31 | 1502 | 41.1 |
15 | 70 | 10.1 | 32 | 1702 | 42.4 |
16 | 100 | 11.6 | 33 | 1918 | 43.7 |
17th | 140 | 13 | 34 | 2146 | 45 |
18 | 190 | 14.2 | 35 | 2383 | 46.2 |
19 | 240 | 15.3 | 36 | 2622 | 47.4 |
20 | 300 | 16.4 | 37 | 2859 | 48.6 |
21 | 360 | 26.7 | 38 | 3083 | 49.8 |
22 | 430 | 27.8 | 39 | 3288 | 50.7 |
23 | 501 | 28.9 | 40 | 3462 | 51.2 |
24 | 600 | thirty | 41 | 3597 | 51.7 |
But it is worth remembering that such indicators are not accurate, but only indicative. Therefore, when assessing the general state of the child, it is not worth making quick conclusions. In addition, such a survey should be done by a qualified specialist.
Most often the child at birth weighs from 3, 1 kg to 3, 6 kg. But there are kids and with a lot of weight, because the physiological structure of the child is affected by several factors:
- the sex of the child;
- nutrition, health status and the presence of harmful habits of a pregnant woman;
- possible pathologies during pregnancy;
- number of children in the womb.
Fetal weight after the twentieth week of pregnancy
Before the 20th week, the weight of the unborn child is not very large and is slowly accumulated. But already at 20 weeks the weight of the fruit is 300 grams, and at 30 weeks the baby weighs a whole kilogram more. This is ideal, but if such a good increase in weight is not observed, then it is worth paying special attention to this and finding out the reasons for the inadequate development of the baby. At the 38th week of pregnancy, the weight of the fetus should be at least or close to three kilograms, which indicates the normal development of the child and his preparedness for birth.
