To determine the correctness of the course of pregnancy, a very important point is the weight of the fetus and the process of its recruitment in the womb. This criterion is important because it can show the features of fetal development and the presence or absence of any abnormalities in it. For example, too little fetal weight may indicate insufficient nutrition or oxygen, if, say, a woman smokes or consumes alcohol. In severe cases, the absence of a set in the weight of the fetus indicates the fading of its development. Excessive weight is also a pathology and indicates abnormalities occurring in the mother's womb.
So, how does the child gain weight in the womb?
There are certain norms and criteria that help to track the correctness and timeliness of the weight of the fetus.
At the beginning of pregnancy, the embryo barely weighs anything. And only from the 8th week of pregnancy you can track its weight. At week 8 the weight of the fetus is 1 gram, the length is 1.6 cm. By 10 weeks, the fruit should weigh about 4 grams and have a length of 3.1 cm. Starting from the 15th week of pregnancy, the fetus is gaining weight in a strengthened mode: at week 16 it weighs 100 grams, length is 11.6 cm. At 20 weeks, the weight of the unborn child should reach 300 grams and a length of 25.6 cm. By the 25th week, the weight increases to 660 grams and up to 34.6 cm in length. The 28th week is marked by a new digit of 1000 grams and 37.6 cm of fetal length. At 31 weeks, the weight reaches 1500 grams and 41.1 cm. At 34 weeks, the weight of the fetus passes over 2 kg, more precisely - 2150 grams and 45 cm. The weight of the unborn child at 40 weeks is about 3460 grams, and the length is 51 2 see
These figures are rather arbitrary, but the dynamics of fetal growth throughout the entire pregnancy is visible. As the development progresses, the baby gradually increases the intensity of his growth. By the end of pregnancy, the fetus is gaining almost 300 per week, whereas in early terms, the intensity of weight gain is small and amounts to 10-60 grams per week.
To track the weight of the fetus and its increase is helped by ultrasound. Ultrasound is a fairly reliable and accurate way of determining the growth of the fetus. And in the last trimester of pregnancy, an experienced doctor already determines the weight of a child by eye. For this, he measures the circumference of the abdomen, as well as the height of the standing of the uterine fundus. But for a full guarantee, yet many appoint an additional ultra-sound study. The method of ultrasound is applied at 6-8 weeks, before it is usually not used - the fetus is still undeveloped.
Summing up, I want to emphasize that the main thing in fetal development and weight gain is not the quantity of grams, but the presence of positive dynamics. After all, the excessive weight of the fetus, as already mentioned, can also lead to various disorders. Girls are born usually slightly lighter than boys - only a few hundred grams. But in fact, everything happens in different ways, and the run-up in weight sometimes reaches several kilograms.
