How does weight gain increase with gestation?
It must be said that approximately the first 2 months the weight of the pregnant woman increases insignificantly. This period is characterized by the active development and formation of the organs and systems of a future child. In this case, the embryo itself grows insignificantly. Also, it should be borne in mind that in the short term, women in the situation often face the phenomena of gestosis. Constant nausea and vomiting can adversely affect the weight of the future mother's body. As a result, for the first gestational trimester a woman adds only 1-2 kg.
However, already from the 2nd trimester the situation changes radically. So, for a week pregnant during this period can add on 270-300 on the average for all period of gestation (9 months) the future mum gets heavier on 12-14 kg.
It is worth noting that for long periods (from 39 weeks) every day the body weight can increase by 50-70 g. Thus, for a week the woman is gaining 350-400 g.
At each visit to the doctor during pregnancy, the values obtained are compared with the weight gain rate, which is indicated in the special table. If there is a significant discrepancy between this parameter, doctors give recommendations to a pregnant woman to follow a certain diet.
How can you calculate the weight of pregnancy?
As already mentioned above, physicians use a certain table to determine the rate of increase in body weight during child bearing. It allows you to accurately determine the correspondence of this parameter.
The same future mother can also approximately establish the norm of her weight during gestation. There is the following rule: weekly body weight of the pregnant woman should not increase by more than 22 g / 10 cm in height. For example, if the height of a woman is 175 cm, then it should not add more than 385 grams per week.
At that woman it is necessary to take into account the fact that each pregnancy has its own peculiarities. Therefore, do not panic if the weight is not normal. For any questions, it is best to consult a doctor who is monitoring gestation.
What factors can influence weight of a body during pregnancy?
The weight of the body during the period of bearing a child can be attributed to those parameters that are subject to significant influence from outside.
First and foremost, physicians, when evaluating it, regardless of the gestational age, pay attention to the woman's constitution. There is a kind of regularity: the smaller the weight before the onset of pregnancy, the more it increases immediately when the baby is born.
In addition to the above factor, the body weight is also affected by:
- presence / absence of toxicosis;
- Lifestyle;
- Amount of amniotic fluid;
- number of simultaneously bearing fruits.
If you specifically understand what actually causes weight gain during pregnancy, as can be seen from the table below, this is:
- Fetal body weight - on average 3.3 kg;
- The uterus together with surrounding amniotic fluid - 1,8 kg;
- placenta - 0.4 kg;
- volume of increased blood - 1.2 kg;
- mammary gland - 0,5 kg;
- mass of adipose tissue - 2.2 kg;
- The tissue fluid is 2.7 kg.
This is how the 12 kg are laid out. It should be said that for a multiple pregnancy, the body weight of a pregnant woman can increase by 14-16 kg.
