Normal weight gain during pregnancy by week
The fact that the weight of a pregnant woman is constantly increasing, there is nothing surprising. This process is natural and natural, therefore it refers to changes in a philosophical way. After all, it is not just extra pounds at the waist and buttocks, and, in the first place, growing: the uterus, the chest, the volume of amniotic fluid, the placenta and the baby itself. It is their share accounted for most of the weight gain. According to preliminary calculations, the kilograms collected are distributed as follows:
- 3-3,5 kg is a child;
- 0,6-0,7 kg - the placenta;
- 0,8 kg - amniotic fluid;
- 0,9 kg - the uterus;
- 0,4 kg - mammary glands;
- 2.4 kg - fluid retention and increased volume of circulating blood;
- 4 - fat deposits, formed as an energy reserve for further breastfeeding.
The result is 12-14 kg, but this is a fairly average value, which can fluctuate.
But, unfortunately, for many women, pregnancy becomes a kind of "green light" and they start eating in unlimited quantities and not always useful foods. Because of this, the numbers on the scales are rapidly increasing and Mom has health problems.
Others, on the contrary, realizing, than for their figure can turn back at times increased appetite, deliberately sit on a diet yet, being in position. Both extremes are extremely dangerous for the mother and her baby.
However, sometimes a fast or inadequate weight gain is a process that signals a malfunction in the body. Actually, therefore, gynecologists strongly recommend to keep a schedule of weight gain during pregnancy for weeks.
Norm and weight gain deviations by week during pregnancy
In order to calculate the allowable increase and estimate how well the pregnancy progresses, it is necessary to take into account such factors as the initial weight of a woman, her height, the length of her pregnancy and, of course, the number of embryos. There is a special table that specifies the norms for weight gain during pregnancy by week, depending on the body mass index (BMI) and the period. BMI calculation is extremely simple - this is the number obtained as a result of dividing the mass by the height in squares (the values are taken in kilograms and meters, respectively).
According to the table, women with obvious weight shortages (https: // / indeks-massy-tela-dlya-zhenshchin less than 18.5) can get more for the gestation period than those ladies who had this norm in norm or exceeded it. The addition of thin people can be about 18 kg, while the rest should be within the range of 9 to 14 kg.
The schedule of weight gain is significantly different for weeks when pregnancy is twins. Happy future mothers of two kids on average collect about 15-22 kg, while their weekly increase, starting from the second trimester should be about 0.7 kg.
So, with the norms of gaining weight of the pregnant woman for weeks, we figured out, now a couple of words about the reasons for too big or insufficient increase. Gynecologists reasonably recommend to future mothers not to throw a table of weight gain for pregnant women in the box, because excess kilograms can be a sign:
- diabetes mellitus;
- improper functioning of internal organs (especially the kidneys);
- polyhydramnios.
In turn, a small increase may indicate problems with the development of the fetus, or indicate a lack of water.
