It should be noted that the weight of the body of the future mother should increase according to certain norms. According to them, and was drawn up, the so-called schedule for gaining weight during pregnancy, which clearly reflects at what period of bearing a baby, and how much, a woman should gain weight.
How does weight gain occur during pregnancy?
First of all, it should be noted that, despite the existing norms, deviations in one direction or the other are permissible, because each female organism is individual and intrauterine development of children also occurs with some differences.
When assessing the rate of weight gain during pregnancy, the doctor, first of all, takes into account the initial weight of the pregnant - normal or exceeds the norm.
So, proceeding from the given features, the future mum for 1 trimester of pregnancy should collect no more than 1500 g, or no more than 800 g if excess weight of the body was noted before pregnancy. If a woman for her height when registering for pregnancy had insufficient weight, then doctors allow for a set for the first trimester up to 2 kg.
In the 2nd and 3rd trimesters, the rate of weight gain by the expectant mother increases dramatically. So, according to the schedule of weight gain, during 14-28 weeks of pregnancy a woman should gain no more than 4200 g, i.ะต. for 300 g per week.
This phenomenon, like weight loss in late pregnancy, is normal. So individual future mothers note that for 9 months their body weight decreased by 1 kg.
How is the body weight of pregnant women evaluated?
The results obtained after weighing the pregnant woman, the doctors compare for compliance with their schedule of weight gain during pregnancy, which is calculated on a weekly basis. In this case, doctors use a special table, in which the rate of weight gain is indicated in accordance with the body mass index (BMI). This parameter is easy to calculate if the body weight of a person in kilograms is divided by its height in meters, squared.
