How To Calculate The Correct Weight In Pregnancy

Weight in pregnancy is one of the relevant factors that are constantly monitored by the gynecologist during the various visits and checks.
It is normal to gain weight because it is a change in the woman’s body aimed at feeding the baby. In fact, most of the pounds gained during the nine months are due to:
- child (3.5 kilos)
- amniotic fluid (1 kilo)
- placenta (650 grams)
- increase in the size of the uterus (1 kilo)
- liquids that are retained (2-3 kilos)
So out of 12/16 kilos taken on average during the nine months, 3.5 is the weight of the baby and all the others are needed by the mother’s organism including an increase in the amount of blood in circulation, amniotic fluid, breast augmentation, placenta, stock of fats, etc …
During the first trimester, the fetus is still small and morning sickness may prevent weight gain. Most of the weight gain will occur during the second trimester. In the third quarter on average, he will put on half a kilo per week.
Generally, however, all gains of about 12 pounds for the entire pregnancy are considered to be on average.
Any advice on how to weigh yourself? Do not get too stressed and do not weigh yourself every day: it is enough to weigh yourself once a week, always doing it at the same time and without clothes.
Weight Gain In Pregnancy. How Much Weight To Take?

First of all, it is important to know that the vast majority of women lose the pounds accumulated during pregnancy within a year of giving birth. It is therefore very important to eat adequately, both to ensure the right supply of important nutrients to the maternal organism and the fetus (essential for its development) and to take healthy foods, which do not favor weight gain.
In short, you don’t have to eat for two, but you have to change your habits, abolishing the incorrect ones and promoting the healthiest and friendliest ones on the line.
As for the calorie intake, according to the recommendations, a daily calorie intake during pregnancy of 2,550 / 2,700 for almost all women should be followed, with an increase in the second and third trimesters.
Weight gain in pregnancy depends on two main factors – the pre-pregnancy BMI (Body Mass Index) and the type of pregnancy (single or twin) – and should be higher in underweight women, and lower in overweight women.
Some indications on what is the desired weight gain in pregnancy are based on the Body Mass Index.
- If you were underweight with a BMI below 18) in pregnancy you should gain between 2.5 and 18 c11.5 and 16 pounds;
- if you were overweight with a BMI between 25 and 29.9 an increase in pregnancy of 7 to 11.5 pounds is expected;
- in the case of obesity, with a BMI greater than 30, a weight gain between 5 and 9 kilos is desirable.
In multiple pregnancies, an average weight gain of between 11.5 – 16 kg is recommended.
