Weighing for pregnant women becomes a procedure as necessary as, in fact, brushing your teeth in the morning. Pregnant woman is weighed by a doctor at each examination, she herself must watch her weight: every morning she should be on the scales, on an empty stomach and preferably in the same clothes.
In the first two months of pregnancy, the weight of a woman does not gain momentum. This is the stage when the body of a woman and the body of a baby "get used to" each other. Besides, often there is also a toxicosis, which contributes more to weight loss than to his set. Approximate weight "surcharge" of the first trimester - about one to two kilograms.
The pregnant woman begins to expand and expand in the second-third trimester. On average, the arrows of the scales each week stop at rates higher than the previous ones by 250-300 g.
Normally, for all nine months of pregnancy, a woman should gain 10-12 kg. According to doctors, from the week of the thirtieth the weight of the future mummy begins to increase by 50 grams per day. At 300-400 grams - a week. And no more than 2 kg - per month.
The gynecologist will most likely use a special table to determine the allowable weight gain. In addition, he watches and the scale of weight gain in the last 3 months of pregnancy.
As a rule, physicians consider something like this: no more than 22 grams for every 10 cm of growth weekly. That is, if the pregnant woman is 160 cm tall, then it can normally add 352 grams in weight. And if 180 cm, then 400 g.
But each case is profoundly individual, so all these indicators and are ideal, but rather conditional. The fact that the "pick up" the pregnant woman affects, first of all, her age: the older - the more inclined to fullness. Of course, the weight of the pregnant woman depends on whether she is inclined to fatness or thinness according to the constitution of her body. Of course, weight is also important, which was before pregnancy. By the way, the less she weighed before, the more she can weigh during pregnancy. This is because the body before the pregnancy could experience a "deficit" in the required kilograms. Besides, can not help but affect the loss in weight in the early toxicosis - the body will try to fill it. And, of course, if the baby is large - more than 4 kilograms - then the future mother has every right to put on weight well. Again, in the "ideal" cases, the kilograms of the pregnant woman (the norm of 10-12 kilograms) are distributed as follows: the baby weighs about 3300 g, the uterus and amniotic fluid - 900 g, the last - 400 g, the increase volume of circulating blood - 1200 g, mammary glands - 500 g, fat tissue - 2200 g, tissue fluid - 2700 g.
So these 12 kgs are formed. It is worth noting that it is very easy to lose weight after giving birth - it is reasonable and proper eating and doing special gymnastics.
To calculate how many kilograms you can afford during pregnancy, do not necessarily go to the doctor. Try to calculate your rate yourself. All you need to know for this is growth and initial weight. Together they turn into the BMI index. Calculate your BMI: BMI = weight (kg) / [height (m)] & sup2; .
According to the results of a woman with BMI & lt; 19, 8 - of a lean physique. If
BMI = 19, 8 - 26, 0, then this is a woman of average build, and if BMI & gt; 26, then this is already a category of women of fat physique.
