On scales... Ah!

So far as concerns a weight increase, many women with horror imagine terrible figures on a scale of scales. Whether the extra kilos gathered during pregnancy are so terrible? How many kilograms it is necessary to add for all pregnancy to be in shape after the delivery, to keep health?

Control and the account

At the first visit of a maternity welfare unit by the pregnant woman and registration the obstetrician - the gynecologist makes a number of manipulations which also weighing of future mother is among. And this compulsory procedure will repeat at each visit by the woman of the attending physician. The matter is that health of the child, health of future mother, and also character of a course of childbirth depends on the size of an increase of body weight.

can Control the weight between visits of the doctor independently. For this purpose it is necessary to meet several conditions allowing to avoid errors and inaccuracies of measurement:

needs to be weighed by

So you receive the most exact picture of your increase in weight. For convenience get a notebook or the file where you will bring indications of scales, And show records to the doctor at each visit as on reception at the doctor it is not possible to meet all conditions of weighing practically. At normally proceeding pregnancy (absence of hypostases, an excessive increase of weight or, on the contrary, its losses) to be weighed enough once a week - ten days. If the listed complications are observed, then the doctor will recommend to be weighed more often, and can sometimes be required to control the weight daily.

the Individual increase

the body weight Increase at different women during pregnancy can fluctuate in rather big limits, reaching 20 kg and more. But long ago it is known that both the excess increase in weight, and too small set of weight can be harmful both to mother, and to the kid as can lead to development of complications of pregnancy (diabetes of pregnant women, a large fruit, a preeklampsiya - the serious complication of pregnancy which is characterized by the increased arterial pressure, sharp decrease in function of kidneys, violation of brain blood circulation of the pregnant woman and t) .

Many experts hold the opinion that during pregnancy the average increase of body weight of the woman has to make 300 g a week the first 20 weeks of pregnancy, and in the second half of pregnancy (20 more weeks) - 400 - 450. Thus, the average woman during pregnancy has to gain 12 - 15 kg. But the body weight increase at each woman is individual and depends on the woman`s weight before pregnancy, to be exact on an index of body weight of future mother. Each woman can count the body weight index (BWI) itself - it is equal to the woman`s weight before pregnancy (in kilograms) divided into its growth (in meters) squared. Depending on initial IMT of future mother the doctor the obstetrician - the gynecologist conducting pregnancy commensurates the must increase with actual.

can be allocated to

Depending on the weight of future mother before pregnancy three subgroups of women: with the lowered, normal and increased body weight. IMT makes them respectively: 1 subgroup - less than 19,8; The 2nd subgroup - more than 19,8, but less than 26; The 3rd subgroup - IMT more than 26.

the body weight index (BWI) each woman can count

Thus, and the body weight increase during pregnancy in the allocated subgroups will be various. So, in 1 subgroup of women whose IMT less than 19,8, the recommended increase in weight makes from 12,5 to 18 kg. In subgroup of women, at whom IMT more than 19,8, but less than 26 (women of an average constitution), the body weight gain for all pregnancy makes from 11 to 16 kg, At IMT more than 26 (the 3rd subgroup of women with excess body weight before pregnancy), the average increase of weight for all pregnancy has to make 6,5 - 11,5 kg.


How many it is possible to add

In the table presented an average increase of weight (in kilograms) during pregnancy depending on the size IMT of the woman before pregnancy.

, From where kilograms?

Of what the general increase in weight during pregnancy consists?

In - the first, it is growth of the kid in mother`s womb. The table giving an idea of the approximate weight of the kid on different terms of pregnancy


In - the second is given below, it is a uterus which increases in sizes during all pregnancy. And at the end of pregnancy the mass of a uterus reaches on average 1000

Mammary glands. As a result of the physiological processes proceeding in an organism of the pregnant woman, beginning already with 3 - 4 - y weeks of pregnancy, future mother has a gradual increase of mass of mammary glands since 150 - 250 at the beginning of pregnancy till 400 - 500 in its end. Thus mammary glands prepare for the breastfeeding period.

Placenta. It is difficult to overestimate its role in pre-natal development of the kid therefore also its “weight“ is considerable - at the beginning of pregnancy the weight of a placenta exceeds fruit weight several times, by the end of pregnancy the mass of a placenta reaches 500 - 600.

Age of an embryo / fruit (in weeks) embryo / fruit Weight (in grams)
8 5
12 15
16 120
20 300
24 650
28 1200
32 1700
36 2600
40 3300

Amniotic waters (amniotic liquid) represent biologically active environment surrounding a fruit. Their volume depends on pregnancy term. They reach the maximum volume on 37 - 38 - y to week of pregnancy, averaging 1000 - 1500 ml, by the end of pregnancy the amount of amniotic waters can decrease and make a little by the time of childbirth about 800 ml that of course affects the general increase of weight the pregnant woman.

the Volume of the circulating blood at the pregnant woman increases for 30 - 50%, t, e. almost twice from initial level (before pregnancy) that averages an increase on 1200 - 1500 ml.

Considering also an increase of body weight of the woman, a liquid delay in the pregnant woman`s organism that is shown by some puffiness of legs at the end of pregnancy that everything together makes 3500 - 4000, we will get an average rise of body weight of the pregnant woman by the time of childbirth - 10 - 11 kg.

About all your fears, whether it be an excessive increase of body weight during pregnancy or, on the contrary, loss of kilograms for the small period of time (week - 10 days), it is necessary to tell your obstetrician - the gynecologist to establish the possible reasons of such changes and them to eliminate.

of Calorie for future mother

Since early terms of pregnancy and during its first half the power value of a diet for women with deficiency of body weight (the first of the subgroups described above) has to be 2100 - 2300 kcal and the diet has to include 90 - 100 g of protein, 55 - 65 g of fats and 290 - 320 of carbohydrates. If in food there are more calories, than it is necessary for an organism, then surplus collects in fatty deposits that eventually will turn back excess weight. Therefore the opinion on what thin women during pregnancy have to begin “is for two“, mistakenly. On the other hand, if the caloric content of food is lower than requirements of an organism, it starves and begins to fill energy due to use of own stocks, and not only fat, but also proteins which are so important for the normal course of pregnancy. That is why women with excess body weight before pregnancy should not limit very strictly themselves in food, and it is necessary to watch its nutritional value.

For pregnant women with a normal indicator of IMT the power value of a daily diet has to be 2400 - 2700 kcal. Content of proteins in such diet makes 110 g, fats - 75 g, carbohydrates - 350 g

For women with excess body weight before pregnancy (the 3rd subgroup) the power value of a daily diet has to be 2700 - 2900 kcal and the diet has to include 120 - 125 of proteins, 75 - 85 g of fats and 360 - 400 of carbohydrates. The balanced diet provides consumption of calories and nutrients (amino acids, vitamins, mineral substances) in that quantity in what they are necessary. It is important to eat so constantly as the organism is not able to reserve the majority of necessary substances for the future, so, their receipt has to be regular.

Thus, it is possible to formulate the main requirements imposed to food of future mother:

the food has to be balanced by

In the second half of pregnancy the need for proteins increases even more, and the daily power value of all diet beremen ache women from any subgroup has to was it is increased on average by 300 kcal.

, of course, needs to remind

I that pregnancy is not time for any diets. The child cannot correctly and fully develop, eating only mother`s “stocks“ - in them there is no that nutritional value and those minerals which are necessary for growth and development of the kid.
