Approximate weight gain during pregnancy. Pregnancy: weight gain per week. The rate of weight gain during pregnancy by week

13.08.2019

Excess weight has always been a cause for frustration for a woman, but with the onset of pregnancy, every kilogram gained becomes a joyful event. In the first weeks of pregnancy, a woman still does not notice changes in her body. Starting from the second trimester, the baby grows well, and the expectant mother rejoices as her tummy grows. Just during this period, you need to understand that it is easy to gain weight during pregnancy, it is important to know the norms so as not to harm yourself.

You can find out how much a pregnant woman recovered in a week or a month from a gynecologist. You need to visit a specialist once every 4 weeks, and starting from the 28th week of pregnancy, every 14 days. You can also control this process yourself. The obligatory morning ritual of every woman in an interesting position is weighing. You can get an accurate result if you stand on the scales every morning. The best time is before breakfast. Clothing should be as light as possible: a shirt for sleeping or a T-shirt with shorts. Immediately pick up a set of clothes so that it is convenient to weigh yourself in it for 9 months. This is the best way to control weight gain. And if you stand naked on the scales, then the result will be as accurate as possible.

Weight gain during pregnancy

Not every woman fully understands why extra pounds “come” during pregnancy. The bulk of the weight gain during pregnancy comes from the baby. Its weight on average ranges from 3 to 4-4.5 kg. Doctors add to this figure the same amount for body fat. The pregnant uterus also has a weight, on average - up to 2 kg along with amniotic fluid, plus the volume of blood in the body increases, and this is also about 2 kg. In addition, you need to take into account the weight of the placenta and breast. In general, it turns out another plus of 500 g and additional fluid in the body, about 1.5 to 3 kg. Based on the above, we can conclude that for 9 months of pregnancy a woman should gain approximately 14 kg. Do not worry that this is too much, after childbirth, the weight gradually returns to normal.

What can affect the weight of the expectant mother:

Completeness or a tendency to be overweight. If before pregnancy a woman was overweight, then during the bearing of a child, he will not go anywhere, but will only increase. Interestingly, thin women most often “eat up” kilograms, as the body begins to “catch up” with what was lost during pregnancy.
Even if, before conception, a woman went in for sports and controlled her weight, extra pounds will still come during the period of bearing a baby.
Height also affects weight gain. So, tall beauties can gain weight faster.
A woman is carrying a large baby and it is natural that her weight may be above the norm.
Edema and dropsy of pregnant women also add weight.
Increased appetite. If estrogen rises in the body, then the woman eats a lot and cannot stop. To avoid rapid weight gain, you need to get tested for hormones and pull yourself together.
A lot of amniotic fluid is also the cause of weight gain.
The age of the mother. The older the pregnant woman, the more she can put on weight, going beyond what is permitted.

Normal weight during pregnancy

According to generally accepted standards, while carrying a baby, a woman should gain an average of 9 to 14 kg. If twins are expected, then this figure increases, then the expectant mother can add about 16-21 kg. These are average indicators of the norm of weight gain, they can both decrease and increase, based on the individual characteristics of the body.

Pregnant weight by week:

first trimester of pregnancy. A woman practically does not gain weight, perhaps quite a bit, only 1-2 kg;
The second trimester is different from the first months of pregnancy. In these weeks, the expectant mother should gain only 1-1.5 kg per month;
approaching the beginning of the third trimester, weight gain is 400 g per week, which is approximately 50 g every day. It’s bad if a woman gains weight too quickly or vice versa, the scale arrow remains unchanged.

To understand how many kilograms you need to gain over the entire period of pregnancy, gynecologists use a special table that shows the approximate figures for weight gain during pregnancy for every 2 weeks.

It must be taken into account that there are no identical women, so the table has 3 columns with different body mass index: minimum, average and high. Low BMI is 19.8, average values: from 19.9 to 26.0, high - 26 units.

Let's take a closer look at the table:

in the first 2 weeks of pregnancy, a woman can gain no more than 500 g, regardless of BMI;
by the end of the 4th week, weight gain is 900 g, 700 or 500 g, respectively, depending on the body mass index;
at 6 weeks: 1.4 kg g, 1 kg, 600 g;
at 8 weeks - no more than 1.6 kg, 1.2 kg or 700 g;
at 10 weeks - 1.8 kg, 1.3 kg and 800 g with a BMI of 26;
by the end of the 12th week, a woman should add 2 kg, 1.5 kg or 900 g over the entire period;
at 14 weeks, weight gain is up to 2.7 kg, 1.9 kg or up to 1 kg;
at 16 weeks - weight gain can increase to 3.2 kg, 2.3 kg or 1.4 kg;
at 18 weeks, the weight of the expectant mother will increase by 4.5 kg, 3.6 kg or 2.3 kg;
at 20 weeks - 5.4 kg, 4.8 kg or 2.9 kg;
at 22 weeks - 6.8 kg, 5.7 kg, 3.4 kg;
at 24 weeks, a woman's weight increases by 7.7 kg, 6.4 kg or 3.9 kg;
at 28 weeks, weight gain is up to 9.8 kg, 8.2 kg or 5.4 kg;
at 30 weeks - 10.2 kg, 9.1 kg or 5.9 kg;
at 32 weeks, the rate of weight gain can be 12.5 kg, 10.9 kg or 7.3 kg;
at 34 weeks - 12.5, 10.9 or 7.3 kg;
at 36 weeks, a woman can gain no more than 1.1 kg, 900 g or 400 g in 2 weeks;
at 38 weeks, weight gain since conception is about 14.5 kg, 12.7 kg, or 8.6 kg, depending on the initial body mass index;
2 weeks before the upcoming birth (at 40 weeks), a woman can gain only 700 g, 900 or 500 g.

To find out your body mass index, you need to divide your weight in kilograms by your height squared. For example, a woman's weight before conception was 50 kg, height 1.75 cm. BMI is 16.33. This is a low indicator of a woman's body weight, so it is assumed that during pregnancy, the expectant mother can gain extra pounds.

You should not rely only on this table, each pregnancy is individual, a woman can immediately add 5-7 kg to the initial weight already in the first trimester of pregnancy, while others, on the contrary, systematically gain weight during pregnancy and only a few weeks before giving birth become very fat.

How to calculate pregnancy weight

From the moment of conception, the expectant mother is interested in everything, every detail in the development of her blood. Therefore, many mothers begin to keep a pregnancy diary, noting week by week how the baby develops. But what happens to the woman herself? After all, it also changes and in some way, begins to grow, systematically gaining weight. Therefore, in order to prevent deviations from the norm, gynecologists recommend that pregnant women record all the changes that occur to a woman. It is necessary to note in a notebook every day how much the expectant mother gained weight in order to calculate the figure for the week.

The process of increasing body weight is individual for each woman. Weight can increase in two pregnant women in completely different ways and it depends on many factors. You can find out an individual increase in kilograms on your own if you calculate the norms of weight gain during pregnancy, based on the data in the table or use the online calculator. You need to enter the gestational age (obstetric, from the start of the last menstrual period), weight before conception, and height. For example, a woman's weight before pregnancy was 50 kg, height 1.75 cm, gestational age 24 weeks. The calculator immediately calculates the body mass index. In this case, the woman has a low body weight, based on this, during pregnancy by the 24th week she should gain only 8.7 kg in weight and weigh almost 60 kg, or rather 58.7 kg. By the end of pregnancy, at the 40th week, the woman's weight should be 63.5 kg, weight gain for 9 months - 13.5 kg.

Overweight during pregnancy

Some pregnant women get so carried away with their interesting position that they forget that they need to stick to a healthy diet. Often during pregnancy, along with the allowable kilograms, a woman is gaining too much. As soon as the rate of weight gain accelerates, a woman begins to panic and may even restrict herself in food. This is just not necessary, because malnutrition can harm the baby. Go to a consultation with a specialist, spend more time in the fresh air, swimming and yoga for pregnant women will help stop the rapid weight gain.

How not to "eat" too much:

American scientists, conducting experiments, found such a pattern that those women who rapidly absorb “lazy” calories and gain fat mass give birth to children with normal weight. And those who gain "fat-free mass" can give birth to a large baby. Such a mass does not affect the volume and weight of a woman after childbirth.
The main rule while carrying a baby is that you can’t eat for two. In the first trimester, the child needs only 200 calories every day, and in the second and third trimester - 300 calories each, and they must be obtained from healthy foods: cereals, muesli, yogurt, boiled meat and fish, fresh vegetables and fruits. Starting in the second trimester of pregnancy, a woman may feel hungry more often than usual. The culprit is increased estrogen, this hormone literally forces the expectant mother to eat more food to satisfy her hunger. If such a condition does not lead to excessive fullness, then additional measures can not be taken.
Taboo on hunger. You can only limit yourself to the use of sweets and fats of animal origin. You can not refuse fresh fruits and vegetables, grains (complex carbohydrates). If a woman first eats a lot, and then arranges a day of hunger, then sharp jumps can lead to negative changes in the body, which can be dangerous for the child. If you are gaining extra pounds, you should not drastically slow down, it is better to gradually reduce the size of the portion you eat, give up sweet foods (buns, pastries, cakes, sweets).
Do not eat a lot of chocolates and chocolate, it is high in calories and fat, as well as caffeine. It hinders the absorption of folic acid, calcium and iron. In addition, it is worth refusing to drink strong coffee and black tea for all 9 months of pregnancy.
If you are tortured by toxicosis, you do not need to limit yourself or eat a lot at once. Keep portions and breaks between meals small, so the child can get more nutrients.
Slight swelling does not interfere with the normal course of pregnancy. When the kidneys are working well, the drinking regimen should not be limited. At least you need to drink up to 6 glasses of pure water per day. If you want to drink more, do not deny yourself this, since the amniotic fluid is able to be updated every 3 hours, so a pregnant woman simply needs water.

It is possible and necessary to bring the weight of a pregnant woman back to normal. For this, there are fasting days specially designed by nutritionists for pregnant women. If a woman is prone to rapid weight gain, leads a sedentary lifestyle, you can make a fasting day. It is allowed to "sit" on a diet only 2 times a month. Such days are especially relevant after feasts and holidays.

Unloading options:

on apples, you need to eat 1.5 kg of apples per day. Can be eaten fresh or baked in the oven;
on cottage cheese, eat 600 g, buy low-fat and do not add sugar. Better put half a teaspoon of honey;
fermented milk - you need to drink 1.5 kefir or yogurt per day. Drink little by little throughout the day;
fruit or vegetable - we eat 1.5 kg of fruits or vegetables per day (we give preference to pumpkin and zucchini);
fish or meat - per day you need to eat 500 g of boiled lean meat or fish.

During the fasting day, you need to drink at least 1.5 water, it is allowed to drink juices, tea and compote. The amount of ingredients indicated in the description of each fasting day should be divided into 6 servings.

How to return the form

Accept the fact that immediately after childbirth, the figure will not be exactly the same as before conception. It is normal if, after the birth of a child, a woman weighs not 56 kg, as before pregnancy, but a little more, let's say - 60 kg.

You can not immediately after the birth of the baby arrange starvation diets or eat nothing at all. Drink plenty of fluids, eat more healthy foods. If you want to dull your hunger a little, drink a glass of water before eating. Pour small portions, eat often.

If you wake up at night from hunger (especially after nightly breastfeeding), you can limit yourself to a glass of milk, yogurt or kefir.

Don't overwork! The body has not yet had time to recover after the birth of the crumbs, so you do not need to try to immediately return to its previous shape, squat and pump the press. If the birth was easy, then already 2 weeks after the birth of the baby, you can do light exercises: stretch, raise your legs, and also tilt your body (but not sharply) and just walk in the fresh air. Just the child will help to quickly return to shape - walk with a stroller on the street, take the baby in your arms, swing and just walk around the room, singing songs. Take your time and be patient, you will not even notice how the extra pounds disappear.

The weight of the fetus (child) during pregnancy

Determining the weight of the child during pregnancy is one of the important criteria for diagnosing its development. After all, it is this indicator that helps the doctor to understand whether the fetus is developing normally or there are any deviations. Determine the weight of the unborn child using ultrasound.

If the baby's weight is below or above the norm, this is an occasion to conduct a more detailed study in order to correct the management of pregnancy. After all, a shortage in the weight of the unborn child is a clear sign that the fetus is experiencing a lack of nutrition or oxygen. And also, unfortunately, developmental delays or fading.

The indicator of the weight of the child during pregnancy is above average - also a reason for the expectant mother to undergo a more detailed examination. Most likely, doctors will advise her to adjust her diet.

How does a baby gain weight during pregnancy? At the very beginning, the future baby weighs only 1.5 grams. The uterus increases in size, almost 500 times, and the baby grows. At first, he gains 10-60 grams per week, and closer to the end of pregnancy - 100-300 grams in the same time.

What is the danger of being overweight during pregnancy

Sometimes girls during pregnancy eat "for two" and, as a result, gain weight. Gynecologists unanimously repeat - excess weight is harmful, nutrition should be correct, and products should be healthy. However, with traditional weighing, kilograms grow. And this is not at all because the future baby is actively gaining weight. This is the extra weight of the mother, which is an unnecessary ballast, which, moreover, is also dangerous. So do not get better during pregnancy? And what is the danger of being overweight during pregnancy:

increases the likelihood of developing cardiovascular diseases;
there is a risk of violations and functions of the endocrine system;
there is a risk of varicose veins;
increases the likelihood of late toxicosis.

Being overweight during pregnancy can make childbirth difficult. For example, you have to do a caesarean section, since natural childbirth with excess body weight is dangerous for the life of mother and baby.

And extra weight during pregnancy is an annoying factor that prevents girls from quickly losing it after the birth of a baby.

How not to gain weight during pregnancy

While waiting for the baby, the girls “bloom” and look especially beautiful. Therefore, recommendations on how not to get better during pregnancy will be relevant. After all, you want to preserve beauty both at the beginning of pregnancy and at its later stages.

In fact, everything is simple - eat healthy foods, do not abuse baking, maintain water balance in the body, and often be in the fresh air. Let's talk about this in more detail...

Pregnant girls actually need more kilocalories. And if before 2000 kcal was enough for you to feel normal, in anticipation of the baby this amount will increase to 2800 kcal per day. But the products must be useful.

As soon as you feel hungry, snack on fruits, yogurt, nuts, dried fruits. Forget about fast food, sauces, sausages. They will not benefit you or your child.

The expectant mother should not eat "for two", even if she is actively persuaded. Through force, an eaten cutlet or sandwich will not bring benefits, but they will be deposited with excess fat.

Walking in the fresh air will help not get better during pregnancy. This is a charge of life-giving oxygen, and physical activity that will help keep the body in good shape.

The rate of weight gain during pregnancy by week

The fact that there is a norm of weight gain during pregnancy, the expectant mother learns almost at the first visit to the antenatal clinic. And in order for the weight to be normal, it is important to control it.

To determine whether the weight of the expectant mother is overweight, low or normal for her height, doctors use a special indicator - body mass index (BMI). And here is the formula: body mass index \u003d body weight in kg? /? Height in meters, squared.

Example for calculation: your height is 1.70 m, and your weight is 60 kg. We consider: BMI \u003d 60? /? 1.7 * 1.7 \u003d 20.7.

If the index is less than 18.5, the weight is considered below normal; index 18.5–25 is normal weight; 25-30 - overweight. And if the weight is more than 30 kg, this is already obesity.

When the weight is within the normal range and is gaining smoothly, there is no reason to worry. And if the expectant mother lost weight, stopped gaining weight, or it happens abruptly, you need to see a doctor.

weight gain chart during pregnancy

Expectant mothers are always wondering where extra pounds come from during pregnancy? Let's count together:

The result was an average weight gain of 12.5 kg. But since the pregnancy of each girl proceeds individually, then the weight indicators will be different. Some have more, some have less.

However, we must remember that excess weight during pregnancy, as well as its deficiency, is something that should be avoided.

diet during pregnancy for weight loss

The menu of the expectant mother should include products that are useful for her and the future crumbs. The amount of energy consumed during childbearing increases from the traditional 1800-2000 kcal to 2500-2800, so the need for food increases. But you need to eat right, and "not two." After all, it is known that many future mothers allow themselves what they limited themselves to in the “pre-pregnant” state. Hence the extra pounds.

How to eat so as not to gain weight during pregnancy? Let's count:

the need for protein food increases to 100 g per day. And this is about 100-150 g of veal or beef, or 150-200 g of fish, 100-150 g of low-fat cottage cheese; 50-70 g of cheese. The remaining 40% of the protein must be "get" by eating vegetables, fruits or cereals;
the amount of fat during pregnancy is an average of 80 g, of which 30% are vegetable. This is 25-30 grams of unrefined vegetable oil per day.
the need for carbohydrates during pregnancy increases to 400 g per day. To give them to the body, you need to eat fruits daily and 50 g of black and white bread.

What and how much should a future mother eat in order to follow a diet and provide the baby with iron, calcium and magnesium? We tell: 100 g of meat (iron), 100 g of cheese or 0.5 l of milk or kefir (calcium), 1 egg, 100 g of wholemeal bread (magnesium).

This approach to menu planning will help organize proper nutrition with excess weight, if the expectant mother has it.

Pregnancy: weight gain.

Pregnancy and weight, pregnancy weight gainWomen always watch their weight. But there comes a time when doctors begin to observe this indicator. And the aesthetic side of the issue does not bother them.

Until the 30th week of pregnancy, if everything goes well, the doctor examines the patient 2 times a month, and then once a week. Weighing becomes a mandatory procedure for each visit to the gynecologist and part of the "homework". It is better to perform it in the morning, on an empty stomach and in the same clothes, so that the results can be compared later.

Weight gain during pregnancy.

In the first 2 months of pregnancy, while the baby and mother are only adapting to mutual coexistence, a woman usually does not gain weight. In addition, at this time, she may be disturbed by toxicosis, which often leads to weight loss. So, in the 1st trimester of pregnancy, there is no intensive increase, the expectant mother usually gains 1-2 kg. The main events occur later, because the body weight of the expectant mother increases mainly in the 2nd half of pregnancy, when the weekly weight gain averages 250-300 g. If the process goes faster, this may mean the appearance of a problem - hidden, and then obvious edema (dropsy of pregnancy).

Let's look at the general rules that are accepted among doctors for calculating possible weight gain during pregnancy. So, for all 9 months of pregnancy, the expectant mother should gain 10-12 kg. It is believed that starting from 30 weeks of pregnancy, a woman's weight increases by about 50 g per day, by 300-400 g per week and no more than 2 kg per month.

To more accurately determine the allowable weight gain and take into account all additional circumstances, the doctor can use the table (see below). In addition, the doctor has at his disposal a scale of average physiological weight gain in the last 3 months of pregnancy. The calculation is as follows: weekly weight gain should not exceed 22 g for every 10 cm of growth. This means that a woman with a height of 150 cm can add 330 g per week, with a height of 160 cm - 352 g, and with a height of 180 cm - 400 g.

weight during pregnancy.

How many kilograms the expectant mother will recover during pregnancy depends on many reasons.

The first of these is age. The older the woman, the greater the tendency to be overweight.

Initial body weight (that is, before pregnancy). It is curious that the greater the weight deficit, the more kilograms the expectant mother has the right to add.

Weight loss due to early toxicosis. The fact is that, having survived the events of toxicosis, the body will try to compensate for the loss of kilograms.

features of the constitution. In this case, it is important whether a woman has a tendency to be overweight or thin.

Child size. If the patient is expected to have a large baby (more than 4000 g), then the placenta will probably be larger than average. Therefore, a woman during pregnancy has the right to gain more weight than if she expected the birth of a small child.

Increased appetite. It happens that during pregnancy, the expectant mother has an unbridled desire to eat and, if she cannot restrain it. There are problems with being overweight.

And now let's see what those same 10-12 kilograms of weight acquired by the expectant mother "leave" for. Indeed, if she recovered during pregnancy, as recommended, by 12 kg, she had a baby weighing 3 kg 300 g, then where are all the others? They are distributed like this:

* child - 3300g;
* uterus - 900 g;
* placenta - 400 g;
* amniotic fluid - 900 g;
* increase in the volume of circulating blood - 1200 g;
* mammary glands - 500 g;
* adipose tissue - 2200 g;
* tissue fluid - 2700 g.

Total: 12,100

And due to what can there be a "bust"? Our calculation shows that excessive weight gain depends on various circumstances: the weight of the child (large fetus), the amount of adipose tissue (weight gain with its initial deficiency), amniotic fluid (in case of polyhydramnios) and tissue fluid (if fluid is retained in the body) . If the first two circumstances are normal phenomena, then the last two are deviations from the norm, they require the attention of a doctor.

Pregnancy: the rate of weight gain.

Pregnancy and weight, pregnancy weight gain It happens that the expectant mother decides to follow a strict diet in order to ... not get better. Someone is afraid to spoil the figure, and someone (mostly women with a narrow pelvis) believe that food restrictions will lead to the birth of a small child. Both in the first and in the second case, these arguments are erroneous. If a woman gains 10-12 kg during pregnancy, then with the help of a reasonable diet and gymnastics, she will definitely regain her former size. Think, because, for example, ballerinas quickly return to shape after childbirth, although they usually add up to 18-20 kg during pregnancy!

You can calculate the allowable weight gain yourself. To do this, you need to know your height and initial weight, which then turns into a BMI (body mass index). Calculate your BMI: BMI = weight (kg) / [ height (m2) ]. Results:

BMI< 19,8 – женщины худощавого телосложения;

BMI \u003d 19.8 - 26.0 - women of average build;

BMI > 26 obese women.

Example:
Height - 1.60 cm, weight - 60 kg, BMI = 60 / (1.60) 2 = 2.30

It turns out that a woman has an average physique, which means that at a period of 30 weeks the optimal weight gain for her will be 9.1 kg, and at a period of 40 weeks - 13.6 kg.
weight gain table by

Every woman needs to monitor her weight, because a beautiful figure is an integral part of an attractive feminine image. But one day there comes a moment when doctors begin to monitor the weight of a woman. And this does not mean at all that she is sick - no, she is just expecting a baby!

Weighing is a mandatory procedure at every visit to the gynecologist. In addition, in order to control weight, the woman herself needs to weigh herself daily. Moreover, this must be done at the same time - in the morning on an empty stomach, and certainly in the same clothes.

How does weight gain occur during pregnancy

The first two months of pregnancy, as a rule, pass without weight gain, because the woman's body is only adapting to its new state. In addition, many expectant mothers during this period suffer from severe toxicosis, and this, on the contrary, can lead to weight loss.

So that in the first trimester, the increase averages no more than 1-2 kg(an exception may be women who have previously followed a strict diet, or athletes who are forced to significantly lighten their training program due to pregnancy).

More active weight gain occurs in the second trimester of pregnancy. According to the norms, during this period, a woman should gain 250–300 g of weight weekly. If the body weight of a pregnant woman increases faster, this may be a sign of a serious problem - dropsy of pregnancy, which is accompanied by edema .

In accordance with this scale, the average weight gain during the week should be no more than 22 g per 10 cm of growth. Thus, with a growth of 150 cm per week, a woman should gain no more than 330 g, with a height of 180 cm - up to 400 g.

Weight of a woman during pregnancy

How many kilograms the body weight of the expectant mother will increase is influenced by many factors.

These include:

Age. The older a woman is, the more inclined she is to be overweight.
Initial weight(meaning body weight before pregnancy). The greater was the deficit of body weight before pregnancy, the higher the chances of gaining extra pounds.
Was there early toxicosis. If a woman had severe toxicosis in the first months of pregnancy, then she could lose several kilograms, which then the body begins to replenish at an accelerated pace.
Features of the constitution. Do not forget that some women are prone to thinness, while others are prone to fullness.
Fetal weight. The size and weight of the placenta depends on the weight of the fetus. That is, a woman who is expecting a large child or twins gains more weight than one whose fetus is small.
increased appetite. Some pregnant women put on a lot of weight just because they cannot contain the increased appetite.

Let's look at a separate example of how the kilograms gained by a pregnant woman are distributed in the body. So, with an increase of 12 kg, they are distributed as follows:

weight of the child - 3 300 g;
the weight uterus - 900 g;
placenta weight - 400 g;
the weight amniotic fluid - 900 g;
weight of the mammary glands - 500 g;
weight gain due to increased blood volume circulating in the body - 1,200 g;
adipose tissue mass - 2,200 g;
mass of tissue fluid - 2,700 g.
And the total amount is 12.1 kg.

What is the normal weight gain for a pregnant woman?

Some pregnant women try diet to limit the increase in their weight: someone is afraid of gaining too much weight, others - to give birth to a large child. That is why it is so important to know what is the rate of weight gain for you personally - this will help you avoid problems and not make mistakes.

Weight during pregnancy by week

We calculate the allowable weight gain on our own, using Body mass index (BMI index). To do this, you need to know your initial weight and height. Let's use the formula BMI = weight in kilograms / (height in meters * height in meters). According to the calculations, it turns out that in overweight women this indicator is > 26, in women of average build - 19.8–26.0, and in thin women - \< 19,8.

And now, having calculated the BMI, consider the optimal weight gain by week of pregnancy:

Gestational age	Weight gain in kg with BMI > 26	Weight gain in kg at BMI 19.8-26.0	Weight gain in kg at BMI

The greatest fear of a woman during pregnancy is naturally associated with the developmental norms of the baby. But a gradually increasing arrow of the scales can cause panic. Hormonal changes change taste habits and desires, portion control is lost, the expectant mother begins to gain weight. Not to go beyond the norm in order to endure and give birth to a baby on your own is the task of each. It will also help a woman after childbirth to go through the recovery period faster and return to shape before conception.

The table of the rate of weight gain during pregnancy by week will allow you to control the weight gain during the entire period of gestation. With sharp jumps, it is necessary to adjust the diet and daily routine to restore performance.

How does weight gain happen?

Natural physiological processes lead to an increase in the body weight of a pregnant woman by an average of 10-12 kg. This figure falls already at 36-38 weeks, by the time of delivery. The main part is the weight of the baby (3-4 kg), as well as the uterus, which grows proportionally as the child develops (2 kg along with amniotic fluid). The volume of blood also increases significantly; 1.5-1.8 kg will be required to transport all the nutrients and oxygen. More fluid accumulates in the body, fluctuations occur in the range from 1.5 to 2.5 kg.

Excess weight affects not only the mother, the child by the time of birth can be very large, and the process of childbirth is complicated by sizes over 4 kg. It provokes gained kilograms and late toxicosis, dangerous by an increase in pressure, and the appearance of deviations. Weight loss is also undesirable, especially in the second and third trimester.

Correct weight measurement

Control is necessarily carried out by a gynecologist, in a consultation before an appointment, the nurse weighs the expectant mother. If there is a scale at home, and the woman keeps track of the weighted grams on her own, it is worth remembering the simple rules:

the optimal time will be morning, immediately upon awakening, after breakfast, and also during the day, the weight may vary - increasing by 500-700 grams;
for the weighing process, choose permanent clothes, the consultation does not always take into account the factor of heavy warm sweaters, massive shoes, so the numbers of home and medical weighing may diverge;
it is worth writing down the data obtained in a notebook, if necessary, showing them to the doctor to track possible drastic changes.

Set norms

Average data allow you to control the performance of both the pregnant woman and the child. If one fetus is gestated, the optimal weight gain is from 8 to 16 kg. Accordingly, with twins, the indicators increase from 16 to 22 kg. These are indicative data, they can vary both up and down, depending on the physiological characteristics of the woman.

The rate of weight gain by trimester:

in the first trimester, all the internal organs and systems of the embryo are laid, so the increase is minimal - no more than 2 kg, if toxicosis is observed during this period, on the contrary, you can lose weight dramatically, after all the kilograms can be replenished;
in the second trimester + 1 kg per month is a good indicator, the pregnant woman and her doctor can be satisfied with this result, the figure should not exceed 330 grams per week;
in the third trimester, the child grows intensively, along with it the uterus, place, and the amount of amniotic fluid increase in size, so an increase of 1.6-2.3 per month is considered normal, any sudden jumps are undesirable, the baby grows gradually, and the rapidly gained kilograms will be deposited on mother's figure in the form of adipose tissue.

In other cases, a woman can gain a norm of 10-14 kg at the beginning, and then keep this figure until the very birth. Or vice versa - an increase in mass occurs a few weeks before childbirth. Such physiological features cannot indicate developmental abnormalities if other analyzes and studies correspond to the norm for this period of pregnancy.

Weekly weight gain

Analysis of indicators helps to control regime moments and nutrition for the normal course of pregnancy. There is a set of kilograms unevenly, until 12-14 weeks the figure can remain without apology. The most intensive growth occurs from 15 to 34 weeks, and in the period immediately before childbirth, the expectant mother may lose some weight.

Weekly weight gain during pregnancy depends on the woman's initial body mass index. Calculating it is quite simple: the weight must be divided by the height squared. Indicators from 19 to 25 are considered normal, less - a lack of kilograms, more - fullness, as well as different degrees of obesity. The less the expectant mother weighed before conception, the more she gains all 9 months (14-16 kg). If a woman had excess volumes before pregnancy, then her recruitment rate should not exceed 8-11 kg, and with obesity - up to 6 kg, with the obligatory observance of a diet.

Causes of weight change

It is impossible to define averages that apply to all women. There are factors that provoke excess weight gain:

the initial weight of the pregnant woman, the smaller it is, the faster it is replenished with the gained kilograms for the entire gestation period;
the genetic tendency to be overweight makes itself felt, even with a balanced diet and physical activity;
growth also matters, the higher it is, the more proportionately more will be recruited;
if the child is large, naturally, the expectant mother will eat more, and the weight will increase rapidly in the third trimester;
swelling and dropsy leads to fluid retention in the body, due to which the arrow of the scales will increase already at the end of the first trimester;
a change in the hormonal background leads to an uncontrollable feeling of hunger and satiety, if the efforts of the will do not help limit the number of servings, the extra 5-10 kg are guaranteed;
increased amount of amniotic fluid, polyhydramnios often leads to overweight, the condition requires constant medical supervision;
in women after 30-35 years, the metabolic rate decreases, a natural weight gain occurs.

Toxicosis of the first and last trimester can lead to a sharp decrease. The greatest risks for the fetus are the deterioration of the mother's condition in recent weeks. It is important to constantly monitor all biochemical parameters.

Danger of deviance

Deterioration in the quality of life, shortness of breath, palpitations, limitation of physical activity are not the only problems that appear along with volumes. Both for the baby and for his mother, gaining extra pounds is associated with health risks:

varicose veins, deterioration of the cardiovascular system, which means a lack of nutrients for the child;
the load on the spinal column and pressure on all internal organs increase;
the difficulty of diagnosing the condition of the fetus during pregnancy;
development of hypertension and diabetes;
planned or urgent caesarean section;
premature birth or gestation of the fetus;
excretory system infections;
possible complications of the birth process, both natural and during caesarean;
delayed fetal development;
violation of proportions between the head and the pelvis;
the child's tendency to develop obesity, diabetes mellitus in the future;
neurological disorders, episyndrome.

How much a pregnant woman should put on weight depends on her initial weight. To control the normal increase, you should follow the basic recommendations:

learn to eat right, the diet should consist of a variety of high-quality and fresh foods, proteins are required in the form of lean meat - rabbit, turkey, chicken, fish, cottage cheese, cheese, yogurt and whole milk;
vegetables and herbs will help stabilize the weight, preference should also be given to traditional fruits and berries;
fats should be present in the form of vegetable oils, seeds, nuts, it is important to control the portion amount;
carbohydrates useful for mother and child are found in cereals and whole grain bread, and it is better to refuse flour products with excess weight;
salt restriction will help to avoid puffiness, it is also worth controlling the consumption of sugar, store-bought juices and sweets;
a set of physical exercises for pregnant women will allow you to prepare for the process of childbirth and not gain excess weight, and will also speed up the subsequent recovery period.

A pregnant woman should not starve and diet. Reducing the volume of portions and fractional nutrition will stabilize the weight to normal.
