Pregnancy is a very exciting and responsible period in a woman’s life. After all, at this time she is responsible not only for herself, but also for her future baby. So many factors to consider! And many aspects regarding your own well-being and health need to be kept under control. Some of them, for example, the presence or absence of nausea, dizziness, abdominal pain, are extremely subjective. But, at the same time, there are also those that can be calculated objectively. This includes the weight of a pregnant woman by week - the calculator presented below can easily cope with this task using the data you entered. It will show what the body mass index is, and what the gain and, accordingly, weight should be by a certain week of pregnancy.

To get the result, fill in all fields

Now that we have ready-made numbers, they can be compared with the real state of affairs: is your weight normal? However, even knowing whether this indicator fits within the framework or not, it is necessary to understand why these standards are needed. We'll talk about this in the article.

Weight gain in pregnant women is normal

We all know that in the process of bearing a baby, body weight should increase. And this is natural, because a new organism grows inside a woman. However, the indicators change not only due to the weight of the fetus. What else does a woman add to her kilograms?

• Future baby (about 3.5 kg);
• growing uterus (approximately 1 kg);
• placenta (more than 600 g);
• amniotic fluid (almost 1 kg);
• fetal membranes, umbilical cord (250 g);
• added amount of blood (1.2 kg);
• breast growth (0.5 kg);
• adipose tissue (2.5 kg);
• intercellular fluid (2.7 kg).

The total is about 13 kg. An increase of 14 kg is considered the upper limit of normal. If a woman was underweight before pregnancy or is expecting twins, then you can safely add another 4-5 kg ​​to this figure.

As you know, pregnancy is “divided” into periods. So, relatively speaking, the unit by which the period is calculated is a week. All indicators that need to be monitored are tied to the 7th day. Why so, why not by a month? The fact is that in a week the fetus “overcomes” an entire stage of its development. Pregnant woman's weight by week - the calculator is also focused on this period of time. The weeks, in turn, are combined into trimesters. The first trimester occurs from 1 to 13 weeks, the second from 14 to 27, and the third from 28 to 42.

Calculation of weight during pregnancy is made taking into account that the fetus itself develops evenly and measuredly, but all other elements do not. This means that the increases will not be the same throughout the entire period of gestation, but will vary from trimester to trimester.

In the first 13 weeks, the number on the scale should not increase significantly. Every week, a woman with a normal BMI should gain an average of 125-150 g. But in the earliest stages, the increase can be only 50-80 g, and by the end of the 1st trimester - for example, 200 g. The most “fruitful” trimester is the second. Every week a woman can gain up to 400 g per week. Whereas in the third trimester you can gain a maximum of 1 kg per month. Thus, during the first half of the period of waiting for a child, the expectant mother will gain 40% of her final body weight, and during the second - 60%.

Underweight or weight loss in pregnant women

Sometimes when you try to check a pregnant woman’s weight by week, the calculator gives a figure that is higher than it actually is. In this case, we are talking about lack of body weight. Why might this be?

Firstly, there are physiological reasons. For example, a small fetus (if the father is 1.5 m tall and the mother is 1.40 m tall, you should not expect a giant child), accordingly, it weighs less than 3.5 kg. Blood volume may not increase as much; the placenta may also be lighter. Therefore, if the mother and baby feel well, the fetal development period according to ultrasound corresponds to the obstetric gestational age, and the child does not experience oxygen starvation, there is nothing to worry about. There is no reason to worry if a woman was overweight before she started expecting a child. She may not add pounds until the second half of the first trimester. Lack of weight gain and even some weight loss is even good in this situation.

But it happens that underweight is a sign of one or another pathology:

• severe gestosis in the early stages (in simple terms - toxicosis), when a woman often vomits, she cannot eat normally. In this case, we are even talking about sudden weight loss. This condition is dangerous both for the expectant mother and for her baby;
• malnutrition;
• frozen pregnancy.

The first and third points require hospitalization of the expectant mother in the obstetric department of early pathology. And if gestosis is relieved with progesterone and antiemetic drugs, as well as supportive treatment, then the frozen pregnancy, unfortunately, will have to be terminated. Malnutrition is corrected by diet.

Excess weight during pregnancy

But exceeding the indicators is always not very good. On the one hand, again, it can be caused by physiological reasons, for example, a large fetus (more than 4 kg). However, even in this case, the most a pregnant woman can afford is to gain 15 kg.

Among the pathological causes of excess weight:

1. Edema. This phenomenon develops quite often during the period of waiting for a child. It is associated with a slowdown in blood flow due to compression of many vessels by the growing uterus and increased load on the kidneys. However, they should not linger for long. If they are present, the obstetrician-gynecologist recommends mild preparations, often herbal teas, that will help get rid of them. But swelling in the third trimester is a reason to sound the alarm! Especially if they are combined with high blood pressure and the presence of protein in a urine test. These signs may be signals of a serious condition - preeclampsia. Immediate hospitalization and urgent delivery are required.
2. Problems with the thyroid gland. Hormonal imbalances often cause extra pounds. And while waiting for a child, the existing pathology can make itself felt. Diabetes mellitus is especially dangerous for pregnant women. Among other things, it “gives” extra pounds, not only due to the high weight of the fetus, but also due to an increase in adipose tissue, etc.
3. Overeating and sedentary lifestyle. It is believed that a pregnant woman should not deny herself food. Bananas with mayonnaise and potatoes at 3 am? Please! 5 kg of ice cream? Easily! But this is absolutely not true! And if the expectant mother really eats like this, then problems are possible. Her weight will differ significantly from the norms within which a pregnant woman’s weight should fit by week; the calculator will be “merciless.”

Gaining weight quickly is not beneficial. This can negatively affect the cardiovascular system and kidneys. It becomes difficult for a woman to breathe, she wants to move even less, and her mood worsens. And what could be more “unstable” than a pregnant, and even upset, woman?

The question of what is worse - too much or too little in mass is quite difficult to answer. But I'm inclined to think that it's still too much. This situation negatively affects all organs and systems of a woman, which are already subject to significant overload. During childbirth, there may be weakness in labor, often the date of delivery is delayed, and the fetus is born post-term.

Diet of a woman while expecting a child

In order for a pregnant woman to have a normal weight week by week, it is necessary to follow several nutritional rules:

In addition, of course, you need to give your body moderate physical activity. Of course, no one will put a “lady in position” on a treadmill. But you need to walk, move, dance, and do special gymnastics. And if you don’t do this, then the scale counter will inexorably creep up.

Thus, the body weight indicator by week is a very important figure throughout the entire period of waiting for the child. The calculator will help you calculate the weight of a pregnant woman by week, giving you a normal figure. Remember that the presence of a discrepancy may indicate not only individual characteristics, but also a pathological condition. Being underweight or overweight can cause complications during pregnancy, which is why it is so necessary to monitor the kilograms on the scale.

Weight during pregnancy is one of the most important issues worrying expectant mothers. Every time you step on the scale, you immediately want to know how much you have gained and whether your weight is normal for this stage of pregnancy. We invite you to calculate your weight using our calculator. Find out what weight is made up of during pregnancy and your normal approximate weight gain.

The average weight gain during pregnancy is 12 kg. An increase of 10 to 15 kg is considered normal, provided there is no pregnancy pathology (usually edema). During the first half of pregnancy, weight gain averages 4 kg.

A healthy pregnant woman gains on average 300 (+ - 30 g) weekly until the 20th week and 330 (+ - 40 g) from 21 to 30 weeks, 340 (+ - 30 g) before giving birth.

The weight is distributed as follows:

• Fruit weight - 3300 g
• Placenta - 650 g
• Amniotic fluid - 800 ml
• Uterus - 900 g
• Mammary glands -405 g
• Blood volume - 1250 ml
• Tissue fluid - 2500 ml

Weight gain occurs individually and primarily depends on the woman’s weight before pregnancy. To do this, you can rely on body mass index.

Body mass index is calculated according to the formula:

I = m⁄h2
m- body weight in kilograms
h- height in meters

A body mass index of 18.5-24.99 is considered normal. Indicators below and above these figures are considered underweight and overweight, respectively. With an initial lack of weight, weight gain can range from 13 to 18 kg. With initial excess weight, the increase can be from 9 to 11 kg, and with obesity up to 9 kg.

Weight gain during pregnancy is of great importance: women want to remain attractive and slim, and doctors monitor it because of the risk of complications and the development of pathologies. Intrauterine growth of the fetus is inevitably accompanied by weight gain, but it should not deviate significantly from the norm. This can be dangerous for both the woman and the child.

Why are these standards important for pregnancy?

According to recommendations for pregnant women of the American Institute of Health (used widely throughout the world), weight gain during pregnancy depends on the woman’s initial weight. To do this, you need to know your weight and height and calculate your body mass index (BMI). It is equal to the ratio of weight (kg) to height squared (m²). If a woman weighs 50 kg and is 1.60 m tall, then her BMI is: 50/(1.6)*2=19.5.

Allowable increase based on BMI:

• up to 19.5 kg/m² – from 12.5 to 18 kg;
• 19.8 – 26 kg/m² – from 11.5 to 16 kg;
• 26 – 29 kg/m² (excess body weight) – it is recommended to gain a maximum of 11.5 kg;
• 29 kg/m² or more (severe obesity) – no more than 6 kg.

It is necessary to adhere to the norm, since intensive recruitment can complicate the course of pregnancy, childbirth and the future life of the child. BMI is not calculated during pregnancy, as the indicator will be unreliable.

Causes of weight gain

During pregnancy, a woman gains weight not only because of the appearance and development of the child inside her, but also because of the changes that occur in her body's metabolism.

What causes physiological weight gain in a woman:

• fetal weight – from 2.5 to 4 kg, increases gradually throughout the entire period, but active growth begins from 26 weeks;
• uterus – reaches a weight of up to 1 kg;
• placenta (due to which the fetus lives and feeds) – 600 – 650 g;
• volume of amniotic fluid (necessary for intrauterine life) – 900 g;
• fetal membranes (amnion, smooth chorion, part of the decidua) and umbilical cord - an average of 300 g;
• breasts – increases by 0.5 kg;
• the volume of circulating blood through the vessels increases by 1 - 1.2 liters.

Due to the presence of physiological compensatory mechanisms, under the influence of hormones, a woman’s body prepares for childbirth, and therefore stores fluid. No more than 2400 g accumulates in adipose tissue, another 2500 - 2700 - in other types of tissues of organs and systems. If we sum up all the above factors, about 13 kg are added during 9 months of bearing a child. Scales for pregnant women are of particular value; they help control weight.

Marked weight gain may indicate the development of pathologies and disorders of lipid, protein, carbohydrate metabolism and water-salt balance. Often a sharp weight gain occurs due to edema, which is a sign of early or late gestosis (toxicosis).

Weight gain during pregnancy by week

Over 40 weeks, body weight is gained unevenly. It grows fastest at 2/3 (14 – 27 weeks). This is due to the fact that the metabolism of the expectant mother changes greatly. The placenta matures, intensive production of hormones begins, the volume of circulating blood changes, and the rate of deposition of “fat reserves” changes. The child has already formed the anlages of all organs, after which they begin to grow rapidly.

At the beginning and towards the end of pregnancy, weight gain is not so intense, because in the first 12 weeks the formation of internal organs occurs. In the later stages of pregnancy, functional maturation occurs and the fetus prepares for life outside the mother’s body (growth slows down).

The given values ​​are general for women with a normosthenic body type and a BMI of 21-25.5 kg/m². Weight gain by 21 weeks is a third of the total gain; after this period you need to weigh yourself every 7 days; if you suspect the development of edema, you should do this more often.

For those expecting twins

If a woman carries 2 fetuses at the same time, this entails weight gain. The total mass of the placenta increases, the volume of circulating blood increases, and all physiological aspects of weight gain undergo similar changes. Over the course of 40 weeks, both fetuses should grow synchronously. Their mass should be the same and increase equally over the weeks.

At birth, the weight of each of the twins is 500 - 800 g less than at the birth of one child.

Norms of weight gain for a woman based on BMI:

• from 18.5 to 24.9 – mother can gain from 17 to 25 kg;
• 25 – 29.9 – increase is limited to 14 – 23 kg;
• more than 30 – you can only add 11 – 19 kg.

How to calculate pregnancy weight by week

To do this, you need to know your initial weight (at the time of conception) and gestational age.

In the first 13 weeks, the increase should not be significant (5 - 10% of the total value). The second trimester is the most active in terms of weight growth. Up to 400 g per week (up to 45% of total weight gain). From the 26th week of pregnancy (in the 3rd trimester), weight gain slows down, and in each month you can gain no more than 1 kg, up to only 25% of the total value.

How to calculate a baby's weight during pregnancy

You can calculate the body weight of the fetus in later stages using the Jordania formula. To do this, you need to measure the circumference of the abdomen at the level of the navel, determine the height of the fundus of the uterus (the distance from the xiphoid process to the womb) and multiply the 2 resulting numbers. An interesting fact is that the height of the uterine fundus corresponds to the gestational age in weeks.

Calculation in 3 steps:

• abdominal circumference (AC) = 93 cm;
• the height of the uterus (HH) is 30 cm (that is, a period of 30 weeks);
• the estimated weight of the fetus is equal to OL * VDM = 93 * 30 = 2790 g.

Yakubova's formula is also applicable. You need to add the numbers for the abdominal circumference and the height of the uterus, then divide by 4 and multiply by 100.

• The patient's waist circumference is 93 cm;
• height of the uterine fundus – 30 cm;
• the estimated weight of the fetus is (93+30)/4*100=3075 g.

There are errors in calculations of this kind, so the most accurate and correct answer to the question about the child’s parameters can be obtained from the results of an ultrasound scan.

Losing weight during pregnancy

In addition to weight gain, there may be a decrease in body weight during pregnancy. In the first trimester, a woman often experiences severe stress. While she doesn't know she's pregnant, she's worried about her period being late. Toxicosis develops at 8–9 weeks. In this case, nausea, vomiting, and loss of appetite are observed. As a result, the pregnant woman loses a little weight.

In the 2nd trimester, pregnancy is relatively calm; for most, this period begins at 18 weeks. The woman does not feel any discomfort psycho-emotionally. Physiological processes stabilize, and the fetus begins to actively grow. Stopping weight gain or severe underweight may indicate malnutrition. Weight gain during pregnancy is a physiological process. Excess weight will quickly disappear in the postpartum period, and exhausting diets can lead to malnutrition (underdevelopment) of the fetus.

In the 3rd trimester, a few days before giving birth, a woman’s weight decreases slightly. The main reason for weight gain is edema, not an increase in adipose tissue. Since the hormonal background of the body changes before childbirth, the woman begins to lose excess fluid, urination becomes more frequent, and her weight decreases.

How to avoid gaining extra pounds during pregnancy

Solving the problem of gaining excess weight is not difficult. A woman must understand that the diet should be balanced and simple. Dishes should include natural products: meat, fish, vegetables, cereals, pasta. You can eat steamed food without a lot of oil. It is recommended to consume soups with low-fat broths, cereals, and vegetable salads. You don’t have to limit yourself to bread, but it is advisable to eat yesterday’s bread, not fresh.

You should drink water; homemade compotes, fruit drinks, yoghurts, and milk are useful. The drinking regime during pregnancy is determined by the gynecologist. Normally, a woman should consume no more than 1500 ml of fluid per day, including soups, tea and other drinks. Exceeding this indicator can provoke the appearance of edema. If the weight is added daily and begins to grow rapidly, then you need to consult a doctor. In order to detect pathological weight gain in time, weekly weighing data should be noted on the calendar.

In order not to gain excess weight, during pregnancy it is recommended to give up fast food, large amounts of sweets, alcohol, spicy, fatty foods, highly carbonated drinks, and strong coffee. Ready-made juices in packages are also not recommended, as they contain a large amount of sugar. Daily caloric intake for women is calculated individually, depending on the initial BMI, but not less than 1500 kcal. To comply with consumption standards, you can use a calorie calculator for pregnant women.

Consequences of deviations from the norm

It is necessary to comply with weight gain norms, since strong weight gain has negative consequences, just like pregnancy with obesity. Such women have a high risk of developing arterial hypertension, which may remain after childbirth. High blood pressure during pregnancy can lead to complications later in pregnancy. Among them:

• preeclampsia (edema, hypertension, massive protein excretion in the urine);
• eclampsia (development of seizures).

Another consequence of excessive gain is a violation of carbohydrate metabolism. For a pregnant woman, this is fraught with the development of gestational diabetes mellitus, mesocenosis (vaginal infection) often appears, and for the fetus - macrosomia (large fetus weighing more than 4.2 kg) and diabetic fetopathy. This newborn may have neurodevelopmental disorders or other developmental abnormalities. In some cases, there is evidence of pathology in dental deposits and cryptorchidism (undescended testicle into the scrotum) in boys.

Often, women with excess body weight gain are diagnosed with the development of a large fetus and polyhydramnios. This complicates the process of future childbirth. The likelihood of labor disruption increases. There may be the development of a clinically narrow pelvis. This is a condition when the fetus is too large for the existing size of the mother's pelvis. In this case, the question of surgical delivery (caesarean section) will already arise.

How is calculation done using an online calculator?

Calculating mass using an online calculator is simple. To do this, you need to know your weight before pregnancy, height, weight at the time of calculation, body mass index, and period in weeks. You need to enter data into the fields of the fetal weight calculator, and the result will appear on the screen.

A pregnant woman's weight gain is an individual indicator that is subject to monitoring by obstetricians. The weight of newborns is approximately the same, but during pregnancy, mothers gain a different number of kilograms. Some people easily fit into the norm and quickly lose weight in the postpartum period. Others gain excess weight and struggle with it for a long time. Some people even manage to lose weight. Why does this happen, and what to do if a woman’s weight gain goes against the norm?

Why does a pregnant woman's body weight increase during pregnancy?

Natural physiological changes lead to women gaining about 12-14 kg during pregnancy. The main share consists of the weight of the child (3.5 kg), placenta (1 kg), uterus with amniotic fluid (2 kg). Blood volume increases (1.5 kg) for normal transport of substances to organs. Interstitial fluid accumulates, its weight can reach 2.25 kg. The weight of the mammary glands approaches 1 kg.

At the same time, the female body stores up to 3 kg of fat, which is located in the abdomen, arms, and thighs. Why does lipid accumulation occur? This is facilitated by hormonal changes, the purpose of which is to protect the body from adverse factors. Adipose tissue protects the fetus and becomes a source of energy in the postpartum period. The increase in fat in the 1-2 trimesters and in the last stages of pregnancy occurs due to:

• increasing insulin levels in blood plasma;
• reducing tissue sensitivity to insulin;
• high levels of progesterone and estrogen;
• increase in the synthesis of adrenal hormones.

After childbirth, a significant part of the weight is lost. Losing the remaining kilograms is not always easy. Provided that a woman takes care of herself, she can lose weight to her prenatal weight in 3-6 months.

Child's weight and changes

The weight that the fetus gains must be monitored throughout pregnancy. This indicator gives the obstetrician information about the development of the baby and allows timely detection of deviations in the course of pregnancy.

The approximate body weight of the embryo and fetus is determined during an ultrasound from the 8th week, for which special formulas are used. They take into account the circumference of the head and abdomen of the fetus, the length of the femur, the period from conception, and the biparietal size. In the later stages, to determine the baby’s weight, the doctor only needs to know the circumference of the mother’s abdomen and the height of the uterine fundus.

In the first trimester, the baby's weekly weight gain is several grams; in the second trimester, the increase is hundreds of grams. From 11 to 17 weeks, the weight of the little person increases significantly (from 15 to 50 grams). After this period, the rate of growth slows down as the baby has to master skills such as moving his arms and legs. At 20 weeks, when most mothers have already felt the first movements, the baby’s body weight reaches 300-350 grams.

By week 25 this figure is 1200 grams. On average, before this period, every 7 days the baby gains 100-150 grams. By week 36 (the time when the newborn is fully viable), its weight reaches 2500-2600 grams. By the beginning of natural childbirth, the baby’s weight is 3300-3500 grams.

The following factors influence weight gain in newborns:

• Heredity (physique of parents). Children with broad-shouldered, stately mothers and fathers weigh more at birth than parents of average height and fragile build.
• Gender of the child. Typically, newborn boys weigh 200 grams more than girls.
• Repeated and multiple pregnancies. With each subsequent birth, the baby's weight in the womb increases. If twins are carried, the weight of each child at birth reaches 2800 g, and this is very difficult for the mother.
• Lifestyle of an expectant mother. If a pregnant woman does not limit herself in food, the baby’s birth weight will be higher than normal. Rich children are likely to develop obesity and diabetes in the future.
• Stressful situations, chronic illnesses of the mother. Stress can lead to both weight gain (“eating” problems) and weight loss. Chronic pathologies worsen during pregnancy, which interferes with the absorption of healthy calories and prevents weight gain.
• Toxicosis, smoking and alcoholism have a negative impact on well-being and interfere with normal pregnancy.

Norms for a woman's weight gain during pregnancy by week

An obstetrician will be able to calculate weight norms for the entire pregnancy. The increase in mass is uneven and individual in nature. Some people quickly gain weight almost from the moment of conception, while others can only gain the required amount of kilos after 21 weeks. Features of the increase:

• • The mother gains 40% of the total weight in the first half of pregnancy, the rest from the 20th week;
  • optimal growth in the first trimester is 200 grams weekly;
  • in the second trimester, appetite returns, and the pregnant woman’s weight grows quickly - about 350-400 grams per week;
  • in recent weeks, weight growth stops and amounts to almost 300 grams weekly;
  • 10 days before contractions, there is a slight decrease in the number of kilograms due to the removal of excess fluid (one of the precursors of labor).

The monthly increase rates are presented in the table:

Month of gestation	Weekly growth, g	Total increase, kg
1	0	0
2	+-200	-2-1
3	+-200	-2-2
4	+100-200	1-4
5	+100-200	2-5
7	+200-500	5-8
8	+300-500	7-11
9	+-300	8-15 (for multiple pregnancy - 11-19 kg)

How to calculate the optimal weight for different stages of pregnancy at home?

The expectant mother should make sure that there are scales (electronic, mechanical) in the house that show the correct data. Weighing is done as follows:

• step on the scale once a week, on an empty stomach, at the same time;
• weigh yourself after bowel movements, bladder;
• measure weight with or without clothes (for example, a T-shirt);
• record the measurement results in a calendar or draw up a special schedule.

In 2009, WHO developed a table of female weight gain during singleton pregnancy, which obstetricians are guided by:

Body mass index, kg/sq.m	Week of pregnancy, gain in kg
	2	8	12	16	20	24	28	30	36	40
Less than 19.8	0,5	1,6	2	3,2	5,4	7,7	9,8	10,2	13,6	15,2
19,8-26	0,5	1,2	1,45	2,3	1,4	6,4	8,2	9,1	11,8	13,6
26 or more	0,5	0,7	0,9	1,4	2,9	3,89	5,4	5,9	7,9	9,1

A simplified table view can be used for independent calculations:

This scheme can be taken as the basis for calculating the optimal rate of gain at 11, 16, 23, 27 and any other week of pregnancy. You can determine your body mass index by dividing your weight by your height in meters squared. For example, if before pregnancy the mother weighed 55 kg with a height of 170 cm, then the body mass index is calculated as follows: 55/(1.70x1.70)=21.45 kg/sq.m. Using the table, you can check what total increase in this case will be normal (11.5-16 kg). In the second trimester, for example, at week 27, an increase of 350-500 grams will be the norm.

What are the dangers of excessive weight gain?

Gaining excess weight (pathological gain) provokes a number of complications and negatively affects the well-being of the pregnant woman and the fetus. The heart, kidneys, and liver of the pregnant woman are under stress, shortness of breath and increased heart rate are observed.

Overstrain of all systems is due to the fact that the body needs to provide nutrition and oxygen not only to the fetus, but also to fat deposits.

Reasons for the strong increase in each trimester:

1. Excessively high-calorie diet. Excess of sweet, starchy, fatty and fried foods are harmful.
2. Fluid retention. Leads to edema and is dangerous for the kidneys.
3. Hypothyroidism. A lack of thyroid hormones leads to a slowdown in metabolic processes.

Excess weight during pregnancy is undesirable for the following reasons:

• high rate of weight gain is stress for the body, it is difficult for it to adapt to new conditions;
• joints are destroyed;
• back pain appears as a result of increased load;
• early aging of the placenta, dangerous for the fetus;
• increased risk of developing hemorrhoids and varicose veins;
• the risk of birth injuries, ruptures of the perineum and cervical canal during childbirth increases;
• Possible weak labor;
• the appearance of gestational diabetes, fetal hypoxia, edema, increased blood pressure, and gestosis is likely.

A large baby means a risk of difficult, protracted labor and caesarean section. Due to excess adipose tissue, the mother may have problems with lactation in the postpartum period. The reason is infiltration of the monoglandular lobules of the mammary glands.

Pathological weight loss

It happens that weight gain is slow, or a pregnant woman completely loses kilograms. This anomaly is considered by trimester:

• First trimester. Losses are associated with toxicosis, which forces one to refuse food and leads to dehydration.
• Second and third trimesters. Toxicosis is a less common concern, but the expectant mother may limit her diet for fear of gaining excess weight. Another reason for poor weight gain is chronic pathologies in a pregnant woman that interfere with the absorption of food.

Lack of nutritional intake affects the health of the fetus. The risk of early birth, miscarriage, and developmental delays in the baby increases. The doctor will help you adjust your diet and prevent pathological changes.

What to do if a pregnant woman’s weight does not meet the norm?

If excessive or slight weight gain is diagnosed, inpatient treatment is indicated. A gentle diet will be selected for the patient, taking into account the state of health and characteristics of pregnancy.

If you are overweight, you should temporarily limit high-calorie, salty, and fatty foods. Drinking regime is limited - up to 1.5 liters of water per day. You can take medications as prescribed by your doctor. Walks in the fresh air are recommended, and you should regularly do gymnastics to prepare for childbirth.

If you need to gain weight, doctors select a high-calorie diet and prescribe vitamins to stimulate appetite. When weight is not gained, treatment for relapses of chronic diseases and taking medications to alleviate toxicosis are possible.

Abnormal weight gain requires medical supervision. The following activities are carried out:

• prevention of miscarriage - taking progesterone up to 16 weeks;
• blood sugar control (before week 16), glucose tolerance test (after week 23);
• urinalysis to exclude pyelonephritis;
• prevention of exacerbations of hypertension and gestosis;
• fetal weight control.

How to prevent large weight gain during pregnancy?

How many kilograms a pregnant woman should gain depends on her weight before conception. Compliance with the following recommendations will allow you to control the increase:

• eating seasonal vegetables raw, stewed, baked;
• a balanced diet that contains proteins (lean meat, fish, dairy products);
• consumption of carbohydrates (cereals, durum wheat pasta), baking should be limited;
• fats should be consumed in portions, preference should be given to olive and sunflower oils;
• control the consumption of salt and sweets;
• daily caloric intake should be 300-450 kcal higher than what it was before pregnancy;
• The last meal time is 18:30, before going to bed at about 21:30 you can drink a fermented milk drink or eat light jelly.

The workload during pregnancy requires the mother to be attentive to her health. Compliance with the basics of proper nutrition and medical supervision will help you bear a healthy baby, and after childbirth you can easily return to the weight you had before conception.

During pregnancy, many women eat for two, which then negatively affects their figure. How to determine how much you can gain during pregnancy without gaining weight? The pregnancy weight gain calculator will help you with this. Thanks to a special program, you can calculate the weight that can be gained in a month or week.

It is worth noting that this figure is not the same for all women and varies widely between 10-18 kg. Girls who are underweight can afford to gain more than plump weights. This is due to the fact that the body is trying to compensate for the lack of body weight and make the fetus’s stay in the body more comfortable.

Distribution of weight gained during pregnancy:

If a woman wants to eat all the time, this does not mean that she will gain much weight. The pregnancy weight gain calculator by week will help you verify this. Usually, mothers carrying large babies suffer from excessive gluttony. But most often, extra pounds are deposited on the waist and hips. These are the ones you will have to fight with after childbirth.

It is worth noting that in the first trimester a woman usually does not gain weight, but rather loses weight. This is due to toxicosis in the first weeks of pregnancy. But after 3 months, the expectant mother even gains extra pounds. Usually the maximum weight during pregnancy is observed at 37 weeks. Just before giving birth, the body tries to get rid of excess fluid, and the woman loses 1-1.5 kg. This is quite normal, especially if you have kidney problems and swelling.

Why do you need to calculate weight during pregnancy?

This value allows you to keep yourself in shape and not gain too much. This doesn't mean you should starve yourself. But in some cases, gynecologists recommend limiting the consumption of sweets and starchy foods for 1-2 weeks. Doctors note that it is more difficult for overweight women to give birth and they feel contractions worse.

Weight fluctuates during pregnancy. Unfortunately, women carrying their second and third babies recover more. Fluctuations in weight gain are explained by hormonal imbalances and age.
