However, the weight of the fetus did not increase as expected by the pregnant mother, so where did the weight of the pregnant mother increase during pregnancy?
Overall distribution of weight gain during pregnancy
The weight gain of pregnant mothers mainly comes from four categories:
During the whole pregnancy, the pregnant woman * * * increased by 2 1.72-29.46kg, so after giving birth, the mother will find that if the baby's weight+amniotic fluid volume+placenta weight is removed, the mother will only reduce11.32-15 kg.
This is because most of the weight of the human body, such as body fluids, blood flow, uterus and so on. It still remains in pregnant women and will gradually fade after delivery, but pregnant women's own fat needs postpartum exercise to lose weight.
How much weight gain during pregnancy is normal?
The normal range of pregnant mothers' weight gain during pregnancy is 10- 12.5 kg, but due to the influence of pregnant women's pre-pregnancy weight, the weight gain of pregnant women will vary from person to person.
Thin mothers gain 25-36 kg during pregnancy, moderate mothers gain 23-32 kg during pregnancy and overweight mothers gain 14-23 kg during pregnancy.
The thinner the mother before pregnancy needs to gain more weight, and the fatter the mother before pregnancy needs to gain less weight.
This is also a matter of considering fetal nutrient absorption. If the mother is too fat and eats too much nutrition, then the fetus absorbs too much nutrition, and it is easy to give birth to a giant child.
If the mother is too thin and eats too little nutrition, it will lead to fetal growth retardation and even affect the development of fetal brain.
Therefore, mothers must control their weight during pregnancy. It is best to keep the weight consistent with the gestational age. Really not, nor too small for the gestational age. Some mothers lack nutrition, which leads to the need for nutritional injections to promote fetal development. Of course, if your mother is overweight, you should not only control your diet, but also increase your exercise.
After pregnancy, the weight will increase and the waist will become thicker, but the situation of each pregnant mother is different. Some will gain too much weight and gain a lot of fat on themselves. Some gain weight just right, and the fetus is not meat. Some babies are a little small because of poor appetite and too little weight gain. We can look at the growth of standards.
Standard weight gain
Weight gain during the whole pregnancy 10- 15 kg is ideal. Thin pregnant mothers can grow much longer, while overweight mothers can control their weight properly and grow less. Most pregnant mothers of twins are 16- 18 kg. So where did all this weight come from?
Weight distribution
In addition to fetal weight, pregnancy weight also has its own weight gain.
Fetal weight: 3 kg -4 kg
Placental weight: 0.7kg
Amniotic fluid weight: 1 kg
Maternal fat: 2.5 kg
Blood increase: 1.5kg.
Water retention: 2.5 kg
Breast: 0.5 kg
Uterus: 1 kg
* * * meter: 12.7- 13.7 kg.
Law of weight gain
Weight gain is not linear, some stages grow fast, and some stages grow slowly.
Early pregnancy: Due to severe early pregnancy reaction and loss of appetite, weight gain will be very small, some will not even increase, and some will lose 5 kilograms.
Second trimester: The uterus, placenta and fetus increase obviously, and then the weight begins to increase rapidly. Be careful not to be anemic or overeating, which will lead to gestational diabetes.
Third trimester: With the growth of the fetus, the required energy will increase, the appetite of pregnant mothers will also increase, and the weight will gain the fastest. Pay attention to calcium and iron supplementation.
In short, most of the weight during pregnancy is on oneself, the average fetal weight is only 3-4 kg, and the combined weight of placenta and amniotic fluid is 1.7 kg. So be sure to control your weight and prevent it from being difficult to lose weight later!
How much weight gain is appropriate during pregnancy?
At the beginning of pregnancy, many pregnant mothers have poor appetite and little weight gain, and some even lose weight because of morning sickness, which is normal.
By the second trimester, the morning sickness reaction disappeared, the pregnant mother's appetite became better, and her weight began to rise. Most of the weight gain comes from amniotic fluid and fat.
The third trimester is the peak of fetal weight gain, and this period is also the fastest time for pregnant mothers to gain weight.
During the whole pregnancy, the ideal weight gain is 12 kg, but this is only the average. Actually, the weight gain of pregnant mothers is different.
There is a standard for gaining weight during pregnancy for your reference:
Body mass index = pre-pregnancy weight (kg)/pre-pregnancy height (m) squared.
For example, my weight before pregnancy is 46 kg, my height 1.6m, my body mass index = 46/(1.6 *1.6) =17.97, and my standard weight gain during pregnancy is12.5-/kloc.
You can also calculate your body mass index, and then judge how much weight you gain during pregnancy is more appropriate.
Where did you gain weight during pregnancy?
The weight gained during the whole pregnancy, except the weight of the fetus, amniotic fluid and placenta, all grew on the Ma Bao.
The fetus weighs 3-4 kilograms,
The increased blood volume is 1.5 kg,
The added liquid is 1.5 kg,
Breast weight gain 1 kg,
Placenta weight 0.5- 1 kg,
The uterus increased by 65438±0kg,
Amniotic fluid weight 1 kg,
The increased fat is 2.5-3.5 kg.
* * * Weight gain:12-14.5kg.
In short, most of the weight gained during pregnancy is on the pregnant mother herself, so pregnant mothers should exercise more, control their weight and avoid the difficulty of losing weight after delivery while ensuring nutrition during pregnancy.
Generally speaking, the standard weight of pregnant mothers is about 20-30 kg, while most of the babies born to pregnant mothers are only about 5-8 kg. Many pregnant mothers also say that drinking water in the third trimester will make you fat, so where are the other weights besides the baby's weight?
Weight gain can be roughly divided into two aspects.
The following two aspects are the natural needs of pregnancy. If the pregnant mother weighs more than 30 kg during pregnancy, it means that you are overweight during pregnancy and your body has increased unnecessary pregnancy fat.
Below I made two charts to show the categories and proportions of weight gain during pregnancy more intuitively:
Weight gain category of pregnant women
Weight gain rate of pregnant women
(The above data are all estimates. )
The weight gain of pregnant women is a very important thing for the whole pregnancy, which directly affects the health of pregnant mothers and babies. It is an important thing that pregnant women can't ignore. Ensuring a reasonable diet and moderate exercise throughout pregnancy is the main measure to ensure that the weight is in a suitable range.
Of course, the recommended weight gain is only a guiding principle. Even if the weight is slightly lower or slightly higher than the average, a healthy and lovely baby can be born.
Good luck ~
Generally, pregnant mothers begin to gain weight obviously from April, and the weight gain is about 10- 15kg when they are about to give birth. Some pregnant mothers have a good appetite, or some have no weight control, and some have gained 25kg, just like a big fat man! But the child born will not be too heavy, concentrated in 3-4kg, so where is the other weight?
According to the normal weight gain of about 13kg, the increased weight includes
Blood: 1.5 kg
Tissue fluid: 1.5 kg
Fat: 3.5kg
Breast: 1kg
Uterus: 1kg
Placenta: 0.5- 1kg
Amniotic fluid: 1kg
Fetal weight: 3-4 kg
What is the weight of pregnant mothers with different weights during pregnancy?
Before this, pregnant mothers need to know a term called "body mass index", that is, body mass index, which is an index to measure whether the weight of pregnant mothers is standard or not, and can also provide guidance for pregnant mothers to gain weight during pregnancy.
Body mass index (BMI) = weight (kg)/square of height (m? )
If the body mass index is lower than 18.5, it means that the pregnant mother is underweight;
If the body mass index is between 18.5-24.9, explain the weight standard of pregnant mother;
If the body mass index is between 25 and 29.9, it means that the pregnant mother is overweight;
If the body mass index exceeds 30, it means that the pregnant mother is obese.
For pregnant mothers with different weights, the specific weight gain suggestions are shown in the table below:
For example:
Ms. Zhang weighed 45kg when she was pregnant, and her height was 160cm. Her body mass index =45/( 1.6)? = 17.58, the weight is light, so it is recommended to gain weight during pregnancy. 12.5- 18kg.
The amount of weight gain in different pregnancy months is different.
The weight gain of pregnant mothers in the first trimester is relatively slow, generally not exceeding 1kg, and some pregnant mothers may lose weight due to morning sickness and other reasons; The weight gain of pregnant mothers in the second trimester can reach 5-6 kg; In the third trimester, the baby's development speed is accelerated, and the pregnant mother's weight gain is also relatively fast, about 0.5kg per week. The above is the general situation. Every pregnant mother's personal physique is different, and her weight gain will be different.
The importance of weight control during pregnancy
If the pregnant mother gains weight too slowly during pregnancy, the baby may be stunted; If pregnant mothers gain too much weight, it may lead to macrosomia or gestational diabetes.
That's my answer, I hope I can help you!
Hello, let me answer this question.
Many mothers find it strange that children are usually 6-8 kg when they are born, and they will grow more than 20 kg when they are pregnant for the first time. Do you have to be an aunt after giving birth?
But some mothers give birth from waist to waist, hip to hip (also a little bigger), and only have a few laps of breast enhancement. Where did all this weight go?
Let's take a look at where the weight during pregnancy mainly grows.
According to the calculation of pregnant women with normal weight before pregnancy, we suggest that the best weight gain during the whole pregnancy is about 25 kg.
Mainly divided into three aspects:
1, the weight of fetus and nutritious fetus (about 12 kg)
Fetus is 6-8 kg, uterus+placenta+amniotic fluid is about 5 kg.
2. In order to compensate the fetal mother's body (about 5 kg)
Mother's blood volume increased by 3 kg, and body fluid increased by 2 kg.
Why is it easy to lack iron during pregnancy, and the symptoms of iron deficiency anemia will appear if there is more iron in the blood without a corresponding increase?
Why is it easy to edema during pregnancy? Look for the toilet every half hour. In addition to uterine compression, there is an increase in body fluids.
3. Weight for breast-feeding after birth (about 8 kg)
Breast weight increased by about 2 kg, body fat and muscle weight increased by about 6 kg.
Generally, the weight of the first item disappears after we give birth to the child, and the weight of the second item will be slowly digested when we are confinement. The weight of the third item is consumed by breastfeeding.
Therefore, the best way to lose weight after delivery is to prevent excessive intake of fat and sugar, and transfer the fat from the mother to the baby through breastfeeding, so that the baby will be white and fat, and the mother will be slim.
Generally, pregnant mommy will gain weight about 12kg during the whole pregnancy (ideal).
One third of them grow on the stomach (amniotic fluid, fetus, placenta, etc.). ), two-thirds grow on the pregnant mother herself (breasts, fat, etc.). ).
In the early pregnancy (0~3 months), pregnant mothers gain weight slowly, and some may only gain one or two kilograms. There are also some pregnant mothers who may lose weight because of morning sickness.
In the second trimester (4~7 months), the weight of pregnant mommy will usher in a period of rapid growth. During this period, the weight gain of pregnant mommy is mainly in amniotic fluid and fat.
In the third trimester (8~ 10 months), the pregnant mommy's belly is getting bigger and bigger, so the weight is mainly on the baby. Approaching the expected date of delivery, the baby weighs about 2.5~4 kg.
Generally speaking, the weight that really grows on the fetus during pregnancy is only about 4 kilograms at most, and about 3 kilograms of placenta and amniotic fluid are removed, and the rest grows on the pregnant mommy herself.
Therefore, pregnant mommy must control her weight during pregnancy. Too much weight gain during pregnancy is not good for the baby and pregnant mommy.
For a nanny with a standard figure, the weight will increase by about 12.5kg during the whole pregnancy, which means a full 25 kg. Where did the weight of 25 Jin grow?
Weight gain during pregnancy mainly comes from uterus and contents, breast, increased blood volume, interstitial fluid (edema), maternal fat and protein storage.
Where did you gain weight during pregnancy?
Where did you gain weight during pregnancy? I was particularly curious before Martin, especially a colleague who was very thin during pregnancy. The whole person is thin and has a small stomach. The weight before pregnancy is more than 80 kilograms, and the weight in the third trimester is close to 1 10. I really don't know where those 30 kilograms gained weight. Later, my colleague gave birth to a baby and weighed less than 90 kg the next day after delivery, only to know that they were all fat to the baby and amniotic fluid placenta.
Look at the chart. Before delivery, the blood flow of standard weight pregnant women increased by 1.36- 1.82kg, the breast increased by 0.45- 1.36kg, the placenta increased by 0.68kg, the amniotic fluid increased by 0.9kg and the uterus increased by 0.9-1.36kg..
Therefore, it is normal for pregnant women with standard weight to gain weight 1 1- 15kg during pregnancy. If you weigh too much, it is estimated that either the fetus is too big or the pregnant woman has too much fat and is somewhat obese. If it is too much below this weight, the fetus may be smaller. It is suggested to pay attention to prenatal examination and increase nutritional intake.
In addition, usually after delivery, the maternal weight will drop by 5- 10kg immediately, or even more, which is caused by the discharge of fetus, placenta, amniotic fluid and blood.
Pregnant, gaining weight, where is the meat? The newborn is only six or seven pounds? Then let's use science to calculate.
Scientific computing
The normal weight gain during the whole pregnancy is 10~ 15kg, in which the fetal weight is about 3~4kg, the maternal weight is about 3kg, the rest tissue fluid is 1.5kg, the uterus and breast are about 1.5kg, and the blood is about1.5kg.
From this point of view, most of the weight gain during pregnancy is inevitable for fetal development, rather than simple weight and fat gain, but most of them are in pregnant mothers, and postpartum slimming is a difficult problem.
Among them, the fastest weight gain is in the second trimester, that is, pregnancy 16-28 weeks. With the advancement of gestational age, there is another peak after 36 weeks of pregnancy, and the fetus develops rapidly.
Therefore, it is necessary to do a good job in weight management during pregnancy and try not to increase it by more than 15KG. Postpartum recovery is more troublesome.
