# Advice 1: How to know the weight of the unborn child

A natural way to give birth to a child with a big weight, very hard. Therefore, even before the birth of a baby expectant moms want to know weight. There are various methods of calculating the weightand, including using ultrasound and ultrasonographic studies. To the touch the doctor say about the weighte the future of the child only approximately.
You will need
• A late pregnancy, an inch and a calculator.
Instruction
1
With the help of ultrasound weight is determined by head circumference to an accuracy of 0.5 kg, but if the child is obscured, the specialist can make a mistake with the calculations. To calculate the weight of the future child is best at 32 weeks.
2
One of the most ofthe weight of thestandard methods is the method of Lebedev. To calculate the height of fundal multiplied by the circumference of the abdomen and the result is the approximate number of grams of fruit.
3
Many women believe that the size and weight of the future child can be compared with the size of the tummy, however, in nature there is no standard of the belly of a pregnant woman. It may be small, large, wide or sharp. Belly size depends on the weightand growth and breadth of the bones of the mother. The large weight of the fetus may be associated with a large weightof ω to the pregnancy and growth of the mother.
4
Determining the weight ofa future baby and is associated with the acquisition of first clothes, because buying a standard size you can make a mistake, because children are born with a weightω and 2.0 kg and 4.5 kg.
5
Another popular method of calculating the mass of a baby is a method Strelkovoi. For this weight a pregnant woman divided by the number of constants, which is taken into account weight. If a woman weightit 50 kg, then the constant is equal to 15, if weight 51 - 53 kg – constant equal to 16. Each 2 kg of additional weightand equal to one unit of the constant. Then the circumference of the tummy is multiplied by the height of the fundus, both amounts are added and divided by 2. The result is an accuracy of 200 gr.
6
38 weeks pregnant weight of baby can be determined at home using ordinary centimeter. Lying on the bed needed to find the upper edge of the pubic bone, to make every inch and stretch it on the middle line to the upper edge of the uterus. The result is multiplied by 100, what will be the approximate weightω of the child in grams.
7
If the kid is very large, it is necessary to discuss with your doctor caesarean section to read the literature about this operation and get psyched. A cesarean is also performed if the child is in the wrong position.
Note
If the location of the fetus wrong, and vyschityvanii weight of the unborn child can be greatly mistaken, therefore, to determine the weight, you need to check whether is in the womb a child.
The accuracy of calculating the estimated weight also depends on the period when it carried out its definition. It is worth considering that if the survey was conducted on 36 week of pregnancy, until birth, the baby can gain more than 0.5 kg.

# Advice 2 : How to determine the size of the fetus

Scientists abroad who have conducted the research of causality of child's growth, found that it primarily depends on the growth of the father, that is, the higher the father, the higher his child. However, an important factor is living conditions (nutrition, physical activity, presence of diseases).
You will need
• measuring tape;
• - ultra-sound study
Instruction
1
Genetic factor is one of the most important parameters determining the growth of the child. As a rule, growth in boys is due to the growth of the father or next of kin in the male line (uncles, grandparents) and the growth of girls is due to the growth of the mother and the relatives on the maternal line.
2
Contact your gynecologist. Parameters which can determine fetal growth: placental and obstetric estimates. If pregnancy occurs the disruption of the placenta, the fetus may develop hypoxia (oxygen starvation), leading to reduced growth and fruit development.
3
When visiting the gynecologist a pregnant woman using a measuring tape and make measurements of abdominal circumference and height of standing of bottom of uterus. Midwives in determining fruit size (large, small, normal) using several formulas, including: abdominal circumference (cm) multiplied by the height of standing of bottom of uterus (cm). However, the above formula is considered to be the easiest, but not the most accurate since it does not take into account the thickness of subcutaneous fat in pregnant women.
4
Contact the experts for carrying out an ultrasound. Using ultrasound to determine fetal size by measuring several parameters: kopchik-parietal (set to the date of the last menstrual period), bi-parietal (size between the right and left sides of the head), hip length (measurement of the longest bone of the body – the femur – reflects the length of the fruit, the length of the thigh, you can determine the duration of pregnancy), etc., if necessary, the doctor will conduct additional measurements.
Note
In addition to the genetic factors, on the size of the fetus affects the nutrition of the future mother, the presence of diabetes, the insufficient production of thyroid hormones, delayed pregnancy, fetoplacental insufficiency, syndrome of intrauterine delay development of the fetus, bad habits and chronic diseases of the mother and her age (if she is less than 15 years).
If a pregnant woman has a big belly, it is not necessary that she will have a big baby. It is possible that a large abdomen due to obesity or pregnant women have polyhydramnios.

# Advice 3 : How to know the size of the fetus

Determination of the size of the fetus during pregnancy – a necessary procedure performed by a gynecologist. This is done in order to evaluate the possibility of participation of the child in the process of labor.
You will need
• - consultation of the gynecologist;
• - Fetal ultrasound
Instruction
1
Contact your gynecologist. He will measure your belly from the pubic bone to the top part of the uterus. The resulting value is called the fundic size. This way you can accurately determine what will be the baby big or very small. Midwives, determining the size of the fetus (normal, large, small) use several formulas, one of which is abdominal circumference (in cm) is multiplied by the height of the uterus (in cm).
2
In addition, after you will be on the account in female consultation, your doctor will certainly check the condition of the placenta, which will also be judged on the size of the fetus. Due to improper activity of the placental unit may develop hypoxia, which leads to slow development and growth of the fetus and require medical intervention.
3
Pass ultrasound examination of the fetus, it much more accurately defines the size of the child. Scientists hundreds of times the ultrasound was conducted at different stages of pregnancy, the purpose of which were: the definition of the size of the fetus and calculating the estimated average size of baby at each week of pregnancy. The resulting measurement graphs of the average weight are considered the "gold standard", which determines a small child or large.
4
Consider the genetic factor. Usually, the growth of a boy driven by the growth of his father or close relatives (uncle, grandfather), on the growth of girls influences the growth of the mother and the nearest relatives on the maternal side.
5
Take into account that the growth and size of the fetus – not quite the same thing. To determine the size of a child can be after one ultrasound. The doctor will examine the fruit, will produce relevant measurements and compare their results with averages. To establish how the baby grows, you need to do ultrasound examination at least twice, with an interval of not less than two to three weeks.
Remember that each pregnancy is individual. And if the fetus has any specifics, that's not a reason to panic. Pass additional tests, refer to another specialist.

# Advice 4 : As an ultrasound to determine the child's weight

Ultrasound during pregnancy allows to determine whether the developing baby in the womb, what gender it is, and with the help of modern diagnostic devices you can even see how he smiles or frowns. In addition, using the ultrasound scanner it is possible to know the estimated weight of the child.
You will need
• Protocol ultrasound studies.
Instruction
1
The basic Protocol includes ultrasound study of the situation and presentation of the fetus, heart rate, location of the placenta, umbilical cord, internal organs, possible malformations. Made measurements of head, abdomen, chest, bones, heart, brain, and then the data is checked for compliance with the term of the pregnancy.
2
The body weight of the child is not required for diagnosis, but as a rule, the doctor calculates it and logs. This indicator is important in deciding prenatal care. In particular, if a woman has a narrow pelvis, and the baby is large, perhaps this fact will be regarded as an indication for caesarean section.
3
The software of ultrasound scanners contains various formulas of calculation of estimated weightand fetal (Hadlock, Merz, Shepard, Warsof, etc.), so the diagnosis is not difficult to calculate it. But if the doctor has not determined the body weight of the child, you can do it yourself.
4
Depending on the chosen formula, you will need the following measurements, which are necessarily conducted on each study during pregnancy:- biparietal head size (BPD – Biparietal Diameter); circumference of the head (HC – Head Circumference); the abdominal circumference (AC – Abdominal Circumference); length of femur (FL – Femur Length).
5
Calculate the weight of the baby on any of the formulas:- Hadlock: log(10)W=1,3596+0,0064(HC)+0,0424(AC)+0,174(FL)+0,00061(BPD)(AC)-0,00386(AC)(FL);- Merz: W=0,1(AC^3) or W=-3200,40479+157,07186(AC)+15,90391(BPD^2);- Shepard: log(10)W=-1,7492+0,166(BPD)+0,046(AC)-(2,646(AC+BPD))/1000;- Warsof: log(10)W=-1,599+0,144(BPD)+0,032(AC)-0,111(BPD^2(AC))/1000.Legend:^ - degree;log(10) logarithm;W – Weight – weight.
6
Keep in mind that any method of estimating the body mass of the fetus has some error. Considered the most accurate formula of Hadlock and Shepard, although they deviate in the range of 200-300 grams.
