Abdominal size during pregnancy rule for weeks

Any mom is interested in tracking how the abdominal dimensions are changed for weeks pregnancy. But it is not just curious, but also need. Specialists systematically conduct an outdoor obstetric study. After 20 weeks of pregnancy, they begin to measure the size of the abdomen, but only a mother can fix it for weeks. This is due to the fact that planned women's consultations are much less common. The doctor needs to know the abdominal circle (coolant) and the height of the uterus standing (VDSM). These data allow us to judge the full development of the fetus and immediately detect any deviations from the norms.

How the belly grows during pregnancy

As a rule, the stomach begins to grow with. But he still remains calming. Consider that much depends on the physique of the woman itself. Almost in all cases, from 16 it is, how the tummy grows in women with thin physique. Already from 5 months of gestational period, you can rejoice as a confidently grows the tummy during pregnancy. The future mother begins to update the wardrobe, as the old clothes in the waist begins to argue. You can not allow the feeling of compresses. It disrupts blood circulation and fraught with unpleasant consequences. As the tummy grows, pregnant should choose free and comfortable clothing. From 20 weeks, the specialist includes an external obstetric examination. The tummy becomes clearly visible without clothes.

What affects the abdomen during pregnancy?

You could have noticed that two pregnant women on the same period may be different stomach size. Therefore, it is difficult to talk about the norms of volume. The growth rate of the tummy, as well as its difference between the form may depend on several factors.

The height of the bottom of the uterus for weeks of pregnancy

Measuring the base height of the bottom of the uterus begin to measure from 20 weeks of pregnancy. This is done with each visit to the specialist. The obtained indicators are compared with the standard gravelogram.

abdominal circle for weeks of pregnancy

When you need to find out the intended power of the fetus, the specialist can measure the abdominal circle on different weeks of pregnancy. To do this, you will need only a centimeter tape. It must be placed around the tummy pregnant at the navel level. Calculations of the alleged weight of the fetus are carried out according to the following formula: coolant must be multiplied by VMM. By measuring the abdomen circle for weeks, allow you to determine the akuster the term of pregnancy, identify a violation of the fat exchange, a multi-way or a small breeder.

If an ordinary person ask a question - what is the pregnant woman differ from the rest of the representatives of the beautiful half of humanity, the very first answer will be words about the changed circumference of the abdomen. Of course, after 13-14 weeks, the appearance of a tummy can see the appearance of a tummy, and as the pregnancy is progressed, the abdomen will only increase, reaching its maximum size for approximately 10-14 days before delivery.

Such accurate measurements are important, of course, for doctors-gynecologists, because according to their dynamics, even without using modern diagnostic equipment, an experienced doctor can identify the very first signs of possible disadvantaged

During pregnancy, the dimensions of the fruits (uterus) increase many times, and its increase occurs not only due to the growth of the fetus, but also due to the increase in the placenta and the volume of the spindle fluid and the fetal shells.

If in the first 12 weeks of pregnancy, the uterus remains behind the bones of the pelvis and is not palpable even during the examination in the doctor of the gynecologist, then by the end of the first trimester of pregnancy, its bottom rises above the Lonnoy Jim.

From now on, during each visit to the female consultation, the doctor will measure the height of the bottom of the uterus and the abdominal circumference of the future mommy - for this, even in modern conditions, an ordinary centimeter tape is used.

Focusing on the obtained indicators and comparing them with the average norms, the gynecologist can not only determine the estimated period of pregnancy and even determine the alleged mass of the fetus.

To do this, it is enough to multiply the height of the standing bottom of the uterus and the circumference of the abdomen - even in the last period of pregnancy, the error usually does not exceed 100-150 grams.

Certainly, the concept of the norm in the event of a conversation about the size of the abdomen circumference is quite relative - the doctor assesses not only the result of the measurement, but also the constitution of its patient.

Let's immediately say that the belly looks like and grows during pregnancy, depends on the set of reasons: the buildings of a woman, the structure of the pelvis, the muscles, the growth of the uterus and the child, the number of ammunition. Therefore, someone has a stomach grows faster, someone is slower, in some moms he is big, others can have almost imperceptible. But still some common patterns of growth and size of the abdomen during pregnancy are.

As a rule, in the early grades of pregnancy, the stomach in size does not increase or increases quite slightly. This is due to the fact that the uterus is still very small and places in the small basin it takes a little. So, for example, by the end of the 4th week, the uterus achieves only the size of the chicken egg, it increases to the size of the goose, but the most important thing is at that time it does not reach the Lonatic Jim (located at the bottom of the abdomen). That is why in the early last time there is no increase in the abdomen. And only after the 12th week (end of the first trimester of pregnancy) the bottom of the uterus begins to rise above the Lona.

At this time, the child sharply gaining growth and weight, and the uterus is also growing rapidly. That is why on the period of 12-16 weeks attentive mom will see that the belly has become noticeable. True, the surrounding will pay attention to the new position of the woman about the 20s week, especially if it will wear tight things.

Approximately with a trimester of pregnancy During each inspection, an obstetrician gynecologist determines the height of the bottom of the uterus and measures the abdominal circle at the navel level. Why does the doctor so carefully monitors the increase in the mother's tummy? The fact is that this is the easiest way to control the growth and development of the future kid.

By the way, earlier in the form of the abdomen often tried to determine the sex of the child. It was believed that the round belly foreshadows the girl, and the elongated, oblong, "sharp" boy. However, these predictions have not always come true, since the form and size of the belly depend at all of the floor of the child.

The size of the abdomen during pregnancy largely depends on the individual characteristics of the body of the woman. For some future mothers, the tummy manifests itself extremely late, while others notice the manifestations of the rounds of forms in the initial timing - 15-17 weeks.

An increase in the tummy during the period of napping due to the systematic growth of the fetus in the womb and additions. Minor changes in the size of the abdomen can be remarkable for the mommy itself already with, while others can guess about the position only from 20 weeks. At this moment, the stomach becomes rather notable, but still women with large forms can hide it much longer.

What affects the size of the abdomen?

Specialists in the course of measurements are guided by generally accepted standards, but at the same time take into account the fact that the indicators may differ significantly in each case.

Mommies prone to completeness, roundness may not be noticeable until the very moment of childbirth, while girls with a narrow pelvis and brittle physique are faced with a change in the volume of belly at the very beginning of the second trimester. Abdominal volumes with multiple pregnancy increase rather quickly, therefore an interesting position can be noticeable to those surrounding much earlier.

Belly sizes can increase non-scenario, but jumps. Experts begin to track the dynamics of the addition of centimeters in the abdomen circumference not immediately, but, as a rule, from 17-20 weeks of pregnancy.

The greatest circumference of the abdomen - on. At this point, all the most important stages of the formation of the fetus are completed, and the bottom of the uterus reaches the peak. Do not panic if the tummy has become less than 38 weeks, most likely the baby took another position, because he is preparing for an emergency meeting with mom. Immediately before the date of birth, the standing height of the bottom of the uterus is reduced and "abdominal omission" occurs.

How to measure the belly?

Women during pregnancy are particularly sensitive, and it is natural. The reason for anxiety can be a deviation for a couple of centimeters. Of course, in this case you need to calm down. Because all the indicators are individual.

If the pregnancy proceeds without complications, the abdomen of the abdomen depends on the growth of the fetus. The gynecologist begins to measure the stomach in a pregnant woman from the beginning of the second half of pregnancy, from 20 weeks. The measurement results will help identify various pathologies in the development of the fetus.

In the early periods of pregnancy, the development of ectopic pregnancy can be suspected of changes in the growth of belly. In the later dates, too small an increase in the circumference of a pregnant tummy can say about the development of the hypotrophy of the fetus or the occurrence of a lowland. Too big belly during pregnancy may indicate multi-coded pregnancy or that the baby grows very large in volume. In any case, the formulation of a diagnosis can be confirmed by ultrasound.

Women's doctor when measuring the growth of belly uses two parameters: the abdominal circle and the height of the uterus. And the height of the bottom of the uterus clearly suggests how many weeks of your pregnancy.

How is the volume of belly measurement correctly during pregnancy?

Starting from the 20th week of pregnancy, the tummy grow noticeably. And at each visit, the doctor measures its volume and height of the bottom of the uterus, and also defines its shape. It is very important for determining the term of pregnancy, the alleged mass of the fetus, identifying a violation of fat metabolism, multi-way and multiploiting.

centimeter tape measure the greatest circumference of the abdomen at the navel level. By the 30-32 week, about 85 cm, at the end of pregnancy it is equal to 90-100 cm. The abdominal circle can tell us a lot! Too small in the scope of belly for a certain period may indicate ectopic pregnancy, hypotrophy of the fetus, underdeveloped pregnancy, lowland. A number of these deviations provoke the development of inflammatory diseases of the genital organs of women, gestosis, fetoplacentage insufficiency. Increased in size, it can be with multi-way, placental tissue tumors, or with multiple pregnancy (several kids).

The consequence of the multi-way is an involuntary miscarriage, delay in the development of the fetus, premature genera, fetoplacentage failure. However, this is just a subjective parameter, which is individual for each woman, and to confirm the pathology it is necessary to undergo a number of other studies (ultrasound, laboratory tests).

Table of abdominal volumes during pregnancy and the standing height of the bottom of the uterus

As a rule, doctors use standard dimensional numbers. At the same time, the data obtained by the doctor during measurements may differ from the standards. And this is due to a number of reasons. In the list of factors that direct influence on the abdomen, the following items:

Doctors are usually starting to follow the growth dynamics not immediately. In the first trimester there is no need to measure volumes - because the fruit is still formed, it will actively grow with the second trimester. Then will start measurements. Doctors note that measurements begin to exercise from the 20th week. The maximum values ​​are achieved after the middle of the middle of the third trimester - for example, by the end of 38 weeks the volume can be 95-100 cm. In the same period, it comes to its peak and such a parameter as the height of the uterus bottom. But when the kid will turn over and prepare for the exit to the light, the standing height of the bottom of the uterus will decline and change towards the decrease. And such a parameter, as the circumference of the abdomen region continues to grow. This is often called "belly dropped."

How to shoot measurements from the belly

Despite the fact that it seems quite just to measure the stomach, this is not so easy. After all, it is necessary to do everything correctly, so as not to get an error, which then can lead a woman to the hospital, and also gives her a lot of unpleasant moments and experiences for the state of the child.

The circle is measured so. For a start, an ordinary portno centimeter is taken. It will be optimally necessary to carry out the necessary measurements, when the future mother is worth - in this case, the stomach does not spread on the sides. Navigate when measurements stands on the navel area. As a rule, it is this level that coincides with the first lumbar vertebrae on the back. It is important to remember that it is impossible to measure the circle at the highest point of the protruding abdomen - this measure will be incorrect.

If the indicators differ from the norm is not strongly fundamentally, and it happens once, it is not worth worrying. After all, for example, the number of accumulating waters could change, or the child has grown noticeably.

when you should start worrying

With regular measurements, the gynecologist will be able to quickly notice enough if any deviations from the indicators of the norm appear. Moreover, the same negative turns out to be both an increase and decrease in parameters that are not suitable for the estimated term of "interesting situation".
