PREGNANCY / growing up lives?

growing stomachOne of the indisputable signs of pregnancy is growing belly. And why and how it grows? It would seem that the answer is obvious: the belly is growing because the child is growing up, and it happens all expectant mothers alike, because any normal pregnancy lasts 9 months. Actually everything is much more complicated, and especially the growth of the abdomen can about ways to talk to a specialist...

What during pregnancy increases the stomach? Due to the growth of the fetus, uterus and increasing the amount of amniotic fluid - habitat unborn baby. Let's talk more about each of the listed components.


The dimensions of the first of the ovum, and then the fetus is determined by the results of ultrasound examination (sonography). Using transvaginal ultrasound (sensor during this research into the vagina) the fertilized egg can be detected already after 2-3 weeks of its development, the period of pregnancy, counting from the first day of the last menstrual period, is at this time 6-7 weeks. The diameter of the ovum at this period of 2-4 mm.

On the 8th week of development is the 10th week of pregnancy, the diameter of the ovum reaches 22 mm

In 12 weeks of pregnancy length of the fetus is 6-7 cm, body weight of 20-25 g ultrasound shows that the fertilized egg is almost completely fills the uterine cavity.

By the end of the 16th week of pregnancy the length of the foetus is 12 cm, and body weight -100,

At 20 weeks, the length of the fetus is already 25-26 cm, weight - 280-300,

At 24 weeks the length of the fetus is about 30 cm, weight - 600-680,

At 28 weeks the length of the fetus is 35 cm, weight - 1000-1200,

At 32 weeks the length of the fetus reaches 40 - 42 cm, weight - 1500-1700,

At 36 weeks, these figures are respectively 45-48 cm and 2400-2500,

Weight full-term fetus at the time of delivery is 2600-5000 g, length - 48-54 see

The uterus

The increasing size of the uterus occurs during the whole pregnancy. For the first time a few weeks the uterus is a pear shape. At the end of the 2nd month of pregnancy its dimensions increase by about three times, and it has a rounded shape. During the second half of pregnancy the uterus retains its rounded forms, and at the beginning of the third trimester becomes ovoid shape. Pre-pregnancy weight of the uterus on average 50-100 g, and at the end of pregnancy - 1000 Volume of the cavity of the uterus in late pregnancy increases more than 500 times. During pregnancy every muscle fiber is extended 10 times and thickens about 5 times. Significantly increased vasculature of the uterus, its oxygen regime pregnant womb approaches such vital organs as the heart, liver and brain.

These parameters can be determined by measuring the uterus using the techniques of external obstetric examination. To do this, measure the so-called value of the symphysis of the uterus, but in the beginning of pregnancy as the uterus does not extend beyond the pelvic bones, the increasing size of the uterus can be determined by vaginal examination (it is held during gynecological examination or ultrasound.

The height of the symphysis of the uterus, the doctor determines at each regular inspection using measuring tape: it helps to understand the growth of the abdomen. The doctor measures the distance from the upper edge of the pubic bone to the top of the uterus is its bottom. Approximately the height of the symphysis of the uterus in centimeters corresponds to the period of pregnancy in weeks. For example, if the height of the symphysis of the uterus is 22 cm, gestational age 22 weeks.

Amniotic fluid

The growth of the volume of amniotic fluid (amniotic fluid) is uneven. So, 10 weeks pregnant with their volume is 30 ml, 13 - 14 weeks - 100 ml, 18 weeks -400 ml, etc. the Maximum amount of notes to 37 - 38 weeks (average-1000-15 000 ml). Towards the end of pregnancy the amount of water may be reduced to 800 ml. With postmaturity (41-42 weeks) observed a decrease in the volume of amniotic fluid (less than 800 ml).

If the size of the stomach do not correspond to norm... The rate of increase of the uterus, and hence growth of the abdomen should strictly enough to meet the above parameters, as they are an important indicator of normal pregnancy.

In the early stages, when the uterus has not yet palpated through the anterior abdominal wall, the discrepancy in size to the expected life of the pregnancy may be a sign of ectopic pregnancy, when the fertilized egg is most often develops in the fallopian tube.

The excess of the estimated sizes of pregnancy is typical for this pathology, as chorionepithelioma - tumor growing from the placental tissue and represents a large number of small bubbles. When this tumor fetus dies, and to preserve the health of the mother must timely treatment.

In the later stages of pregnancy lag in the rate of increase of the fundus of the uterus most often during fetal malnutrition, that is, when the delay of its growth. In this pathology, the baby born at term birth weight less than 2600 g, is hampered by its adaptation to extrauterine life.

Oligohydramnios may also be the reason that the size of the uterus is less than expected. Among the possible causes of this complication of hypertension in the mother, infectious-inflammatory diseases, inflammatory diseases of female sexual sphere, the defeat of the excretory system of the fetus, placental insufficiency, preeclampsia is a serious complication of pregnancy in which there is generalized vasospasm; it is usually manifested by edema, high blood pressure, protein in the urine.

Reducing the height of the fundus of the uterus is possible with the transverse position of the fetus, when the baby in the uterus is positioned so that the head and the pelvic end on the sides. In transverse fetal position for a normal vaginal delivery impossible.

The size of the uterus longer than expected period of pregnancy are also in multiple pregnancy. As is known, multiple pregnancy refers to a pregnancy high risk: when it increases the likelihood of various complications.

Will stretch marks?

The skin on the stomach is stretched by increasing the duration of pregnancy. Will do this process without a trace?

I must say that skin damage - the so-called stretch marks by increasing the volume of the uterus depends of course on the rate of growth of the belly, but for the most part their appearance is determined by the characteristics of the skin of the mother. Of course, the likelihood of a few stretch marks increased if the fruit is large, quickly adds a lot or if there is polyhydramnios, but the determining factor is the condition of collagen, elastin fibers.

For the prevention of stretch marks, especially during the intensive growth of the abdomen in the third trimester of pregnancy - you can use a tool that improves the skin condition. This is a special cosmetics for pregnant women, containing vitamins a And E, as well as substances that improve blood circulation in the skin. Because during pregnancy, the skin often becomes more dry, you can use moisturizing creams for pregnant women; they will also help to prevent the appearance of stretch marks. To prevent the appearance of stretch marks, you can also massage that improves circulation in the skin. The technique of this massage is not difficult: it is necessary to stroke the abdomen in a circular motion, to positivity the skin on the periphery of the abdomen. With the threat of termination of pregnancy, this massage should not be carried out, as it may provoke an increase in uterine tone.

The uterus may increase at a significant polyhydramnios - state, when the amount of amniotic fluid exceeds the norm, reaching 2-5 l, and sometimes 10-12. This disease occurs in diabetes - impaired absorption of sugar, rhesus pregnancy - when the body of RH-negative mother produces antibodies against RH-positive red blood cells of the fetus, in acute and chronic infection, abnormal development of the fetus. Of course, all of these States require the attention of doctors.

The uterus can grow faster than normal with large fruit size. In turn, large fruit may be due to a genetic features, and diabetes in the mother during this pregnancy. Large fetus increases the risk of complications during childbirth, and diabetes requires treatment.

Thus, the pace of change increasing the height of the fundus of the uterus may be an indicator of various pathologies of the mother and, more fruit. Therefore, if at the next reception the doctor detects that the height of the symphysis of the uterus does not correspond to the duration of the pregnancy, he appoints additional research to clarify the factors that caused the increase or decrease in the rate of growth of the abdomen.

The shape of the abdomen

Of particular importance in the second half of pregnancy has the shape of the abdomen. In a normal pregnancy, and the correct position of the fetal abdomen is ovoid (egg-shaped) form; when polyhydramnios belly becomes spherical, and when the transverse position of the fetus takes the form of a transverse oval. A special form has a belly in the third trimester of pregnancy in women with a narrow pelvis: in nulliparous abdomen pointed, as if pointed up, multiparous - bit flabby.

Thus, the shape of the abdomen is also important to determine the characteristics of the course of pregnancy, however, scientific data on what it is possible to determine the expected gender of the child, unfortunately, no.

The belly of the mother will be visible to others only to 4-5th month of pregnancy. But we now know that its growth begins much earlier. So from the very beginning, waiting for the baby, a pregnant woman should treat herself carefully and gently.
