Of course, there are mean currency deadlines for the growth of the uterus and, accordingly, the appearance of the tummy. On average, it is difficult to notice something up to a 12-week period. By the 16th week, it becomes a noticeable barely rounded tummy. And already by the 19-22th - pregnancy is visible to everyone. These deadlines are correct when the abdomen begins to grow at the first pregnancy. Because when a woman is waiting for the child for the first time, a small tummy begins to go on the fourth month and becomes noticeable to the seventh. But most often in each case, it is necessary to take into account the individual characteristics of the structure of the body and the circumstances of the tool.
Normally, by 20 weeks, it is already impossible to hide from others the future mom's status. At about the same time, you can feel the first movements of a small little man. Tracking how the growth occurs, you can independently, with the help of a portno centimeter. With measurements, one end of a centimeter tape is applied to the navel of the front. Measuring volume, follow the tape on the back, crossed the point in the middle of the lower back. When you close the tape on the navel, the figures obtained will show the current size.
If children are two, then they grow twice as fast. Therefore, the uterus in this case is also accelerated in growth. Accordingly, the noticeable "PUC" will appear faster: already in the first trimester. Yes, and the weight of the woman will double more.
The result must comply with the standards - for each pregnancy week there are indicators. At the same time, the average change in the volume of the abdomen is around the 1st centimeter a week, starting from the 20th week of pregnancy.
Definition of coolant allows doctors to monitor the development of the fetus, and in case of increasing indicator with the norm - take timely measures. More information about the norms of development of the fetus for weeks, we wrote in this article.
In any case, you should not make hasty conclusions, relying only on the size of the abdomen. If you are disturbing that you have too small or, on the contrary, a big tummy, you should tell a doctor about my fears.
A frequent question that occurs in the crowded emotions of the future mother - on what a stomach begins to grow on pregnancy. They set themselves for various reasons: when you have to change the wardrobe, the pregnancy proceeds correctly, how long can the position be hidden, from what deadline will have to postpone sports and others. Reply to all questions in order.
How quickly grows belly during pregnancy. The following tendency is observed: there are practically no changes for the first months. The situation is manifested in changing the internal state of the woman: toxicosis, aggravated smell, edema, drowsiness and irritability. From a certain period, the figure begins to actively change, and the volume of "waist" increases almost daily.
During what the stomach increases during pregnancy? Due to the growth of the fetus, the uterus and an increase in the number of arrogant water - the habitat of the future kid. Let's talk more about each of the listed components.
The sizes first of the fetal egg, and then the fetus is determined by the results of ultrasound research (ultrasound). With the help of a transvaginal ultrasound (the sensor during this study is introduced into the vagina), a fruit egg can be found after 2-3 weeks of its development, the period of pregnancy, which is counted from the first day of the last menstruation, is 6-7 weeks. The diameter of the fetal egg on this period is 2- 4 mm.
The increase in the size of the uterus occurs throughout the pregnancy. In the first few weeks, the uterus has a pear shape. At the end of the 2nd month of pregnancy, its dimensions increase approximately three times and it has a rounded form. During the second half of pregnancy, the uterus retains its rounded forms, and at the beginning of the third trimester acquires an egg-shaped form. Before pregnancy, the mass of the uterus on average is 50-100 g, and at the end of pregnancy - 1000 g. The volume of the uterus in the end of pregnancy increases more than 500 times. During the pregnancy, each muscular fiber extends 10 times and thickens approximately 5 times. Significantly increases the vascular network of the uterus, according to its oxygen regime, a pregnant uterus approaches such vital organs, like a heart, liver and brain.
These parameters can be determined by measuring the uterus using the methods of outdoor obstetric research. This is measured by the so-called standing value of the bottom of the uterus. However, at the beginning of pregnancy, while the uterus does not go beyond the limits of pelvic bones, an increase in the size of the uterus can be determined using a vaginal study, it is carried out in a gynecological examination or ultrasound.
Standing the bottom of the bottom of the uterus The doctor determines with each next inspection using a centimeter tape: it helps to navigate in the growth rate of the belly. The doctor measures the distance from the upper edge of the Lonatic articulation to the top of the uterus - its bottom. Approximately a standing height of the bottom of the uterus in centimeters corresponds to the period of pregnancy in weeks. For example, if the standing height of the uterus is 22 cm, the term of pregnancy is 22 weeks.
Reducing the height of the bottom of the uterus is possible with the transverse position of the fetus, when the baby in the uterus is located so that the head and the pelvic end are on the sides. With the transverse position of the fetus, childbirth through natural generics are impossible.
The sizes of the uterus more of the alleged period of pregnancy are also with multipleness. As is known, multiple pregnancy belongs to high-risk pregnancies: the likelihood of various complications increases with it.
The uterus can increase with a significant multi-way state, when the amount of accumulating waters exceeds the norm, reaching 2-5 l, and sometimes - 10-12. This pathology occurs in diabetes mellitus - impairment of sugar, rezes-conflict pregnancy - when antibodies against rhesus-positive erythrocytes of the fetus are produced in the body of a rhesus-negative mother, with acute and chronic infection, with anomalies of fetal development. Of course, all these states require close attention of doctors.
, you can plan a wardrobe update or visits to secular dinners. Some women want to hide the "interesting position", others wish to boast before others. In any case, for future mothers it is very important when a round tummy becomes the naked eye.
The body of each person is individual, so you call the exact time on which the tummy begins to grow, it is impossible to determine. For some future mothers, pants cease to converge on the waist for the 8th week of gestation. Others practically do not change externally until the third trimester of pregnancy. A lot of cases are known to science, when it is unnoticed for the people around others and the most childbirth.
Since the processes listed above occur in a certain sequence and according to a given algorithm, experts have established approximate terms when the active growth of the tummy is begins. In most cases, external changes are still noticeable only by the future mother. The surrounding will notice the "interesting situation" in just a month, approximately 20 weeks.
Gynecological obstetricists agreed that the stomach rounding could not take up to 12 weeks of gestation. This is due to the fact that the uterus is under the pubic bone, so it can not be thrown forward.
appearance and growth rate of the fetus (and with it and the tummy) depend on the set of factors. Someone the waist increases faster, the rest is much slower. However, there are some patterns that the majority of future mothers are subject.
In the first trimester, the stomach does not grow. If it is still increasing, then slightly, it is noticeable only to a woman. The embryo is still very small, the uterus occupies a little space in a small pelvis. For example, in 3-4 weeks it resembles a chicken egg, on the 8th week - goose. The uterine body is still not reaching the Lona Jim. Only at the end of the first trimester, the bottom of the uterus begins to rise above the pubic symphysome.
