At the earliest dates of gestation, the size of the genital organ is extremely important, since it is precisely it that makes it possible to establish an indicative period of pregnancy and the age of the fetus. But after 2 months from the moment of fertilization, the height of the standing of the uterus during pregnancy is more carefully studied. This indicator is necessary to exclude the probability of an abnormal increase in the organ and its passage beyond the pelvic floor.
Why measure the height of the bottom of the uterus?
These data help the midwife to assess the rate of embryo development within the genital organ, to study the status of the uterus, to specify the period of gestation and to put an approximate date of delivery. Measurement of the height of the uterine fundus by weeks occurs in conditions of female consultation, when the gynecologist establishes this value with the help of special devices.
The establishment of this indicator should take place immediately after urination. The pregnant woman should lie on her back and stretch out her legs. The doctor measures the circumference of the tummy and determines if the height of the bottom of the uterus corresponds to the norms of the particular patient. All this is recorded in the woman's exchange card in order to be able to follow the dynamics of changes in indicators as the period of gestation increases.
Table of height of the bottom of the uterus
In obstetric practice, there is a special table that allows you to adequately judge any deviations from the norm when setting the indicators at a specific time. So, for example, the height of the bottom of the uterus in 16 weeks should be 14-16 centimeters, which is a generally accepted standard. However, there are factors that can influence the uneven and abnormal decrease or increase in indicators. These include:
- pregnancy with several fruits;
- the location of the child in the uterus and its size;
- the amount of amniotic fluid and so on.
Already at week 17, the height of the bottom of the uterus will be 17-19 centimeters, and continue to grow steadily. At this time the uterine bottom is located between the pubis and the navel. The height of the bottom of the uterus at 18 weeks of gestation and up to the 19th varies in the interval 16-21 cm. The genital organ is located about 2 fingers below the navel. The height of the uterine fundus of 40 cm is typical for gestational age of 22 or 23 weeks. The index continues to grow steadily, like the fetus itself.
Already at 28 weeks the height of the bottom of the uterus is about thirty centimeters, and the muscle is located 2-3 fingers above the navel of the pregnant woman. Do not get upset in advance, if your indicators do not match the norms. The reason for this may be an incorrectly delivered term, and not the presence of any pathology of pregnancy or fetus. At the gestation period of 38 weeks, the height of the uterine fundus reaches the chest of the woman and ceases to grow. The genital organ gradually descends and is prepared for resolution from the burden.
Measurement of the height of the uterine fundus before giving birth makes it possible to establish the estimated weight of the child and decide on the tactics of conducting the process of delivery. Again, do not lose sight of the individual characteristics of each organism and the process of gestation.
If the height of the bottom of the uterus is less than the time, then the very real reasons for this phenomenon
The height of the uterus bottom is longer than the term, it can accompany pregnancy with several fruits, a large amount of amniotic fluid. Also, it can be a sign of bearing a very large child.
In any case, if the height of the uterine fundus has decreased or exceeded the norm, additional studies should be conducted on more accurate equipment.
