Initially, according to the condition of the uterus, the obstetrician-gynecologist determines the presence or absence of pregnancy and the length of the woman's stay in an "interesting position". Well, starting from the 20th week of pregnancy, physicians pay special attention to such an indicator as the height of the bottom of the uterus. The fact is that it is at this stage that the uterus grows with the future crumbs, which means that the sides of the small pelvis expand, and the uterus rises higher and higher.
The height of the uterine fundus during pregnancy is the most important indicator that allows you to determine the correct course of pregnancy and fetal development.
How is the height of the bottom of the uterus measured?
Let's start with the fact that the height of the bottom of the uterus allows you to not only determine the duration of pregnancy and the expected date of birth, but also in time to identify possible pathologies in the fetal condition of the fetus, and determine the rate of its development. Measurement of the height of the uterus during pregnancy is determined by the district gynecologist, using a centimeter tape or a so-called tasomer. At the same time, a woman must be in a supine position with her legs straight and an empty bladder.
The indicator of the height of the uterine fundus is the distance from the highest point of the lone articulation and to the highest point of the uterus. The height of the uterine fundus of a pregnant woman is measured at each reception and the results recorded in the card.
What determines the height of the bottom of the uterus?
Note that, despite the existing standard norms that indicate a normal course of pregnancy, it is not uncommon for cases when the indices can differ by 2-4 cm.
Such a difference in figures may depend from the following factors:
- special position of the fetus;
- the size of the fruit;
- the individual physiological feature of the woman's body;
- Amount of amniotic fluid;
- the number of embryos.
However, after the 20th week of pregnancy, the measurement results must comply with standard norms, which are typical for a particular period.
Let's consider what these norms are:
- 16th week of pregnancy - the height of standing of the bottom of the uterus is 6 cm;
- 20 weeks of pregnancy - 11-12 cm;
- 24 weeks of pregnancy - 22-24 cm;
- 28th week of pregnancy - 28 cm;
- 32 weeks of pregnancy - 32 cm;
- 36 weeks of pregnancy - 34-36 cm;
- 38 weeks of pregnancy - 35-38 cm;
- 40 weeks of pregnancy - 32 cm. It is this week that the uterus is already going down.
In the event that there are deviations from the standards of height indicators of the bottom of the uterus, the doctor should prescribe an additional examination to the pregnant woman.
If the indicator does not correspond to the norm, then what?
Note that at a certain period of pregnancy, the compliance of the indicators indicates the normal development of the child, but some deviations still take place and the doctor should follow it. All, of course, individually, so panic in advance if you deviate from the norm. The doctor will notify you, if something goes wrong. For example, a lag in late standards may indicate fetal hypotrophy, which often leads to when the baby is born with a low weight.
Insufficient growth of the uterus may also indicate the lack of water or the presence of infectious and other gynecological diseases. The cause of too low a uterine fundus can also be a transverse presentation of the fetus.
However, we note that if any deviations from the norm are detected, the doctor will prescribe an additional examination and, according to the results, make a decision regarding the treatment. It is not worth worrying, especially since this in no way contributes to a child's health. If you have any questions, do not hesitate to discuss your experiences with your doctor. An experienced gynecologist will tell you in detail about the risks, if any, and prescribe an effective treatment. Therefore, follow the advice of a doctor, take care of yourself and give birth to healthy babies!
