The uterus of a pregnant woman is the organ to which the attention of gynecologists is directed, since it is here that the birth of a new life takes place. Therefore, its proper development is the key to the health of the unborn child.
Of great importance is such an indicator as the height of the bottom of the uterus during pregnancy (VDM) in its first trimester, since during this period it is important to accurately determine the gestational age of doctors. In the next trimester, the embryo begins to develop faster, which implies an increase in space for it, so the uterus also increases in size. With each week, she increasingly goes beyond the boundaries of the small pelvis, changing its structure and shape.
It can be argued that VDM during pregnancy not only helps to correctly determine its duration, but also indicates the intrauterine state of the embryo, the speed of its development, and also makes it possible to set the date of birth.
At the very beginning of pregnancy, the height of the uterus is measured using a vaginal examination, a little later VDM is measured with a centimeter tape. You need to know that deviations in size by more than three centimeters in the second trimester of pregnancy may indicate violations in the development of the fetus, oligohydramnios, multiple pregnancy or large fetus, as well as the fact that the term was set incorrectly. Therefore, an experienced doctor conducts an additional examination of a woman.
Thus, the distance from the pubic symphysis to the upper point of the uterus is defined as the height of the uterus, during pregnancy this indicator is measured in the supine position of a woman, while her bladder should be empty. The height of the uterus is measured by the doctor at each examination.
Doctors compiled a special table that allows you to determine whether the height of the bottom of the uterus corresponds to the gestation period. Using this table, the gynecologist can judge the normal or unnatural course of the process of bearing a baby. However, it should be borne in mind that the indicators in the table can vary depending on the individual characteristics of the female body, on the size of the embryo and its position in the uterus, as well as on the amount of amniotic fluid. Therefore, VDM during pregnancy is measured along with the circumference of the abdomen. Any deviations in the height of the fundus of the uterus from the norm should alert, because this may indicate placental insufficiency, polyhydramnios or the presence of infection. Infections usually appear as a result of ingestion of an intomegalivarius or herpes virus. Common causes of this include abortion, miscarriage, or cervical insufficiency. Polyhydramnios, in the event of a sharp formation, is a great danger to the fetus, as this indicates infection or developmental abnormality. In such cases, pregnancy is most often terminated, but they can puncture the amniotic fluid so that excess amniotic fluid comes out.
Larger sizes of the uterus may also indicate that a woman has a disease such as fibroids. It should be noted that it does not pose a threat to the fetus and does not affect the course of pregnancy. However, control by the doctors over the course of this disease is necessary, since at some stage of pregnancy, myoma can become inflamed. If this happens, a cesarean section is performed.
Thus, VDM during pregnancy is measured in centimeters and corresponds to the term. For example, at a height of the uterus of twenty centimeters, the gestational age will be twenty weeks.
Pregnancy is an important stage in the life of every woman. Its normal course ensures the healthy development of the unborn child, therefore, gynecologists, at each visit to the expectant mother, conduct research on the circumference of her abdomen and VDM, which during pregnancy play an important role, since they can indicate various violations in the formation and development of the fetus.
