As is known, normal in pregnancy with an increase in the period, there is a change in the size of the uterus in a larger direction. However, some women at the next examination of the gynecologist hear from the doctor the conclusion that this parameter does not correspond to the term of gestation. Let's take a closer look at this situation and try to establish the main reasons for the fact that the size of the uterus does not match the period of pregnancy.
What can cause a mismatch in the size of the uterus for a period?
It should immediately be noted that not always a woman can accurately name the last date of the month, which makes it difficult to determine the time of conception of the fetus. As a result of this, a situation may develop where the size of the uterus at the early stages of pregnancy does not meet the established standards. In order to determine the size of the uterus during pregnancy, doctors use a survey such as ultrasound.
However, in most cases, a discrepancy between the size of the uterus and the term is a sign of any violation. So the small size of the uterus during pregnancy can be a sign of an undeveloped pregnancy. This often happens at short notice, for various reasons, which sometimes can not be established. In such cases, the embryo dies and the pregnancy ends with an operation to remove it from the uterine cavity.
If we talk about late terms (2, 3 trimester), then in such cases, the discrepancy in size is caused by such a violation as the fetal development retardation syndrome. This is not uncommon in the presence of hypoxia, and a small supply of nutrients to the fetus. It is worth noting that this phenomenon can be observed in malnutrition, which also negatively affects the development of the baby.
What are the reasons that the size of the uterus is longer than the gestation period?
The main cause of the opposite situation can be a large fetus, multiple pregnancy, polyhydramnios. Also, when establishing the pathology that caused this, doctors must exclude the disruption of the endocrine system, for example, diabetes mellitus.
Thus, it is necessary to say that if the size of the uterus during pregnancy according to the results of ultrasound does not correspond to the norm, the pregnant woman needs a survey and an establishment of the cause.
