Tone of the uterus during pregnancy

Uterus in the body of a woman is the main body responsible for the normal development of future offspring. From her condition depends the ability of a woman to bear childbirth. The structure of the uterus can be represented in the form of three layers:

1. Endometrium (mucous layer)
2. Myometrium (composed of muscles)
3. External (is a thin film that is covered by the uterus)

The muscular layer of the uterus is periodically reduced, since this ability is necessary to carry out the birth process naturally, therefore any gynecologist tracks the tone of the uterus during pregnancy. In cases where often the contraction of the walls of the uterus, it is customary to talk about hypertension - too active activity of the uterus. During childbirth, hypertension is considered a positive phenomenon, as frequent contraction of the walls of the uterus seems to push the fetus, which facilitates and accelerates the birth process. However, this phenomenon during pregnancy adversely affects the condition of the fetus and can lead to the termination of pregnancy.

The tonus during pregnancy increases due to various causes. For example, if a pregnant woman gets a lot of stress, that is, the nervous system is in a restless state. And if earlier it held back the walls of the uterus from excessive cuts, now it might simply not be in time to fulfill this function. Tone in pregnant women becomes palpable in the last trimester, when the nervous system begins to increase excitability, and as a result, the reduction of the walls of the uterus.

An increase in the tone of women in early pregnancy may occur due to the inadequate release of a hormone called progesterone. Most often, progesterone is produced in less quantity, when the woman has an elevated level of male hormones, which block progesterone. Due to the lack of this hormone, the uterus can not develop normally, so it does not grow evenly with the fetus. When the small uterus has to stretch, the muscle layer begins to contract, trying to return to its previous state. Such activity can lead to miscarriage.

The tone of the uterus during pregnancy will certainly increase if in the body of a woman such serious diseases as, for example, a tumor or any other inflammatory or hormonal illness begin to develop. A woman in late pregnancy may experience an increased tone. As a rule, in such cases, the activity is caused by too much stretching of the uterine walls during polyhydramnios or multinodalities. This can happen even if the fetus actively develops and becomes sufficiently large. These situations can not be ignored, as they can lead to premature pregnancy. Therefore, it is necessary to constantly consult with the attending physician and undergo all scheduled examinations.

Increased tone of the uterus can manifest as pains in the lower abdomen and lower back. And in the third trimester, cramping pains and a hard belly are added to these symptoms . If these symptoms are present, it is not superfluous to have an unscheduled check with a specialist, since a negligent attitude can lead, if not to miscarriage, to complications in the development of the fetus. After all, strong contractions contribute to the detachment of the placenta, as a result of which oxygen and all the necessary substances come in a smaller volume.

The tone of the uterus during pregnancy is diagnosed simply and easily. Any obstetrician-gynecologist is able to determine an increased contraction of the uterine walls even with a simple examination. Of course, then there is confirmation of the diagnosis with ultrasound or tonicity - this is a special device that allows you to determine the tone of the uterus during pregnancy, which is applied to the woman's tummy.
