What does the tone of the uterus mean during pregnancy?

In the area of \u200b\u200bthe small pelvis, a woman has a smooth muscle organ, a “cocoon” for the fetus, the uterus. The body of this organ consists of three layers - mucous membrane (endometrium), muscle (myometrium), serous layer (perimeters).

Important: in a non -pregnant woman, the uterus weighs about 50 g, reaches a height up to 8 cm, in width - up to 5 cm. During pregnancy, its weight and size grow rapidly. So, at 39 weeks, the uterus can weigh up to 1.5 kg, reach 38 cm in height and 25 cm in width. The uterine muscles are the strongest in the body of a woman, they are able to push the child during childbirth.

The uterine muscles are always in good shape, they periodically contract and relax. During pregnancy, the tone can be:

  • normal
  • increased (hypertonicity)
  • reduced (hypotonus)

Important: uterine muscles during pregnancy can be reduced. Normally, a woman should not feel these contractions of myometrium, especially since they should not cause her discomfort

The expectant mother should consult a doctor if:

  • she clearly feels the contractions of the uterus (in the lower abdomen pulls, hurts, pulsates)
  • these reductions are long

Similar symptoms can indicate a hypertonicity of the uterine muscles and a possible threat of termination of pregnancy or premature birth. An increased tone is not an independent diagnosis, the causes of this state are various pathological processes in the body of a pregnant woman, as well as adverse external factors. These reasons:

  1. Hormonal disorders. The tone can increase with insufficient production of ovaries, placenta, adrenal glands of female estrogens and progesterone with the simultaneous overturning of male hormones
  2. Congenital vices of the development of female genital organs (underdevelopment, two -horned uterus, others)
  3. Inflammatory processes in the genital organs and organs of a woman’s small pelvis
  4. Infectious diseases, including sexually transmitted
  5. Neoplasms in the body of the uterus (fibroids)
  6. Disorders in the work of the nervous and immune systems of the body of the pregnant woman
  7. Extragenite diseases (diseases of the cardiovascular, urinary systems, so on)
  8. Bad habits
  9. Hard physical labor, overwork
  10. Stress
  11. Depression and anxiety associated with pregnancy and upcoming births

The uterine hypertonicity as a prolonged or constant phenomenon is a danger throughout pregnancy.

  2. Until 28 weeks of pregnancy, the tone can provoke placenta detachment and spontaneous miscarriage
  3. After 28 weeks of pregnancy due to hypertonicity, premature birth activity may begin
  4. The abbreviations of myometry become the cause of the spasm of the vessels of the uterus, therefore, in the second and third trimesters, increased tone is fraught with hypoxia and fetal hypotrophy with mediating disorders of its growth and development
