Premature birth. Causes

1. Isthmic-cervical insufficiency is a weakness of the cervix, as a result of which the uterus cannot hold the fetal egg inside. The main causes of cervical insufficiency are as follows:

  • Injuries of the cervix during previous pregnancies: large fruit, rapid delivery, use of forceps or vacuum during delivery, etc.
  • Operations on the cervix.
  • Infectious diseases of the cervix uteri: candidiasis, mycoplasma, chlamydia, herpes, megalovirus infection, bacterial vaginosis.
  • Endocrine disorders associated with thyroid hormones, decreased ovarian function or increased levels of male sex hormones, which lead to changes in the structure of the cervix.
  • Cervical malformations.
  • Additional load on the cervix (multiple fetuses, polyhydramnios, large weight of the child).

2. Uterine fibroids.

3. Anatomical defects of the uterus (for example, two-horned uterus).

4. Infectious diseases (especially in severe form, with high fever): influenza, tonsillitis, hepatitis, rubella.

5. Heart defects, a tendency to hypertension, chronic diseases of the liver, kidneys, diabetes.
