Many pregnant women worry about premature birth, as it may mean that the baby is at risk of being unhealthy. In order to avoid premature birth, some pregnant women may want to avoid factors that cause premature birth. So what factors can lead to premature birth?
Firstly, one important reason for premature birth of the fetus is infection of the chorionic and amniotic membranes. If the chorion and amniotic membrane are infected, it can lead to premature rupture of the membranes, which is a common symptom of premature birth in most fetuses. The infection may originally come from the uterus or from outside, but regardless of its source, maintaining genital hygiene during pregnancy is important.
Secondly, if a pregnant woman has more than one fetus in her womb, premature birth may also occur. When a pregnant woman has more than one fetus in her abdomen, she also needs more amniotic fluid, which can cause an increase in the pressure of hunger in the uterine cavity, and the fetus may be premature. Due to the fact that this is caused by the number of fetuses, pregnant women can only consult a doctor during pregnancy to take necessary preventive measures.
Furthermore, in mid pregnancy, if a woman's cervix is forced to dilate, it may also lead to premature birth of the fetus. When the cervix is passively dilated, the amniotic sac in the uterine cavity will instantly bulge towards the cervix, causing a change in tension and rupture of the fetal membrane, leading to premature birth of the fetus. It is precisely for this reason that doctors advise pregnant women not to engage in sexual activity with their husbands during pregnancy.
