Everyone must have heard of premature birth in life, but have you ever learned about the relevant knowledge of premature birth in pregnant women? Today, let's learn about what causes premature birth in pregnant women and what are the causes of premature birth in pregnant women.

What causes premature birth?

First, maternal factors may play a leading role, such as hypertension, severe anemia, malnutrition and acute infectious diseases during pregnancy, or heavy physical labor, mental stress, excessive fatigue, multiple births, etc. in the later period. There are still mothers addicted to drugs abroad. Factors of the uterus, placenta, umbilical cord and accessory tissues include: bicornuate uterus, uterine fibroids, uterine septum malformation, endometritis, placenta previa, placental abruption, umbilical cord is too short, torsion, knotting, premature rupture of amniotic membranes, polyhydramnios, etc. Secondly, fetal factors: twins are more common, and premature birth can also be caused by fetal malformations. Recently, it is believed that 50%~80% of premature births are related to chorioinflammation, and its pathogens can be Escherichia coli, group B hemolytic streptococci, etc. Finally, obstetric interventions such as improper amniocentesis.

What are the causes of premature birth?

1. Mothers with a history of premature birth have a higher chance of having another premature birth than ordinary women.

2. Multiple miscarriages or abortions can cause varying degrees of damage to the uterus, increasing the risk of premature birth.

3. Gestational age is too early or too late. Doctors at the Sainte-Justine Children's Hospital at the University of Montreal in Canada studied 165,282 newborns and found that women aged 30-34 have the lowest risk of premature birth.

4. Congenital problems of the uterus: Uterine malformation, cervical insufficiency, loose or short internal os, these congenital factors make premature birth more likely.

5. Over-expansion of the uterus with twins or multiple babies, and excessive amniotic fluid. Most twins or multiple babies are born prematurely. Twins are usually born at 37 weeks, and triplets at 34 weeks.

How to prevent premature birth in pregnant women

1. Treatment of genital tract infection When suffering from genital tract infection, you should seek medical treatment in time.

2. Avoid fatigue and external stimulation. It is best not to travel long distances in the late pregnancy to avoid bumpy and tired roads; do not go to crowded places to avoid hitting the abdomen; when walking, especially when going up and down stairs, be sure to take steady steps; do not stand or squat for a long time; sexual intercourse is prohibited in the late pregnancy.

3. Maintain a good living condition During pregnancy, pregnant women should pay attention to improving their living environment, reducing labor intensity, and increasing rest time; the greater the psychological pressure on pregnant women, the higher the incidence of premature birth, especially tension, anxiety and depression are closely related to premature birth. Therefore, pregnant women should maintain a calm state of mind, eliminate tension, avoid adverse mental stimulation; take reasonable and sufficient nutrition, and rest in bed more in the late pregnancy, and take the left side lying position to reduce the pressure from the uterine cavity to the cervical opening.

4. Pay attention to your own health. If a pregnant woman suffers from complications such as heart disease, kidney disease, diabetes, hypertension, etc., she should actively cooperate with the doctor's treatment; pregnant women with pregnancy-induced hypertension syndrome, twin or multiple pregnancy, placenta previa, polyhydramnios, etc. must follow the doctor's advice, actively do a good job of their own health care during pregnancy, detect abnormalities in time, and seek medical treatment as soon as possible.

5. If necessary, for patients who had premature birth in the previous pregnancy due to cervical relaxation, cervical cerclage should be performed between 16 and 20 weeks of pregnancy (before the gestational age of the previous premature birth).

What are the dangers of premature birth in pregnant women?

Premature birth is one of the main causes of neonatal death. Once premature birth occurs, pregnant women will become nervous and often unprepared and caught off guard. In order to save the baby, sometimes the chance of surgical delivery is increased. More importantly, premature birth brings harm to the baby. If the fetal lungs are not yet mature during premature birth, the lungs of premature babies cannot expand well after birth, and breathing difficulties will occur. In severe cases, death may occur. The liver of premature babies is immature and the liver enzyme system is not fully developed.
