Most preterm births occur after natural or unintended delivery (as opposed to medically necessary preterm birth, which refers to delivering the fetus as quickly as possible to protect the mother and fetus). Predicting who will have risk factors for prenatal pain is difficult. But some women with risk factors did not experience labor pains, while other women with unknown risk factors experienced labor pains before their due date.
About half of the women who have been confirmed by professional doctors to have normal prepartum uterine contractions (no premature rupture of membranes before 37 weeks) will definitely need assisted delivery throughout the delivery process. Most preterm births occur after natural or unintended delivery (as opposed to medically necessary preterm birth, which refers to delivering the fetus as quickly as possible to protect the mother and fetus).
Experts say spontaneous labor pains are usually the result of a combination of factors. The most common medical risk factors for spontaneous prepartum pregnancy are: Twins, triplets, or multiple births (the use of assisted reproductive technology or superovulation increases the chance of multiple births, both of which can lead to preterm birth and medical comorbidities) premature birth.
Pregnant women have lower body mass index
smoking during pregnancy
Frequent contractions
Other risk factors that increase prepartum labor pain include:
Using cocaine or ephedrine
polyhydramnios
Ultrasound shows significant shortening of the cervix
Less common factors associated with spontaneous labor pain include:
The cervix does not close completely until the due date (cervical insufficiency)
A history of two or three miscarriages, each of which increases the risk of the next miscarriage
Getting pregnant again less than three months after the pregnancy ended
Uterine problems, such as an abnormally shaped or overstretched uterus (polyhydramnios or twins or multiples can overstretch the uterus and cause the amniotic sac to rupture)
Previous cervical surgery, such as cervical conization biopsy
The pregnant woman herself, whose mother took too much estrogen before birth
Being underweight or gaining too little weight during pregnancy
Pregnant women whose jobs require them to stand for long periods of time or have high-stress jobs, such as factory workers, retail workers, and nurses
Taking large doses of licorice, 227 grams of licorice per week, can increase the degree of drug-induced pain in the body
Severe mental stress during pregnancy
Unbalanced diet
Medically unavoidable premature birth
One in four preterm births is medically unavoidable, often caused by dangerous pregnancy complications. These are called indicated preterm births. For indicated preterm birth, the most common medical risk factors, in descending order, are:
preeclampsia
fetalAdverse stress in children
Fetal hypoplasia (intrauterine growth restriction) reduces the chance of healthy fetal survival
Premature placental separation is the premature separation of the placenta from the uterine wall.
