Introduction
In general, preterm birth refers to the delivery of an infant before 37 weeks of gestation and may be caused by factors such as unhealthy lifestyle habits, cervical insufficiency, multiple pregnancies, premature rupture of membranes, or hypertension. If a pregnant woman shows signs of preterm labor, it is recommended to seek medical attention promptly and, under a doctor's guidance, receive treatment with medications such as dexamethasone injection or betamethasone injection.
Generally, preterm birth refers to the delivery of an infant before 37 weeks of gestation and may be caused by factors such as unhealthy lifestyle habits, cervical insufficiency, multiple pregnancies, premature rupture of membranes, or hypertension. The details are as follows:
1. Unhealthy Lifestyle
Unhealthy lifestyle behaviors, such as smoking and alcohol consumption, can increase the risk of preterm birth. In addition, poor dietary habits, lack of physical activity, and excessive work may negatively affect the fetal and uterine environment, potentially leading to preterm delivery.
2. Cervical Insufficiency
Under normal circumstances, the cervix begins to dilate only in late pregnancy in preparation for childbirth. However, some pregnant women may experience premature cervical relaxation or shortening, causing the cervix to open early and triggering preterm labor.
3. Multiple Pregnancy
When a woman carries multiple fetuses, the uterus experiences greater expansion and stress, increasing the likelihood of early cervical dilation and raising the risk of preterm birth. Multiple pregnancies may also lead to other complications, such as placental abruption or uneven fetal development, further increasing the risk of preterm delivery.
4. Premature Rupture of Membranes
Premature rupture of membranes—caused by cervical relaxation, weak fetal membranes, or infection—can destabilize the intrauterine environment and potentially trigger preterm birth.
5. Hypertension
If a pregnant woman has hypertension, it may interfere with fetal development and the intrauterine environment, thereby increasing the risk of preterm birth.
If a pregnant woman shows signs of preterm labor, she should seek medical attention promptly. Under a doctor's guidance, medications such as dexamethasone injection or betamethasone injection may be used for treatment. It is also important to improve unhealthy lifestyle habits, avoid tobacco and alcohol, reduce physical activity appropriately, and avoid prolonged standing.
