Introduction

If the placenta is marginal or low-lying—located in the lower uterine segment but not completely covering the cervical os, with a distance of less than 2 cm from the cervical os—vaginal delivery may be considered. However, if the placenta is centrally or partially previa—completely covering the cervical os, or within 3 cm of it—vaginal delivery is generally not recommended, and cesarean section should be performed under medical guidance.

In general, whether vaginal delivery is possible with a low-lying placenta depends on the placenta's exact position. Vaginal delivery may be feasible in cases of marginal placenta previa or low-lying placenta; however, it is not recommended for complete or partial placenta previa. If any discomfort occurs, prompt medical attention is advised. Detailed analysis is as follows:

If the condition is marginal placenta previa or low-lying placenta—meaning the placenta is located in the lower uterine segment but does not completely cover the cervical os, with a distance of less than 2 cm from the cervical os—and if the fetus is in normal condition, labor progresses quickly, and there is minimal bleeding, vaginal delivery may be considered.

However, if the condition is complete or partial placenta previa—where the placenta completely covers the cervical os, located less than 3 cm from the cervical os—and if the fetus is large, the placenta is difficult to detach, or there is significant bleeding, vaginal delivery is generally not recommended. In such cases, cesarean section under medical guidance is preferred to ensure the safety of both mother and baby.

During pregnancy, it is important to maintain a balanced diet, avoid greasy and spicy foods, prevent excessive fatigue, maintain regular作息 (sleep-wake cycles), and attend routine prenatal checkups to safeguard the health of both mother and fetus.

Is low-lying placenta a common phenomenon?

In general, placenta previa is not a common condition. Under normal circumstances, the placenta usually attaches to the anterior wall, posterior wall, or lateral wall of the uterus, and these locations do not affect placental blood circulation or the normal development of the fetus. Placenta previa refers to a condition in which the placenta attaches to the lower segment of the uterus, with its edge reaching or covering the internal cervical os, which may cause vaginal bleeding during pregnancy, preterm labor, and other complications.

What does it mean to have a low-lying placenta?

In general, an anterior uterus typically refers to a uterus positioned towards the front of the body, which is one way to describe the location of the uterus. To avoid misdiagnosis or delayed treatment, it is recommended to undergo evaluation under the guidance of a qualified physician. In daily life, maintaining healthy lifestyle habits, such as avoiding prolonged sitting, engaging in moderate exercise, and undergoing regular gynecological examinations, can help maintain pelvic health.

Is a low-lying placenta at 13 weeks of pregnancy common?

In general, a low-lying placenta at 13 weeks of pregnancy is a relatively common phenomenon in clinical practice. If there are no abnormal symptoms such as vaginal bleeding or abdominal pain, it may be considered normal. During pregnancy, it is important to maintain a healthy lifestyle, including bed rest, adequate rest, avoiding excessive fatigue and sexual activity, which can help reduce pressure on the placenta.
