Introduction
Under normal circumstances, women with a scarred uterus should pay attention to pre-pregnancy examinations, timing of pregnancy, regular prenatal checkups, controlling fetal size, and selecting the mode of delivery when having their second child. During pregnancy, the expectant mother should also avoid strenuous exercise and heavy physical labor, and reduce sexual activity to lower the risk of uterine scar rupture. At the same time, she should maintain good lifestyle habits, such as eating a balanced diet and ensuring adequate sleep.
Generally, women with a scarred uterus should pay attention to pre-pregnancy examination, timing of pregnancy, regular prenatal checkups, control of fetal size, and selection of appropriate delivery methods when planning a second pregnancy. A detailed analysis is as follows:
1. Pre-pregnancy Examination
Prior to planning pregnancy, consultation with a specialist and comprehensive pre-pregnancy examinations are recommended, including evaluation of endometrial thickness, ovarian function, and fallopian tube patency, to determine whether another pregnancy is advisable. If the uterine scar is severe, scar repair surgery might be necessary first, involving the opening of tissue surrounding the uterus followed by uterine repair.
2. Timing of Pregnancy
If there is a history of cesarean section or other uterine surgery, it is recommended to wait at least 18–24 months before considering another pregnancy, to reduce the risk associated with an incompletely healed uterine incision.
3. Regular Prenatal Checkups
Women with a scarred uterus should undergo regular prenatal examinations during pregnancy. Ultrasound and other diagnostic methods should be used to monitor the location of the gestational sac, the relationship between the placenta and the scar, as well as the growth and development of the uterus and fetus. Any abnormalities should be evaluated by a physician promptly.
4. Control of Fetal Size
Appropriate nutritional intake should be maintained during pregnancy to avoid excessive fetal growth, which can increase tension on the uterine scar and raise the risk of uterine rupture.
5. Selection of Appropriate Delivery Method
Due to potentially reduced strength of the uterine wall, pregnant women should fully discuss with their physicians and choose an appropriate delivery method based on individual circumstances.
During pregnancy, women should also avoid strenuous exercise and heavy physical labor, and reduce sexual activity to lower the risk of uterine scar rupture. Additionally, maintaining healthy lifestyle habits, such as balanced nutrition and adequate sleep, is important to ensure maternal and fetal well-being.
