The best age for three C-sections is before the age of 35. It is not just C-sections, but women who have had normal births are also advised that the best time to get pregnant is before the age of 35. If the pregnancy is more than 35 years old, it is considered advanced maternal age. Nowadays, women of advanced maternal age can develop many obstetric complications such as gestational hypertension, gestational diabetes, and gestational heart disease, all of which increase the risk of these diseases. Advanced maternal age may also lead to an increased risk of chromosomal abnormalities in the fetus. If you want to get pregnant, it is best to do so before the age of 35. For women who get pregnant after the age of 35, it is important to have a thorough prenatal checkup and a prenatal diagnosis to be most reliable. It is now clinically recommended that pregnant women who have already had two cesarean sections are generally not advised to get pregnant again. The risk of uterine rupture is greatly increased if she becomes pregnant again, and poor uterine contractions can also occur after delivery, leading to postpartum hemorrhage.
