A woman over 35 years of age is considered to be a woman of advanced maternal age. In clinical practice, the term “advanced maternal age” is used to refer to the optimal age for giving birth, and it is defined that a woman over 35 years of age is considered an advanced maternal age. The optimal age for a woman to give birth is between 24 and 30 years old, when she is in better physical condition, has a lower risk of giving birth, and recovers more quickly after giving birth. Therefore, it is advisable to give birth at the optimal age for childbearing. The risk of gestational hypertension, gestational diabetes and other diseases during pregnancy is greatly increased in women over 35 years of age, and the risk of chromosomal abnormalities and malformations in the fetus will also increase accordingly. In conclusion, it is recommended that women of advanced maternal age should undergo regular prenatal checkups during pregnancy, so that abnormalities can be detected as early as possible and targeted treatment can be carried out.
