A woman who becomes pregnant at the age of 35 is an “advanced maternal age” and a “high-risk pregnancy” with a higher risk of pregnancy. During pregnancy, the chances of hypertension, gestational diabetes and other complications are higher, and the chances of a difficult delivery increase. The specific risks are as follows: 1. Affect the quality of pregnancy: the later a woman is pregnant and gives birth, the more her body’s egg cells will be affected by various rays and harmful substances, and the quality of her eggs will decline, making her eggs prone to chromosomal abnormalities, and the chances of mutations in her genetic material will increase, which will increase the probability of having a deformed child; 2. Pregnancy complications: 35-year-old women may increase their chances of developing diseases during pregnancy , such as diabetes, hypertension, placenta previa, etc. If a pregnant woman suffers from gestational diabetes, not only will she increase the risk of ketoacidosis, the fetus will also increase the risk of disease, malformation, premature birth or even death; 3, labor difficulties: the older a woman is, the pelvis and ligament function will gradually degenerate, the uterine contraction force may also be relatively weak, and weak contractions will cause prolonged labor, resulting in fetal distress caused by obstructed labor. In order to detect hyperemesis in a timely manner, women of 35 years of age should shorten the interval between maternity checkups and pay special attention to blood pressure and urine tests. At the same time, it is better to be admitted to the hospital for delivery a few days to ten days earlier than the average pregnant woman to ensure a safe delivery.
