pregnant woman
Older women are at great risk of getting pregnant. Common diseases include hypertensive disorder complicating pregnancy, gestational diabetes mellitus, intrauterine death, placental abruption and placenta previa. Women who are pregnant over 37 years old are called elderly pregnant women. Because the probability of various pregnancy complications over the age of 37 will increase significantly. The most common is hypertensive disorder complicating pregnancy. Pregnancy induced hypertension can lead to intrauterine growth retardation, intrauterine death and placental abruption. However, due to the increase of age, the insulin sensitivity in the body decreases, and gestational diabetes mellitus is more likely to occur. Once gestational diabetes occurs, the possibility of fetal macrosomia will increase significantly. For pregnant women, the probability of dystocia is also relatively high. Moreover, the older you get, the more likely sperm and eggs will be deformed, and fertilized eggs may have early embryo stagnation, fetal malformation and intrauterine stillbirth in the third trimester of pregnancy.
