Who is prone to prolonged pregnancy

summary

Prolonged pregnancy is mainly the time of pregnancy beyond the normal period, the fetal mortality is quite high, which is a very dangerous situation. Let's take a look at who is prone to prolonged pregnancy.

Who is prone to prolonged pregnancy

First: pregnancy reaches or exceeds 42 weeks, which is called overdue pregnancy. Its incidence rate is 5% - 12% of the total number of pregnancies. The perinatal morbidity and mortality of the fetus with prolonged pregnancy increased, and increased with the prolongation of pregnancy. The perinatal mortality was three times of the normal at 43 weeks of pregnancy.

Second, the reason for the occurrence of prolonged pregnancy is not clear. Because there are many possible factors leading to childbirth, including progesterone block, oxytocin stimulation and fetal adrenal cortical hormone secretion, any factor causing these hormone imbalance can lead to prolonged pregnancy.

Finally: therefore, prolonged pregnancy may be related to the following factors: imbalance of estrogen and progesterone; fetal malformation, such as anencephaly, may be related to insufficient secretion of fetal adrenal cortical hormone; genetic factors, etc. In the process of pregnancy, regular physical examination should be carried out to have a comprehensive understanding of the development of the fetus.

matters needing attention

Expectant mothers can also count their babies' fetal movements by themselves. If the fetal movements are less than 20 times within 12 hours, it means that the fetus is abnormal; if the fetal movements are less than 10 times, it means that the fetus is very dangerous, so they should go to the hospital immediately. If the diagnosis of prolonged pregnancy, it should be timely termination of pregnancy, to avoid the risk of maternal health.
