High risk pregnancy is a condition that occurs during pregnancy for pregnant women. Pregnant women can experience many situations during pregnancy, and some lucky expectant mothers can give birth to their babies smoothly and healthily. However, there are also many exceptions, as each person's physical condition results in different pregnancies. So, the existing situation is also different. What is the category of high-risk pregnancy?
Category of high-risk pregnancies
Pregnancy, a physiological term. Also known as the pregnancy period. The period of time between a woman's fertilization and the delivery of the fetus. For ease of calculation, pregnancy usually starts from the first day of the last menstrual period, and full-term pregnancy is approximately 280 days (40 weeks). High risk pregnancy directly endangers the health and safety of both the mother and the fetus.
There are many situations of high-risk pregnancy, mainly including the following: pregnant women under 16 years old or over 35 years old; Having a history of habitual miscarriage, premature birth, stillbirth, stillbirth, and abnormal fertility in the past; During pregnancy, there may be abnormal conditions such as placenta previa, placental abruption, polyhydramnios or oligohydramnios, fetal malposition, post term pregnancy, abnormal fetal development, macrosomia, gestational hypertension syndrome, pelvic stenosis or malformation; Pregnant women with heart disease, chronic nephritis, diabetes, acute infectious hepatitis, tuberculosis, severe anemia and other pregnancy complications; Pregnant women who have taken drugs that have an impact on the fetus, have been exposed to harmful substances, or have been exposed to adverse factors such as radiation and viral infections.
Pathological causes of high-risk pregnancy
High risk pregnancy often results in poor communication between the uterus and the other side, leading to two possible ways of fertilization in the residual horn uterus: one is for sperm to migrate outside the contralateral fallopian tube and combine with the egg in the affected fallopian tube, entering the residual horn; One is that the fertilized egg migrates through the contralateral fallopian tube to the affected fallopian tube and enters the residual horn for implantation and development. High risk pregnancy with residual horn uterine muscle wall often results in underdevelopment, which cannot withstand fetal growth and development. Most cases occur between 14-20 weeks of pregnancy with complete or incomplete rupture of the muscle layer, causing severe internal bleeding. The symptoms are similar to those of tubal interstitial pregnancy rupture.
Having understood the scope of high-risk pregnancy, expectant mothers need to find the right timing. Age is also a category of high-risk pregnancies. Expectant mothers can give birth to their own babies at the best time to avoid increasing the risk of conception. We can also learn some small knowledge about the pathological causes of high-risk pregnancy, which expectant mothers can understand.
