What impact will artificial abortion have on the next pregnancy?

Artificial abortion, especially repeated artificial abortion, will have a certain impact on the next pregnancy, which is manifested in the following aspects:

1. Increased late miscarriage and premature birth rates. The most common complication after artificial abortion is cervical injury. Damage to the internal os is often not discovered, and in subsequent pregnancies, internal cervical incompetence occurs, causing premature or late miscarriage, and a high incidence of premature rupture of membranes.

2. Increased perinatal mortality. The high perinatal mortality is due to increased neonatal mortality and stillbirth rates. Some artificial abortions damage the endometrium and myometrium, so placental blood circulation disorders may occur in the next pregnancy, causing placental insufficiency, leading to fetal hypoxia and slow growth, so stillbirth and neonatal mortality rates increase. In addition, the number of premature babies increases, and the neonatal mortality rate also increases.

3. High rates of antepartum and postpartum hemorrhage. Due to the disorder of placental blood circulation, the placenta is larger than normal and attached at a lower position, so the rate of antepartum hemorrhage is high. The placenta may be adhered after delivery, which may prolong the separation time or require manual separation. It may also be incompletely separated and cause placental residue, which can increase the incidence of postpartum hemorrhage.

4. Impact on neonatal hemolytic disease. When artificial abortion is performed in early pregnancy, fetal red blood cells can enter the maternal blood circulation through the open blood vessels in the uterine wall. If the mother and the child have Rh blood type incompatibility, as long as 0.25 ml of fetal blood enters the mother's body, it may cause the mother to produce Rh antibodies, and neonatal hemolytic disease may occur in the next pregnancy. Neonatal hemolytic disease caused by Rh blood type incompatibility usually occurs in infants after the second pregnancy. Abortion can promote the mother's production of Rh antibodies, causing the baby in the second pregnancy to be Rh immune, resulting in neonatal hemolytic disease.

5. Increased spontaneous abortion rate in early pregnancy. Artificial abortion will increase the spontaneous abortion rate in subsequent pregnancies, and there is sufficient evidence to prove that women who have repeated artificial abortions have an increased risk of spontaneous abortion. The cause of abortion may be related to surgical complications, such as endometrial infection. In early pregnancy, due to trophoblast dysplasia or decidual inflammation, villous vascular infarction, villous edema, trophoblast ischemia and hypoxia, degeneration occurs and embryonic death occurs.

6. Increased incidence of ectopic pregnancy. The incidence of ectopic pregnancy is not directly related to surgery, but is related to surgical complications, such as endometrial infection, incomplete abortion, infected abortion, etc. These complications can lead to obstruction of the fallopian tube, resulting in obstruction of the fertilized egg transport and implantation outside the uterine cavity.
