4hw.com.cn: for many young people now, they will not have children very early, so they will choose painless abortion after pregnancy. However, due to family and other reasons, they will still have a child. Then the problem comes. How long can they be pregnant after painless abortion? How much is the chance of second pregnancy of painless abortion? Follow Xiaobian to have a look!
After the abortion, although the function of fertility will be restored soon, it is not appropriate to conceive at this time, because after the abortion, the genital tubes such as uterus and ovaries and the body have a slow recovery process. In this period of time, the normal level can be restored only by slow recuperation. So, how long can you get pregnant again after abortion surgery?
After painless abortion operation, ovulation function recovers quickly. Many women can recover ovulation function only about 22 days. At this time, if they do not pay attention to contraception, they may be pregnant again.
According to the research, the painless abortion history is related to the preterm delivery of second pregnancy. The risk of preterm delivery (more than 28 weeks and less than 32 weeks) in the early stage of second pregnancy is higher than that in the medium preterm delivery (more than 32 weeks and less than 34 weeks), and the history of artificial abortion is significantly related to the spontaneous preterm delivery, and has a dose-response relationship. It is further pointed out that the history of two or more artificial abortions is closely related to the indicative preterm delivery It may be related to infection and mechanical injury. The history of induced abortion can increase the incidence of pregnancy complications, such as premonitory abortion, placenta previa, premature rupture of membranes, and fetal distress, indirectly increase the risk of premature delivery, and increase the incidence of premature delivery or iatrogenic premature delivery.
1. After induced abortion, the risk of premonitory abortion is significantly increased. The main reason may be induced abortion, especially surgical abortion, which is a kind of traumatic operation. Suction and curettage of uterine cavity can cause endometrial damage. Some patients have secondary infection after operation, resulting in endometritis. Endometrial damage can cause decidual dysplasia during the second pregnancy. As a pregnancy microenvironment, decidua develops The status is closely related to the success of pregnancy.
2. Painless abortion can increase the incidence of placenta previa in the second pregnancy, and the more times, the shorter the interval from the second pregnancy, the higher the incidence of placenta previa in the second pregnancy. The surgical abortion group is higher than the drug abortion group, but the difference between the drug abortion group and the control group is not significant. The possible mechanism of the increased risk is that, in the process of operation abortion, due to multiple uterine aspiration or improper operation, especially high negative pressure suction pressure, it can damage the endometrium, such as involving the basal layer of the decidua fundus, so that the decidua fundus is underdeveloped and the blood supply is insufficient during the second pregnancy, while the placenta expands its area to the lower segment of the uterus or covers the cervix in order to obtain sufficient nutrition Inner mouth, forming placenta previa.
Whether painless abortion or premature delivery, have entered a pregnancy process, as long as the first pregnancy, all organs of the body will have a series of corresponding changes to adapt to pregnancy, such as the uterus gradually increased and thinned; the isthmus of the uterus gradually stretched and thinned, expanded into a part of the uterus; the ovaries increased, stop ovulation; breasts increased, glandular tube development; The burden and function of heart and lung are enhanced, the output of heart blood is increased, the blood pressure is changed, the circulating blood volume is increased, and the endocrine system is changed.
The body needs a long period of adjustment to fully recover this series of changes. Pregnancy is a complex and precise physiological process which needs coordination and cooperation of many aspects and systems. Any uncoordinated preparation will affect the process and quality of pregnancy. In the body, especially in the ovarian function, endometrium, hormones and endocrine adjustment before the pregnancy, egg quality, fertilized egg implantation and embryo development may not be well guaranteed.
Women who have a caesarean section need at least two years to conceive. Because the cesarean section causes trauma and damage to the uterus, scar tissue is left on the uterine wall after the incision of the uterus. It takes a long time for the function of endometrium to recover and scar tissue to repair, and its elasticity, toughness and thickness are quite different from those of normal uterine muscles. When the scar of the uterus is not completely repaired, the normal contractile rhythm of the uterus is out of order due to the above differences. During the process of the enlargement and / or contraction of the uterus, the muscle fibers are prone to rupture, which is dangerous for the rupture of the uterus.
At the same time, if the function of uterus and the repair of endometrium are not complete, it will not provide a good growth environment for the implantation of fertilized eggs and the development of fetus. If the pregnancy and delivery are too early after operation, a series of serious complications and consequences, such as discordant uterine contraction, uterine rupture and fetal death, are likely to occur, which may threaten the lives of mothers and infants.
