What are the causes of ectopic pregnancy?

According to surveys, 90% of ectopic pregnancies occur in the human fallopian tube. The fertilized egg in the fallopian tube cannot develop into a normal fetus, which will also affect the life safety of the pregnant woman. In recent years, the incidence of ectopic pregnancies has been very high, usually 10 out of 100 pregnant women have ectopic pregnancies. So, what are the causes of ectopic pregnancy? How to better prevent ectopic pregnancy with gestational sac? The following is a detailed introduction by experts on this issue.

According to hospital clinical statistics, the causes of ectopic pregnancy are as follows:

Repeated abortions: The incidence of ectopic pregnancy has increased exponentially, which is mainly related to the fact that some women have abortions without restraint. Frequent abortions can cause trauma to the endometrium, making it difficult for the embryo to implant in the uterus and so it will be transferred to other places to settle down.

Fallopian tube inflammation: People with acute or chronic fallopian tube inflammation have congestion and edema of the fallopian tube mucosa, adhesion of the mucosal wall, which causes the lumen to narrow and become obstructed, and the peristalsis of the smooth muscle of the tube wall to weaken, which is not conducive to the movement of the fertilized egg and leads to ectopic pregnancy.

Endometriosis: Endometriosis caused by various reasons such as retrograde menstruation is a high-risk factor for ectopic pregnancy.

Clinically, there are quite a number of patients who are only found to have uterine fibroids after they become pregnant, just like the case of Ms. Chen in this case. At this time, expectant mothers are often very nervous: the uterus is the safe haven for the baby to survive. Now a tumor suddenly grows. Can the pregnancy continue? Will it lead to miscarriage? The worries of expectant mothers are not unreasonable, because uterine fibroids do have an impact on pregnancy:

In the early stages of pregnancy, due to the presence of fibroids, it is not conducive to the implantation and growth and development of the fertilized egg. The incidence of miscarriage is 2 to 3 times that of pregnant women without fibroids, and it is often an incomplete miscarriage, resulting in more bleeding.

In the middle and late stages of pregnancy, large intramural fibroids or submucosal fibroids can hinder the movement of the fetus in the uterus and cause malposition of the fetus, increased incidence of breech presentation and transverse presentation, and thus increased cesarean section rate. Moreover, due to deformation of the uterine cavity or mechanical obstruction of the development of the placenta and fetus, premature birth may easily occur.

During delivery, fibroids affect the normal contraction of the uterus, causing uterine atony and prolonging the labor process. Fibroids embedded in the pelvic cavity, such as cervical fibroids and giant lower uterine fibroids, can block the birth canal and cause dystocia.

The above is a complete introduction to the causes of ectopic pregnancy. From the above introduction, it can be seen that there are many reasons that lead to ectopic pregnancy, and ectopic pregnancy has a great impact on women’s physical health. Severe cases may endanger life safety. Therefore, everyone must do a good job of prevention in daily life to prevent the occurrence of ectopic pregnancy. Once ectopic pregnancy occurs, it must be actively treated.
