How is ectopic pregnancy caused?

summary

In some cases, the fertilized egg is implanted in the fallopian tube, ovary, abdominal cavity and cervix, and becomes ectopic pregnancy, but usually we say ectopic pregnancy refers to ectopic pregnancy of fallopian tube. How is ectopic pregnancy caused? Now let's look at the reasons.

How is ectopic pregnancy caused?

Reason 1: with the continuous change of traditional ideas, premarital sex leads to abortion is becoming more and more common, repeated abortion is easy to cause ectopic pregnancy. At present, the incidence of ectopic pregnancy has increased 5-6 times compared with the 1980s. The more times of abortion, the greater the probability of ectopic pregnancy. Therefore, regardless of whether childbearing, women should do a good job of contraception, to prevent the attack of ectopic pregnancy.

Reason 2: chronic pelvic inflammatory disease, especially salpingitis is another important factor of ectopic pregnancy, women must not ignore this common gynecological disease. Because salpingitis can make its lumen become narrow, it is difficult for fertilized eggs to enter the uterine cavity, so they have to "camp" in the fallopian tube or ovary.

Reason 3: women with a history of ectopic pregnancy are more likely to have recurrent ectopic pregnancy, but interestingly, recurrent ectopic pregnancy usually occurs in the contralateral fallopian tube. Therefore, once again stressed that women who are not ready to have a baby must do a good job of contraception.

matters needing attention

According to investigation and statistics, about 1 / 3 of ectopic pregnancy patients are in pre shock or shock state when they are admitted to hospital. The severity of shock depends on the amount of internal bleeding and the speed of blood loss, which is not proportional to the amount of vaginal bleeding. In the case of tubal ectopic pregnancy (a section of fallopian tube in the uterine wall), due to the uterine muscle around the lumen, the fetus does not rupture until 3-4 months of development. This is the confluence site of uterine and ovarian blood vessels, which is rich in blood vessels. Once ruptured, a large number of intra-abdominal bleeding will occur in a very short time. If not rescued quickly, it will be life-threatening.
