What are the causes of ectopic pregnancy? I don't know when it started. Ectopic pregnancy seems to be more and more common. Ectopic pregnancy is a nightmare for women. The only way to solve ectopic pregnancy is to have abortion as soon as possible, otherwise it will have a great influence on women. Come with me to see the causes of ectopic pregnancy.
What are the causes of ectopic pregnancy? 1 1, tubal inflammation.
It can be divided into tubal mucositis and peritubal inflammation, both of which are common causes of tubal pregnancy. Severe oviduct mucositis can lead to complete obstruction of lumen and infertility, while mild oviduct mucositis and ciliary defects can affect the operation of fertilized eggs and lead to implantation there. Salpingitis caused by gonorrhea and chlamydia trachomatis often involves mucosa, and abortion or postpartum infection often causes salpingitis.
2. Tubal surgery
Tubal recanalization or fistula may lead to tubal pregnancy after tubal sterilization, especially laparoscopic electrocoagulation tubal sterilization and silicone ring. Accept tubal separation and adhesion due to infertility. Tuboplasty, such as tubal anastomosis. The incidence of the second tubal pregnancy was 10% ~ 20%.
3. Tubal dysplasia or abnormal function.
Dysplasia of fallopian tubes is often characterized by too long fallopian tubes, muscular dysplasia and lack of mucocilia. Others have double fallopian tubes. Diverticula or parasol may be the cause of tubal pregnancy. If the secretion of estrogen and progesterone is abnormal, it can affect the normal operation of fertilized eggs. In addition, mental factors can also cause tubal spasm and abnormal peristalsis, and interfere with the transportation of fertilized eggs.
4. fertilized eggs can swim
The egg is fertilized in one fallopian tube, and the fertilized egg enters the opposite fallopian tube through the uterine cavity or abdominal cavity, which is called fertilized egg migration. If the migration time is too long, the fertilized egg will grow, and then it can be implanted into the contralateral fallopian tube to form tubal pregnancy.
What are the causes of ectopic pregnancy? 2 1. Women who have had multiple abortions.
At present, the incidence of ectopic pregnancy is 5-6 times higher than that in 1980s. The more people have abortions, the greater the chance of ectopic pregnancy. Therefore, regardless of whether they give birth or not, women should do a good job of contraception to prevent the occurrence of ectopic pregnancy.
2. Chronic gynecological inflammation
Appendicitis. Pelvic inflammatory disease, especially salpingitis, is another important factor of ectopic pregnancy, and women must not ignore this common gynecological disease. Because salpingitis can narrow the lumen, it is difficult for fertilized eggs to enter the uterine cavity, so they have to camp in the fallopian tube or ovary. The fallopian tubes of women who recanalize after tubal ligation are not as smooth as before, and the recanalization place is narrow, so it is easy to prevent pregnant eggs from staying in the narrow place to settle down.
3, the use of ovulation drugs or IVF.
Because on the third day, when the fertilized egg is put into the uterine cavity, it takes 3 ~ 4 days to find a suitable "soil". During this period, due to endometritis and other factors, the condition of uterine cavity may be destroyed, and fertilized eggs will run to the fallopian tube to live, causing ectopic pregnancy.
4. Women with a history of ectopic pregnancy
If a woman who has suffered from ectopic pregnancy is ready to get pregnant again, but the cause of ectopic pregnancy has not been found out and eliminated before, then ectopic pregnancy is likely to occur after this pregnancy.
5. The risk of ectopic pregnancy will also increase for women who have undergone abdominal surgery.
In addition, appendicitis perforation is also a high risk factor for ectopic pregnancy, and appendectomy will increase the risk of ectopic pregnancy by 1.8 times.
6. Women with intrauterine devices
Because the upper ring will affect the "destination" of fertilized eggs, once pregnant, fertilized eggs are likely to "camp" outside the uterine cavity (the common parts are fallopian tubes and ovaries), which is ectopic pregnancy.
7. Smokers and drinkers
Because nicotine in tobacco can change the ciliary movement of fallopian tubes. In addition, the study found that women who drink for a long time or suddenly drink a lot are prone to tubal stenosis, low cilia swing function and poor tubal wall peristalsis, which is not conducive to the settlement of fertilized eggs in the uterus.
8. Improper choice of contraceptive methods
Birth control pills can affect women. The level of progesterone in turn affects the peristalsis of the tubal wall. Ciliary activity and epithelial cell secretion. If the hormone is out of balance, it will affect the transportation of fertilized eggs and lead to tubal pregnancy.
9, suffering from endometriosis
Endometriosis caused by menstrual reflux and other reasons is a high risk factor for ectopic pregnancy. Especially when endometriosis is in the interstitial part of fallopian tube, it is very likely that fertilized eggs will camp here.
10, ovarian cyst
Women suffering from hysteromyoma or ovarian cyst at the bottom of the uterus, because of the extrusion of the tumor, the uterus and fallopian tubes shift and change their morphology, which hinders the normal implantation of fertilized eggs and also causes ectopic pregnancy.
