Is ectopic pregnancy caused by blocked fallopian tubes?

An ectopic pregnancy is when the fertilized egg begins to develop before reaching the uterus. An ectopic pregnancy will not result in a successful pregnancy. On the contrary, it will cause great harm to the woman's body and mind. Some ectopic pregnancies are not discovered in time and are not detected until they develop to a certain state. In severe cases, the woman may face the risk of having her uterus removed. Moreover, ectopic pregnancy is not necessarily caused by fallopian tube blockage and may be related to these factors.

What causes ectopic pregnancy?

1. Chronic pelvic inflammatory disease: Chronic pelvic inflammatory disease, especially salpingitis, is another important factor in the occurrence of ectopic pregnancy. Because salpingitis can cause the lumen of the tube to become narrow, it is difficult for the fertilized egg to enter the uterine cavity, so it has to "set up camp" in the fallopian tube or ovary.

2. History of ectopic pregnancy: Women with a history of ectopic pregnancy are very likely to have another ectopic pregnancy, but what is interesting is that the next ectopic pregnancy usually occurs in the contralateral fallopian tube. Therefore, we emphasize once again that women who are not planning to have a baby must take good contraceptive measures.

3. Repeated abortions: With the continuous change of traditional concepts, abortions caused by premarital sex are becoming more and more common, and repeated abortions can easily lead to ectopic pregnancy. The more abortions you have, the greater the chance of an ectopic pregnancy. Therefore, regardless of whether they are pregnant or not, women should take good contraceptive measures to prevent ectopic pregnancies.

4. Fallopian tube inflammation: About 60% of patients with fallopian tube pregnancy have a history of fallopian tube inflammation. Recurrent chronic salpingitis causes adhesion of the fallopian tube mucosal folds, narrowing of the lumen, damage of the cilia, or twisting of the fallopian tube due to adhesion of the inflammation to the surrounding tissues, making it unable to move normally. All of these can hinder the normal operation of the fertilized egg, preventing the fertilized egg from reaching the uterine cavity as scheduled and implanting in the fallopian tube.

5. Migration of the fertilized egg: One ovary ovulates, but after fertilization it migrates through the uterine cavity or abdominal cavity to the opposite fallopian tube, which is called migration of the fertilized egg. As the fertilized egg gradually grows during the migration process, when it cannot pass through the fallopian tube, that is, when it implants in the fallopian tube, tubal pregnancy occurs. Women with pelvic endometriosis or wearing an intrauterine device are also at increased risk of tubal pregnancy.
