Why does ectopic pregnancy occur?

The occurrence of ectopic pregnancy still has an impact on personal health. If it is not discovered in time, the impact will be greater. Why does ectopic pregnancy occur? There are actually many reasons, such as fallopian tube inflammation, history of fallopian tube pregnancy, multiple artificial abortions, etc., so friends who are preparing for pregnancy should pay more attention.

1. Fallopian tube inflammation. It can be divided into tubal mucositis and perisalpingitis, both of which are common causes of tubal pregnancy. Severe cases of fallopian tube mucositis can cause complete blockage of the tubal lumen and lead to infertility. The lesions of perisalpingitis are mainly in the serosa or seromuscular layer of the fallopian tube, which often causes adhesions around the fallopian tube, twisting of the fallopian tube, stenosis of the tubal lumen, and weakened peristalsis of the tubal wall muscles, affecting the movement of the fertilized egg.

2. History of tubal pregnancy. Women who have had a tubal pregnancy are more likely to have another tubal pregnancy after recovering from surgical treatment.

3. Insertion of intrauterine contraceptive device. The use of an IUD itself does not increase the incidence of ectopic pregnancy, but if a woman becomes pregnant due to IUD contraceptive failure, the chance of an ectopic pregnancy is greater.

4. Fallopian tube hypoplasia or abnormal function. Tubal dysplasia is often manifested by excessively long fallopian tubes, poor development of the muscular layer, and lack of mucociliary tissue. The function of the fallopian tube is regulated by estrogen and progesterone. If the regulation fails, it will affect the normal operation of the fertilized egg.

5. The fertilized egg wanders. When the egg is fertilized in one fallopian tube and enters the opposite fallopian tube through the uterine cavity or abdominal cavity, it is called fertilized egg migration. If the migration time is too long, the fertilized egg will grow larger and can implant in the opposite fallopian tube and form a tubal pregnancy.

6. Causes of disease. Compression from tumors around the fallopian tubes, such as uterine fibroids or ovarian tumors, sometimes affects the patency of the fallopian tube lumen, obstructing the movement of the fertilized egg. Endometriosis can increase the likelihood that a fertilized egg will implant in the fallopian tube.

7. Multiple artificial abortions. Repeated and frequent artificial abortions will cause trauma to the endometrium, making it difficult for the embryo to implant in the uterine cavity. It will then transfer to another place to implant, resulting in an ectopic pregnancy.

8. Bad living habits. Smoking, alcoholism, and taking ovulation-stimulating drugs can increase the incidence of ectopic pregnancy.
