What are the causes of ectopic pregnancy?

After gynecological inflammation or abortion, the body's own defense mechanism decreases, leading to inflammation of the tissues around the fallopian tubes. It can easily cause ectopic pregnancy. For those who have repeated abortions, the more times they get pregnant, the greater the possibility of ectopic pregnancy. Regular use of birth control pills can also increase the possibility of ectopic pregnancy. Failure to take effective contraceptive measures can also increase the risk of ectopic pregnancy. Want to know what causes ectopic pregnancy?

1. Reproductive tract infection

Gynecological inflammations, such as vaginitis and cervicitis, may ascend to infect the fallopian tubes and cause fallopian tube inflammation. After an abortion, the body's own defense mechanism is affected, and the fallopian tubes are susceptible to bacterial infection, leading to inflammation of the tissues surrounding the fallopian tubes. For women who have repeated abortions, the more times they become pregnant, the greater the possibility of ectopic pregnancy. Studies have shown that pelvic inflammatory disease can also increase the risk of ectopic pregnancy by 2.7 times.

2. Some surgical procedures

The cesarean section rate is now on the rise, and ectopic pregnancies occurring in uterine scars are also increasing. In addition, appendicitis perforation is also a high-risk factor for ectopic pregnancy, and appendectomy increases the risk of ectopic pregnancy by 1.8 times.

3. Improper contraceptive methods

Contraceptive pills affect the levels of estrogen and progesterone, which in turn affects the peristalsis of the fallopian tube wall, ciliary activity, and secretion of epithelial cells. If the hormones are out of balance, it will affect the delivery of the fertilized egg and cause fallopian tube pregnancy. Some women lack self-protection awareness and do not have long-term contraceptive measures. The abuse of contraceptives will increase the risk of ectopic pregnancy.

4. Bad living habits

Studies have shown that nicotine and alcohol can affect the movement of fallopian tube cilia and induce ectopic pregnancy. According to statistics, the incidence rate among smokers is 1.5-4 times higher than that among non-smokers.
