5 causes of ectopic pregnancy

Ectopic pregnancy means that the embryo begins to grow on the wall of the fallopian tube without reaching the uterus. Due to the rapid development of the embryo, it will implant into the wall of the fallopian tube to absorb nutrients and grow rapidly, affecting the uterus and other organs in the abdominal cavity, causing pain to the pregnant woman. The causes of ectopic pregnancy are as follows:

Abnormal fallopian tubes

There are a lot of villi inside the fallopian tube, which are responsible for transporting the eggs discharged from the ovaries to the uterus. If these villi do not function properly, it will lead to the possibility of ectopic pregnancy. Fallopian tube surgery or congenital fallopian tube stenosis and atresia may cause these villi to not function properly.

Fallopian tube surgery

Fallopian tube surgery can lead to ectopic pregnancy, such as the common fallopian tube ligation or the surgery of releasing the fallopian tube after ligation, which may cause damage to the chorionic villus tissue. Therefore, patients who undergo fallopian tube surgery due to ectopic pregnancy will have a relatively increased risk of ectopic pregnancy next time.

Pelvic inflammatory disease

If a woman suffers from pelvic inflammatory disease, it may also cause ectopic pregnancy. The reason is that pelvic inflammation will accumulate a lot of scar tissue in the fallopian tubes, which may cause blockage of the fallopian tube villi and tube walls.

Abnormal hormone levels

Excessive estrogen and progesterone are one of the reasons for the increase of ectopic pregnancy. In the early stages of pregnancy, these hormones should be reduced appropriately to stimulate the egg to slowly pass through the fallopian tube to the uterus. If these hormones are too high, it will cause the fertilized egg to stay in the fallopian tube, causing ectopic pregnancy.

Other factors

Age factors are also a cause of ectopic pregnancy. Older mothers are more likely to have ectopic pregnancy. The relationship between pregnant women with smoking habits and ectopic pregnancy is also being studied, but there is still no official report.
