How is an extrauterine pregnancy occurring?
Many pre-existing conditions and other factors increase the risk for an EUG. These include the inflammation of the ovary and fallopian tubes (pelvic inflammatory disease), for example due to venereal diseases such as chlamydia, which may cause damage to the fine cilia (which "drive" the egg in the fallopian tube) or cause gluing of the fallopian tubes "caught" the folds or stuck - by a constriction - stuck.
Other causes of extrauterine pregnancy
Sometimes the fallopian tubes are too long, have another congenital malformation or their muscles are not functioning properly, so the fertilized egg also has difficulty reaching the uterus in time. Even premature abortions, abortions or operations on the uterus or in the abdominal cavity complicate the migration of the egg, especially through adhesions.
It is also discussed that possibly the egg itself has a regulatory disorder and so very slowly or conversely wanders very fast and so does not remain in the uterus, but explored from there still the other fallopian tube.
In addition, hormonal imbalances or treatments, as well as an intrauterine pessary ("spiral") are a possible cause of pregnancy outside the uterus, and smoking, the frequent use of vaginal douching, early sexual intercourse, and frequently-changing sexual partners are suspected of increasing the risk of EUG,
If an extrauterine pregnancy has already occurred, the risk of reoccurring an ectopic pregnancy increases to 10-15%!
Incidentally, it can also lead to a so-called heterotopic pregnancy in which a normal and an extrauterine pregnancy are present at the same time. Here is the danger that the latter is not recognized and therefore complications, especially high. The frequency is quite low, but has increased in recent years in the train of reproductive medicine as an aid in unmet need for children.
How is the disease expressed?
Many ectopic pregnancies die at an early stage and the fruit is rejected unnoticed. In the other cases, the embryo dies after about 2 weeks and is usually repelled into the free abdominal cavity (tubal abortion, in 90%) and absorbed there, or the growing fruit causes tearing of the fallopian tube (tubal rupture, 10%) with life-threatening internal bleeding. Even if the egg has settled in other places, anything from unnoticed discharge to dangerous bleeding can occur.
Dismissal pregnancy in unrecognized cases is possible, but very rare. Signs of extrauterine pregnancy (known or unrecognized pregnancy) are:
- Possibly. Spotting, rare increased vaginal bleeding (usually after the period has initially stopped).
- Rather one-sided, usually increasing abdominal pains, which are convulsive or labor-like (in Tubarabort) or sudden onset of pain that resembles the feeling that something is tearing (in case of tube rupture).
- Sudden abdominal pain, touch and hard abdomen, nausea, weakness, pulse turf, severely impaired general condition and other symptoms that indicate an acute abdomen, as a sign that bleeding has occurred in the abdominal cavity (eg by tube rupture). This can lead to irritation of the diaphragm and shoulder pain.
