While tubal pregnancies are not very common, they are life-threatening and require urgent medical attention and treatment when they do occur.
During the normal course of pregnancy, fertilized eggs attach to the
lining of the uterus where they grow until the time of delivery. However,
there are instances, cumulatively referred to as ectopic
pregnancies, or eccyesis, in which the egg is implanted at a site
outside the uterus. Among these, the most common, comprising 80% of all
ectopic pregnancies are tubal pregnancies, in which the fertilized egg is
implanted in the fallopian or uterine tubes.
While tubal pregnancies are not very common, they are life-threatening
and require urgent medical attention and treatment when they do occur.

Signs and Symptoms of Tubal Pregnancy
Vaginal bleeding – heavy vaginal bleeding occurs due to the
weight of the growing embryo and is often accompanied by abdominal pain.
Body pain – most commonly, women with tubal pregnancies experience a sharp
and cramping pain very similar to menstrual cramps in the abdomen. Typically,
this pain is unilateral, or one-sided. Furthermore, in some cases, this pain
can spread to the shoulder, the neck, and even the rectum. However, shoulder,
neck, and rectal pain may also occur independent of abdominal pain.
Gastrointestinal problems – tubal pregnancies may cause
nausea, vomiting, and/or diarrhea.
Dizziness, weakness, and fainting
Risk Factors for Tubal Pregnancy
Factors that increase the risk of ectopic
pregnancies, including tubal pregnancies, typically cause fallopian
tube damage and include:
Smoking – women who smoke have higher chances of having a tubal pregnancy. According
to gynaecology, the fallopian tube of the pregnant woman tends to get damaged
due to smoking which leads to the chances of ectopic pregnancy.
Maternal Age – the risk of PID typically increases with increasing age and most
commonly occurs in pregnant women between the ages of 35 and 45.
Inflammatory Disease (PID) – PID,
or salpingitis, is an infection of the pelvis including the fallopian tubes
which increases the risk of tubal pregnancy by causing fallopian tube damage.
Often, it occurs due to gonorrhoea or chlamydia.
Endometriosis and adenomyosis– these conditions which involve
abnormal growth of endometrial tissue outside of the uterus (specifically, in
the myometrium in the case of adenomyosis) increase the risk of tubal pregnancy
by causing scarring around the fallopian tube and, thereby, “trapping” the
fertilized egg in the fallopian tubes by blocking its path of exit.
Prior tubal pregnancy – the risk of having a tubal
pregnancy is also increased if one has experienced one before. This is
logical as scarring that was present during an earlier pregnancy would still be
present during a later pregnancy.
Preventing Tubal Pregnancy
While tubal pregnancies, themselves, cannot be prevented, the risk of
serious complications can be decreased by careful monitoring on the part of
your healthcare providers, leading to early diagnosis and treatment. For
example, should you possess risk factors for tubal pregnancy, be sure to confer
with your physician and plan to carefully monitor your pregnancy.
Furthermore, as Pelvic
Inflammatory Disease (PID), a risk factor, is caused by
sexually transmitted diseases (STDs), you can decrease your risk of
experiencing a tubal pregnancy by engaging in safer sex practices such as using
condoms to prevent the acquisition and transmission of disease.
Additionally, if you are a smoker, another risk factor, you can decrease your
risk by making the decision to quit.
