Understanding Ectopic Pregnancy, Its Causes And Effective Treatments


An ectopic pregnancy occurs when a fertilized egg implants and grows outside of the main cavity of the uterus. It is a potentially life-threatening condition that affects 1-2% of all pregnancies.

Quick diagnosis and treatment are essential to save the mother’s life and preserve fertility. In this article, we will discuss what an ectopic pregnancy is, what causes it, how it is diagnosed and treated, and some frequently asked questions.

What Is Ectopic Pregnancy? 

Normally, a fertilized egg travels through the fallopian tube and implants itself in the uterine lining where it continues to develop. In an ectopic pregnancy, the fertilized egg gets implanted somewhere else – usually in one of the fallopian tubes, but sometimes in the cervix, ovaries, or abdomen. As the pregnancy progresses, it starts stretching and damaging nearby organs as the ectopic mass grows. This can cause severe internal bleeding if left untreated. 

Ectopic Pregnancy - Causes - Treatments

The most common site for ectopic implantation is the fallopian tube. This accounts for 98% of ectopic pregnancies. This part of the tube is narrow and does not have enough room for a growing embryo.

A fertilized egg getting stuck here will cause the thin tubal lining to stretch and eventually rupture, causing major internal bleeding. Other less common sites are the ovary, cervix, or abdomen. Abdominal pregnancy is very rare but extremely dangerous.

An ectopic pregnancy cannot proceed normally. The embryo will not survive once the organ it has implanted in ruptures and bleeding starts. If not treated quickly, ectopic pregnancies can become life-threatening. Therefore, early detection and swift treatment are critical.

Causes Of Ectopic Pregnancy

Several risk factors increase the chances of an ectopic pregnancy:

  • Pelvic inflammatory disease – Infection and inflammation of the reproductive organs can cause scarring and damage to the fallopian tubes, preventing the fertilized egg from passing through smoothly.
  • Previous ectopic pregnancy – Having one ectopic increases the risk for another.
  • Tubal surgeries – Such as tubal ligation or tubal reconstruction surgery. The repaired tube might not work properly.
  • Smoking – Chemicals from cigarette smoking can affect tubal motility.
  • Abnormal embryo development – A problem with the developing embryo itself can impede its movement. 
  • Multiple sexual partners – Increases risk of contracting infections that cause pelvic inflammation.
  • Assisted reproductive techniques – Such as IVF where sometimes more than one embryo is placed. 
  • Use of an IUD – Changes in the uterus environment may interfere with implantation.
  • Previous abdominal or pelvic surgery – Scarring from surgeries can damage the reproductive structures. 

Thus, while the exact cause may not be known in every case, any prior condition that has caused alterations in the uterus or fallopian tubes increases susceptibility. 

How To Treat An Ectopic Pregnancy?

Doctors have to act quickly when an ectopic pregnancy is suspected. Confirmation is done through ultrasound, blood tests for hCG levels, and laparoscopy. Treatment depends on the location and development of the ectopic mass, the patient’s overall health, and the desire for fertility preservation.

Options include:

Medication – An injection of methotrexate stops the growth of the embryo. It works best when the diagnosis is made early.

Laparoscopic surgery – Using a small incision, the ectopic tissue is removed while preserving the fallopian tube if possible. 

Laparotomy – If there is extensive damage or the patient is unstable, a larger abdominal incision may be required for open surgery.

Expectant management – If the ectopic mass is small and hCG levels low, the doctor may opt for careful observation while waiting for it to resolve on its own.

Emergency surgical repair of any internal bleeding or removed reproductive organs may be required in severe cases. After losing one tube, it’s still possible to have a healthy pregnancy later with the other tube. But the chances are reduced. IVF is an option for those with low fertility prospects after ectopic surgery.


Ectopic pregnancy can be a gynecological emergency if not detected and treated promptly. All pregnant women should be screened for possible risk factors and monitored for abnormal implantation through regular ultrasounds.

While an ectopic pregnancy usually ends a woman’s hopes for that particular pregnancy, prompt diagnosis and management can save her life and preserve fertility. Public awareness and constant medical advances are key to reducing the risks associated with this potentially dangerous complication.


Q: How common are ectopic pregnancies?

A: About 1-2% of reported pregnancies are ectopic. It is the leading cause of pregnancy-related death in the first trimester.

Q: What are the symptoms of an ectopic pregnancy?

A: Symptoms include one-sided pelvic pain, vaginal bleeding, dizziness, and shoulder pain. However, it may not always produce noticeable symptoms in the early stages. 

Q: Can an ectopic pregnancy be saved? 

A: Unfortunately no. The embryo will not survive outside the uterine environment and must be removed to save the mother’s life.

Q: Does an ectopic pregnancy mean I can’t get pregnant again?

A: No, as long as the affected tube was not removed and the other one is healthy, you can conceive again, although subsequent ectopics are more likely. Discuss your options with your doctor.

Q: Do I need bed rest after ectopic surgery? 

A: Most women can resume normal activity within a week after laparoscopic treatment. Listen to your body and avoid strenuous activity while healing. Check with your doctor.
