What Is an Ectopic Pregnancy?
An ectopic pregnancy occurs when a fertilized egg implants and begins developing somewhere other than the uterus. In a typical pregnancy, the fertilized egg travels through the fallopian tube and implants in the lining of the uterus, where the baby can grow and develop. However, with an ectopic pregnancy, the fertilized egg implants outside the uterus, most commonly in one of the fallopian tubes.
More than 90% of ectopic pregnancies occur in a fallopian tube. In rarer cases, implantation can occur in the ovary, cervix, abdominal cavity, or another location outside the uterus.
Unfortunately, an ectopic pregnancy cannot develop into a healthy pregnancy. The uterus is uniquely designed to support a growing baby, while other structures in the body cannot accommodate that growth. As the pregnancy develops, it can cause the surrounding tissue or fallopian tube to rupture, resulting in potentially life-threatening internal bleeding.
What Causes an Ectopic Pregnancy?
There is not always a clear explanation for why an ectopic pregnancy occurs. In many cases, something interferes with the fertilized egg's normal journey through the fallopian tube, causing it to implant before reaching the uterus.
Several factors can increase the likelihood of an ectopic pregnancy, including:
A previous ectopic pregnancy.
Previous surgery involving the fallopian tubes or reproductive organs.
Pelvic inflammatory disease or certain sexually transmitted infections.
Endometriosis.
A history of infertility or fertility treatments.
Smoking.
However, having none of these risk factors does not eliminate the possibility of an ectopic pregnancy. Many women who experience one have no known risk factors.
What Are the Symptoms of an Ectopic Pregnancy?
In the beginning, an ectopic pregnancy may feel very similar to a typical pregnancy. A woman may experience a missed period, breast tenderness, nausea, or other early pregnancy symptoms.
As the pregnancy progresses, additional symptoms may develop, including:
Pain in the lower abdomen or pelvis, particularly on one side.
Vaginal bleeding or spotting that differs from a normal menstrual period.
Lower back pain.
Cramping or discomfort in the pelvic region.
MEDICAL EMERGENCY
More serious symptoms can develop if the fallopian tube ruptures. These include sudden and severe abdominal pain, shoulder pain, dizziness, weakness, or fainting.
A ruptured ectopic pregnancy can cause severe internal bleeding and become life-threatening. Anyone experiencing sudden, severe abdominal pain, shoulder pain, or fainting while pregnant or possibly pregnant should seek emergency medical attention immediately.
It is important to remember that not every woman experiences noticeable symptoms. Some ectopic pregnancies are discovered during routine early pregnancy examinations.
When Does an Ectopic Pregnancy Usually Occur?
Ectopic pregnancies are generally detected during the first trimester, most commonly between the fourth and twelfth weeks of pregnancy. Some women discover the condition after experiencing unusual bleeding or abdominal pain. Others may not realize anything is wrong until an ultrasound examination reveals that the pregnancy has implanted outside the uterus.
Doctors typically use a combination of blood tests and ultrasound examinations to make a diagnosis. Blood tests measure human chorionic gonadotropin (hCG), the hormone produced during pregnancy. Monitoring these hormone levels over time can help doctors understand how a pregnancy is developing.
An ultrasound, particularly a transvaginal ultrasound, allows medical professionals to examine the uterus and surrounding reproductive organs to determine where the pregnancy is located.
Early diagnosis is especially important because it allows doctors to determine the safest treatment before a potentially life-threatening rupture occurs.
Is Treating an Ectopic Pregnancy Considered an Abortion?
This is an important question, particularly for women who want to understand the difference between treating a pregnancy complication and intentionally ending a healthy pregnancy.
An ectopic pregnancy is fundamentally different from a typical pregnancy. The fertilized egg has implanted somewhere that cannot support the development of a baby. Unfortunately, there is no medical procedure that can relocate the pregnancy into the uterus, and the pregnancy cannot survive in its abnormal location.
Treatment is necessary to protect the mother's life and prevent serious complications. The terminology surrounding ectopic pregnancy treatment can sometimes be confusing. In broad medical terminology, ending an ectopic pregnancy can fall under the definition of induced abortion because the treatment intentionally ends the pregnancy. However, the medical circumstances and purpose of treatment are distinct from an elective abortion that ends a viable pregnancy.
The goal of ectopic pregnancy treatment is to address the dangerous implantation, prevent further injury, and protect the mother's life. It is not a situation in which a healthy pregnancy can be preserved by simply allowing it to continue.
How Is an Ectopic Pregnancy Treated?
An ectopic pregnancy cannot safely continue, so medical treatment is necessary. The appropriate approach depends on several factors, including the location and size of the pregnancy, the woman's symptoms, hormone levels, and whether the fallopian tube has ruptured.
There are three primary approaches to managing an ectopic pregnancy:
1. Expectant Management (Careful Monitoring)
In very rare cases, particularly when the pregnancy is very small and hormone levels are already declining, doctors may recommend careful monitoring rather than immediate medication or surgery.
This approach involves regular blood tests to ensure pregnancy hormone levels continue to decrease. The body may naturally absorb the pregnancy tissue over time. However, this option is only appropriate in carefully selected situations. There is still a risk of rupture, so close medical supervision is essential.
2. Medication (Methotrexate)
When an ectopic pregnancy is detected early and has not ruptured, doctors may recommend a medication called methotrexate.
Methotrexate works by stopping rapidly dividing cells from growing, preventing the ectopic pregnancy from developing further. The body then gradually absorbs the pregnancy tissue.
The medication is typically administered through an injection, and the woman must return for follow-up blood tests to ensure pregnancy hormone levels are decreasing appropriately.
Additional medication or surgery may be necessary if the initial treatment is unsuccessful.
3. Surgery
If the fallopian tube has ruptured, or if medication is not an appropriate option, surgery may be necessary. In many cases, surgeons use a minimally invasive procedure called laparoscopy, which involves making small incisions in the abdomen to access and remove the ectopic pregnancy. Depending on the circumstances, the surgeon may remove the pregnancy tissue while preserving the fallopian tube or remove the affected tube along with the pregnancy.
When a rupture occurs, emergency surgery is necessary to stop internal bleeding and protect the woman's life. Regardless of the treatment method, follow-up care is important to ensure the pregnancy has been fully resolved and the woman's health is recovering.
Moving Forward After an Ectopic Pregnancy
An ectopic pregnancy can be a frightening and heartbreaking experience. Even when a pregnancy cannot continue, the loss of a hoped-for child can bring significant grief.
Women who have experienced an ectopic pregnancy may also wonder whether they will be able to have children in the future. Thankfully, many women go on to have healthy pregnancies following treatment for an ectopic pregnancy. However, the likelihood of another ectopic pregnancy is higher, making early medical evaluation especially important in future pregnancies.
