An ectopic pregnancy is one that occurs outside of the confines of your uterus, typically when a fertilized egg implants in a location unsuitable for its growth. The most common site for ectopic pregnancy is the fallopian tube, which connects the ovaries and the uterus. Although more rarely, ectopic pregnancies can also develop in the ovary, abdominal cavity, or cervix. It’s important to understand that ectopic pregnancies cannot progress normally because only the uterus is designed to support a pregnancy.
Ectopic pregnancies can escalate to life-threatening situations, particularly when the fallopian tube ruptures, leading to a condition known as a ruptured ectopic pregnancy. This can result in severe bleeding, infection, and, in some cases, even death. A ruptured ectopic pregnancy is a medical emergency that necessitates prompt treatment by healthcare providers.
Where Does an Ectopic Pregnancy Occur?
An ectopic pregnancy occurs when a fertilized egg implants itself outside of the normal location, which is the uterus. Typically, the egg’s journey involves traveling down the fallopian tubes and attaching to the uterine wall for development. However, in an ectopic pregnancy, this implantation occurs in one of the structures along this way. The most prevalent location for such an occurrence is within the fallopian tubes, where the majority of ectopic pregnancies, around 90%, take place.
What are the symptoms of an ectopic pregnancy?
The symptoms of an ectopic pregnancy can resemble those of a typical pregnancy, particularly in the early stages. However, during an ectopic pregnancy, you may also experience the following symptoms:
- Vaginal bleeding.
- Pain in the lower abdomen, pelvis, and lower back.
- Feelings of dizziness or weakness.
In the event of a rupture in the fallopian tube, the pain and bleeding can become severe and lead to additional symptoms, which may include:
- Fainting.
- Low blood pressure (hypotension).
- Shoulder pain.
- Sensations of rectal pressure or bowel issues.
A burst in the tube can result in sudden and intense lower abdominal pain, signifying a medical emergency. It is imperative to promptly contact your healthcare provider or proceed to the emergency room without delay.
What causes an ectopic pregnancy?
Ectopic pregnancies are primarily brought about by factors that hinder or block the egg’s progression through the fallopian tube. This can occur due to the following reasons:
- Presence of scar tissue, adhesions, or inflammation resulting from previous pelvic surgery.
- Damage to the fallopian tubes is often caused by a sexually transmitted infection (STI).
- Natural irregularities in the shape of the fallopian tube from birth.
- The presence of growths that block the fallopian tube.
How is an ectopic pregnancy diagnosed?
The diagnosis of an ectopic pregnancy often occurs when individuals consult their pregnancy care provider for a routine prenatal visit, blood tests, or ultrasound. The suspicion of an ectopic pregnancy typically arises during this appointment.
To confirm the diagnosis of an ectopic pregnancy, your provider will conduct a series of tests, which may encompass a pelvic examination and pregnancy confirmation. These diagnostic procedures consist of:
- Urine Test: This test involves either providing a urine sample in your provider’s office, where a test strip is dipped into the sample, or using a test strip that you pee on.
- Blood Test: Your provider may conduct a blood test to measure the levels of human chorionic gonadotropin (HCG) hormone in your body. HCG is only produced during pregnancy, and lower levels may suggest the possibility of an ectopic pregnancy since HCG levels typically surge when a fertilized egg implants in the uterus.
- Ultrasound Examination: An ultrasound uses sound waves to generate images of your body’s internal structures. Your provider will utilize this test to determine the location where the fertilized egg has been implanted.
If your provider suspects a ruptured ectopic pregnancy, they may consider performing culdocentesis, although this procedure is rarely utilized.
After your provider has verified the presence of an ectopic pregnancy and identified the implantation site of the fertilized egg, they will engage in a discussion with you about the treatment plan. It’s vital to emphasize that ectopic pregnancy is a medical emergency, and prompt treatment is of utmost importance.
How soon would you know if you have an ectopic pregnancy?
An ectopic pregnancy is usually detected during the early stages of pregnancy. Healthcare providers typically diagnose ectopic pregnancies within the first trimester, which covers the initial 12 weeks of pregnancy. However, for the majority of individuals, the awareness of having an ectopic pregnancy often occurs around the eighth week of pregnancy.
How is an ectopic pregnancy treated?
Ectopic pregnancies are managed through either medication or surgical procedures by healthcare providers.
Methotrexate for ectopic pregnancy
In certain instances, your healthcare provider may recommend the use of a medication called methotrexate to halt the growth of the fertilized egg, effectively terminating the pregnancy. It’s essential to note that this medication should not cause harm to your fallopian tubes. However, it is crucial to understand that methotrexate cannot be used if your fallopian tube has already ruptured.
Methotrexate is administered as a single injection by your healthcare provider. This approach is less invasive than surgical intervention but necessitates follow-up appointments to monitor your HCG (human chorionic gonadotropin) levels. Consistent follow-up is vital in such cases. In rare situations, a second methotrexate injection may be required if HCG levels do not decrease adequately with the initial dose. It’s advisable to engage in a discussion with your healthcare provider regarding the potential side effects and risks associated with methotrexate to be well-informed about what to anticipate.
Surgery for ectopic pregnancy
When your fallopian tube has ruptured or there is a risk of rupture, your healthcare provider will recommend surgical removal of the ectopic pregnancy. This surgery is considered an emergency and is crucial for saving your life. Typically, the procedure is performed laparoscopically, involving several small incisions in your abdominal area while you are under anesthesia. During the surgery, the surgeon may opt to either remove the entire fallopian tube with the fertilized egg still inside or extract the egg from the tube while preserving the fallopian tube itself.
