What is an Ectopic Pregnancy? Symptoms, Causes, and Treatment

Ectopic Pregnancy

Ectopic pregnancy is a significant medical condition that can constitute a serious emergency in terms of women's health and requires early diagnosis and treatment. This condition means that the pregnancy develops outside the uterus, which is the normal site of implantation, and can be life-threatening if not intervened in a timely manner. Having accurate information about ectopic pregnancy is of critical importance for early diagnosis and treatment.

What is an Ectopic Pregnancy?

An ectopic pregnancy is a condition where the fertilized egg implants outside the uterus. In a normal pregnancy, the embryo formed after the sperm and egg are fertilized travels to the uterus and implants there to continue its development. In an ectopic pregnancy, this fertilized egg usually implants in the fallopian tubes. In rarer cases, it may also implant in the ovary, the cervix, or the abdominal cavity. The embryo cannot continue its development in an ectopic pregnancy because tissues outside the uterus are not structured to support a growing embryo. Therefore, an ectopic pregnancy does not result in a live birth. Furthermore, if not intervened in a timely manner, it can cause rupture of the fallopian tubes, internal bleeding, and life-threatening danger.

What Are the Symptoms of an Ectopic Pregnancy?

Symptoms of an ectopic pregnancy may initially resemble normal pregnancy symptoms, making early diagnosis difficult. Symptoms usually appear between the 6th and 8th weeks of pregnancy, but sometimes they may manifest earlier or later.

Early symptoms: The first symptoms of an ectopic pregnancy include a missed period and unilateral pain in the lower abdominal region. Normal pregnancy symptoms such as nausea, breast tenderness, and fatigue may also be observed. Specifically, symptoms of a 5-week ectopic pregnancy begin with spotting-type bleeding.

Vaginal bleeding: Unlike normal menstrual bleeding, bleeding in an ectopic pregnancy is usually dark brown or light red in color. This bleeding is irregular and sometimes manifests as spotting or continuous light bleeding. The amount and duration of the bleeding may vary from person to person.

Abdominal pain: The most characteristic symptom of an ectopic pregnancy is unilateral abdominal pain. This pain is usually felt on the side where the pregnancy has implanted and intensifies over time. The pain may be sharp, stabbing, or cramp-like. It may increase with movement, coughing, or sneezing.

Critical symptoms: If the ectopic pregnancy has reached the point of rupture, symptoms such as sudden onset of severe abdominal pain, shoulder tip pain, dizziness, fainting, rapid pulse, and a drop in blood pressure occur. This condition requires emergency medical intervention.

Rectal pressure sensation: Some women may experience a sensation of pressure in the rectal area. This is caused by the blood accumulation in the abdominal cavity putting pressure on the rectum.

Shoulder pain: If the pregnancy continues to grow in the fallopian tube, symptoms of internal bleeding in an ectopic pregnancy may appear. These include sudden and severe abdominal pain, fainting, low blood pressure, and shoulder pain.

What Causes an Ectopic Pregnancy?

The most important factor in the development of an ectopic pregnancy is the presence of conditions that prevent the fertilized egg from reaching the uterine cavity. This can occur due to various anatomical, infectious, or hormonal reasons. The causes of ectopic pregnancy can be listed as follows:

Fallopian tube damage: Past infections, especially sexually transmitted diseases such as chlamydia and gonorrhea, can cause scar tissue formation in the fallopian tubes. This scar tissue prevents the egg from moving within the tube and increases the risk of ectopic pregnancy.

Past surgical procedures: Previous abdominal surgeries, appendectomy, ovarian cyst operations, or fallopian tube surgeries can cause adhesions within the tube.

Endometriosis: The presence of uterine tissue in the fallopian tubes and other organs impairs tube functions and increases the risk of ectopic pregnancy.

Previous ectopic pregnancy: The risk of recurrence in women who have previously had an ectopic pregnancy ranges between 10-15%. This is related to the persistence of underlying anatomical problems.

Reproductive techniques: Assisted reproductive techniques such as IVF treatment can increase the risk of ectopic pregnancy due to multiple embryo transfer and hormonal stimulation.

Age factor: The risk of ectopic pregnancy increases in women over 35. This is related to the decrease in fallopian tube functions and hormonal changes with age.

Smoking: Smoking negatively affects the muscle movements (peristalsis) of the fallopian tubes and slows down the movement of the egg within the tube.

Intrauterine device (IUD): The use of an IUD reduces the overall risk of pregnancy, but if a pregnancy occurs, the probability of it being an ectopic pregnancy increases.

Hormonal factors: Progesterone deficiency can affect the contractile properties of the fallopian tubes, delaying the egg's arrival in the uterine cavity.

How is an Ectopic Pregnancy Diagnosed?

An ectopic pregnancy is diagnosed through a combination of clinical symptoms, physical examination, and laboratory tests. Since early diagnosis is life-saving, rapid evaluation is critical in suspicious cases. The following steps are applied for diagnosis:

Clinical evaluation: The doctor questions the patient's menstrual history, pregnancy symptoms, pain characteristics, and vaginal bleeding features in detail. The presence of risk factors (previous infections, surgical procedures, smoking) is evaluated.

Physical examination: During the gynecological examination, vaginal bleeding, cervical tenderness, the presence of an adnexal mass, and abdominal tension are investigated. Tenderness and fullness in the Pouch of Douglas can be evaluated via rectal examination.

Beta-hCG test: Levels of beta-hCG, the pregnancy hormone, increase regularly in a normal pregnancy. In an ectopic pregnancy, this increase is slow or stops. Serial beta-hCG measurements are used to monitor pregnancy development.

Ultrasonography: Transvaginal ultrasound is the most important imaging method in the diagnosis of ectopic pregnancy. While no gestational sac is seen in the uterine cavity, a mass or free fluid (blood) can be detected in the adnexal region.

Diagnostic laparoscopy: In cases where a definitive diagnosis cannot be made, direct imaging can be performed using a minimally invasive surgical method. This procedure can also be used for treatment purposes.

How is an Ectopic Pregnancy Treated?

Ectopic pregnancy treatment is determined based on factors such as the size of the pregnancy, its location, the patient's clinical condition, and beta-hCG levels. Treatment options can be listed as follows:

Medical treatment: In cases detected in the early stages, methotrexate, known as the ectopic pregnancy injection, is administered to terminate the pregnancy. This drug stops cell division, allowing the pregnancy tissue to disappear.

Surgical intervention: In cases of tube rupture or where methotrexate is ineffective, ectopic pregnancy surgery is required. Laparoscopic (closed) surgery is generally preferred. During the operation, the tube can be opened to remove the pregnancy material (salpingostomy) or the tube can be removed entirely (salpingectomy).

Follow-up and monitoring: In some very early ectopic pregnancies, if the beta-hCG has started to drop and the patient is in a stable condition, regular follow-up can be performed without any treatment, but this approach is valid only for very carefully selected cases.

The recovery time after ectopic pregnancy surgery varies depending on the type of procedure performed. After laparoscopic surgery, most patients are discharged within a few days and can return to their normal activities within 1-2 weeks. If open surgery has been performed, this period may be longer. Rest and check-ups recommended by the doctor should not be neglected.

Frequently Asked Questions

An ectopic pregnancy usually manifests itself with symptoms such as groin pain accompanying a missed period, spotting-type vaginal bleeding, shoulder pain, dizziness, and fatigue. The most accurate diagnosis is made with a blood test (beta-hCG) and transvaginal ultrasonography. The risk of ectopic pregnancy is higher in those who have had pelvic infections, those who have previously experienced an ectopic pregnancy, those undergoing IVF treatment, those with structural defects in their tubes, and women who smoke. Additionally, if a pregnancy occurs in those using an IUD, the probability of an ectopic pregnancy may increase. Protecting against sexually transmitted diseases, ensuring early treatment of pelvic infections, quitting smoking, and not neglecting regular gynecological check-ups before pregnancy can help reduce the risk of ectopic pregnancy. It is also important for women who have previously had an ectopic pregnancy to consult with a doctor before a planned pregnancy. An ectopic pregnancy usually manifests itself with unilateral and severe pain in the groin area. This pain can be progressive and sometimes radiates to the shoulder. In serious cases such as tube rupture, the pain becomes sudden and very severe. A beta-hCG test performed in the blood can reveal the suspicion of an ectopic pregnancy. While the hormone level rises regularly and rapidly in a normal pregnancy, this rise is slow or irregular in an ectopic pregnancy, but evaluation with ultrasound imaging is required for a definitive diagnosis. In rare cases, an ectopic pregnancy can terminate on its own, especially if beta-hCG levels have started to drop. This is not always a safe process. Due to the risk of internal bleeding, monitoring under doctor supervision is essential. Women who have previously had an ectopic pregnancy are at a higher risk of experiencing another one. Therefore, it is important to consult with a doctor before becoming pregnant again and to be closely monitored in the early stages of pregnancy. A missed period is seen in an ectopic pregnancy just as it is in a normal pregnancy. Symptoms related to the pregnancy appear shortly after, along with problems such as pain and bleeding. Therefore, if there is pain or bleeding along with a delayed period, an ectopic pregnancy should be suspected. Sexual intercourse is not recommended for a person who is suspected of having or has been diagnosed with an ectopic pregnancy because the increase in pressure during intercourse can increase pain or trigger the risk of tube rupture. Sexual intercourse should be paused until the diagnosis and treatment process is completed. The specialist that people suspected of having an ectopic pregnancy should consult is an obstetrics and gynecology (gynecology) specialist. Gynecologists both manage the diagnostic process and determine the appropriate treatment method. If there are emergency symptoms, it is recommended to go directly to the emergency department.
