Ectopic Pregnancy

Pregnancy starts when a sperm fertilizes an egg. Usually, the fertilized egg, called a zygote, attaches to the lining of the uterus, preparing for a healthy pregnancy. However, sometimes the zygote implants and grows somewhere other than the uterus's main body. This is called an ectopic pregnancy.

Most often, an ectopic pregnancy happens in a fallopian tube. These tubes connect the ovaries (where eggs are produced) to the uterus. When the fertilized egg implants and grows in a fallopian tube, it's called a tubal pregnancy. Less commonly, an ectopic pregnancy can occur in other areas, such as the ovary, the abdomen (the space holding organs), or even the cervix (the lower part of the uterus that connects to the vagina).

An ectopic pregnancy can't develop into a normal pregnancy. The growing zygote can't survive in that location. If left untreated, the growing tissue can cause dangerous internal bleeding. This is a serious medical condition requiring immediate attention.

Sometimes, a pregnancy isn't developing where it should. This is called an ectopic pregnancy. At first, you might not have any noticeable symptoms. However, some women experience the typical early pregnancy signs like a missed period, sore breasts, and feeling sick to their stomach.

If you take a pregnancy test, it will likely show up as positive. But a pregnancy that starts outside the uterus (the womb) can't develop normally.

As the fertilized egg grows in the wrong place, you'll likely start to notice more obvious signs and symptoms.

Get immediate medical attention if you think you might have an ectopic pregnancy. This is a serious condition where a pregnancy develops outside of the uterus, usually in a fallopian tube. Early diagnosis and treatment are crucial.

Signs of an ectopic pregnancy can include:

• Sharp pain in your lower stomach (abdomen) or pelvis, along with bleeding from your vagina. This pain might be sudden and intense. The bleeding could be light or heavy.
• Feeling very dizzy or lightheaded, or even passing out. This is a sign your body isn't getting enough blood flow.
• Pain in your shoulder. This unusual pain can happen because of the buildup of blood irritating the nearby nerves.

If you experience any of these symptoms, seek immediate medical help. Don't delay. Prompt treatment is essential for preventing complications.

A tubal pregnancy is a type of ectopic pregnancy. This means a fertilized egg implants and grows outside of the uterus, most often in a fallopian tube. The fallopian tubes are the pathways that carry eggs from the ovaries to the uterus. Sometimes, these tubes are damaged or have an unusual shape, which can prevent the fertilized egg from traveling to the uterus. This can cause the egg to implant in the fallopian tube instead. Other possible causes include hormonal problems or issues with how the fertilized egg develops.

Factors that increase the chance of an ectopic pregnancy include:

• Previous ectopic pregnancy: If you've had an ectopic pregnancy before, you have a higher likelihood of experiencing it again. This is because the fallopian tubes, the pathways where a fertilized egg normally travels, may have been damaged during the first ectopic pregnancy.

• Infections and inflammation: Sexually transmitted infections (STIs) like gonorrhea and chlamydia can cause inflammation and scarring in the fallopian tubes and surrounding reproductive organs. This inflammation can make it harder for a fertilized egg to travel correctly, increasing the risk of an ectopic pregnancy.

• Fertility treatments: Some studies suggest that women undergoing in vitro fertilization (IVF) or similar fertility treatments might have a higher risk of ectopic pregnancy. Infertility itself can also be a contributing factor. This is likely because these procedures or conditions can sometimes affect the health of the fallopian tubes.

• Tubal surgery: Surgery to repair or treat damaged or blocked fallopian tubes can increase the risk of ectopic pregnancy. If the tubes have been repaired or reconnected, the healing process can be delicate and increase the risk of the fertilized egg implanting outside of the uterus.

• Birth control methods: While getting pregnant while using an intrauterine device (IUD) is uncommon, if pregnancy does occur with an IUD in place, it might be more likely to be ectopic. This is because IUDs can sometimes irritate the lining of the uterus or fallopian tubes. Similarly, tubal ligation (having your tubes tied), a permanent form of birth control, raises the risk of ectopic pregnancy if you become pregnant afterward. This is because the tubes have been sealed, preventing the egg from traveling to the uterus.

• Smoking: Smoking, especially around the time of conception, can increase the risk of ectopic pregnancy. The more you smoke, the greater the risk becomes. Smoking can damage the fallopian tubes and affect their ability to properly transport the fertilized egg.

It's important to remember that these factors increase the possibility of an ectopic pregnancy, but they don't guarantee it. If you have any concerns about your risk, it's essential to talk to your doctor.

A pregnancy outside the uterus, called an ectopic pregnancy, can be dangerous. It happens when a fertilized egg implants and grows somewhere other than the inside of the uterus, often in a fallopian tube. This can cause the fallopian tube to stretch and potentially rupture. If the tube ruptures, it can lead to severe bleeding. This bleeding can be life-threatening if not treated quickly.

Preventing ectopic pregnancies is tricky; there's no surefire way to avoid them. However, there are steps you can take to lessen your chances.

One important thing is to take steps to protect yourself from sexually transmitted infections (STIs). Having fewer sexual partners and using condoms during sex can help. STIs can sometimes lead to pelvic inflammatory disease (PID), and PID can increase the risk of an ectopic pregnancy.

Smoking is also a factor. If you smoke, quitting before you try to get pregnant is a good idea. Smoking can affect your overall health and potentially impact your ability to have a healthy pregnancy, including increasing the risk of an ectopic pregnancy.

A pelvic exam can help your doctor check for pain, tenderness, or unusual lumps in your fallopian tubes or ovaries. However, a simple pelvic exam alone can't tell if you have an ectopic pregnancy. To diagnose this, further tests are needed.

To confirm pregnancy, your doctor will order a blood test called a human chorionic gonadotropin (hCG) test. This test measures a hormone that increases during pregnancy. This blood test is often repeated every few days to monitor the hCG levels. This helps determine if you're pregnant and if the pregnancy is developing normally. The ultrasound can then confirm or rule out an ectopic pregnancy, typically around five to six weeks after conception.

A transvaginal ultrasound is a common test used to see where the pregnancy is located. For this, a small, wand-like device is gently inserted into your vagina. This device sends sound waves that create images of your uterus, ovaries, and fallopian tubes on a nearby screen. These images help your doctor see the location and the condition of these organs.

An abdominal ultrasound, where the wand is moved over your belly, might also be used. This is sometimes helpful to check for pregnancy or to see if you have any internal bleeding.

During a transvaginal ultrasound, you lie on an exam table. A healthcare professional, like a doctor or a trained technician, inserts a small wand-like device (called a transducer) into your vagina. The sound waves produced by the transducer create detailed images of your uterus, ovaries, and fallopian tubes, which are displayed on a monitor.

A complete blood count (CBC) is often done to check for anemia (low red blood cells) or other signs of blood loss. If an ectopic pregnancy is diagnosed, your doctor might also order blood tests to determine your blood type, in case a blood transfusion is needed.

A fertilized egg needs the protective environment of the uterus to develop normally. If a pregnancy develops outside the uterus (an ectopic pregnancy), it can be dangerous. To prevent serious health problems, the abnormal tissue needs to be removed. The method used depends on the severity of the situation and how early the ectopic pregnancy is detected.

Often, an early ectopic pregnancy, without heavy bleeding, can be treated with medication called methotrexate. Methotrexate stops the growth of cells and helps dissolve the existing pregnancy tissue. This medication is injected. It's crucial that the diagnosis of an ectopic pregnancy is absolutely correct before this treatment is given.

After the injection, your doctor will check your hormone levels (using a blood test for a hormone called hCG) to see how the treatment is working. If needed, more methotrexate will be given.

If medication isn't an option or if the ectopic pregnancy is more advanced, a minimally invasive surgical procedure called laparoscopic surgery might be used. In laparoscopic surgery, a small cut is made near the belly button. A thin, tube-like tool with a camera (a laparoscope) is inserted to visualize the affected area.

There are two main types of laparoscopic surgery for ectopic pregnancies:

• Salpingostomy: The ectopic pregnancy is removed, but the fallopian tube is left intact and allowed to heal.

• Salpingectomy: Both the ectopic pregnancy and the fallopian tube containing the pregnancy are removed.

The type of surgery chosen depends on several factors: the amount of bleeding, the damage to the fallopian tube, whether the tube has ruptured, and the health of your other fallopian tube.

If there's heavy bleeding from an ectopic pregnancy, emergency surgery might be needed. This surgery could be laparoscopic or involve a larger incision (called a laparotomy). Sometimes, the fallopian tube can be saved, but often, a ruptured tube needs to be removed.
