Ectopic pregnancy

An ectopic pregnancy is a when an embryo sticks to somewhere outside the uterus. In a normal pregnancy, the embryo sticks itself into the wall of the uterus.  The uterus is the only place in the body where an embryo can grow into a fetus.

Most ectopic pregnancies happen in a Fallopian tube (one of the two tubes that connect the ovaries and the uterus).  For this reason, ectopic pregnancies are often called tubal pregnancies.  Rarely, ectopic pregnancies can happen in an ovary or in the cervix.A.D.A.M Editorial Board. "Ectopic Pregnancy." PubMed Health. U.S. National Library of Medicine, 18 Nov. 0000. Web. 21 May 2012.  

Ectopic pregnancies cannot become normal pregnancies, and will not result in a baby.  They can also cause serious health problems for the mother.


 Risk Factors 
Risk factors (things that make a woman more likely to have an ectopic pregnancy) include:Mayo Clinic Staff. "Ectopic Pregnancy: Risk Factors." Mayo Clinic. Mayo Foundation for Medical Education and Research, 09 Feb. 2012. Web. 21 May 2012.
 Having an ectopic pregnancy before
 Pelvic inflammatory disease (PID)
 Damage to the Fallopian tubes caused by surgery
 Fallopian tubes that are not a normal shape
 Getting pregnant after having a tubal ligation or while an IUD is in place.

 Symptoms 
At first, there may be no symptoms.  A woman may not even know she is pregnant at this point.  Sometimes she might have pain in her pelvis, or bleeding from her vagina.Mayo Clinic. "Ectopic Pregnancy: Symptoms." Mayo Clinic. Mayo Foundation for Medical Education and Research, 09 Feb. 2012. Web. 21 May 2012.

But once the embryo has grown for about 6 to 8 weeks, it gets large enough to make the Fallopian tube break open.  This is a medical emergency, and can kill a woman. Once the Fallopian tube has ruptured, it will start to bleed into the abdomen.  Symptoms will include:Mayo Clinic. "Ectopic Pregnancy: Symptoms." Mayo Clinic. Mayo Foundation for Medical Education and Research, 09 Feb. 2012. Web. 21 May 2012.
 Pain that starts very quickly and is very sharp.  The pain will be right above the pubic area, but only on one side at first.
 After a while, the pain will spread to the rest of the abdomen.  As the Fallopian tube bleeds, the blood irritates the rest of the abdomen and causes pain.
 Eventually, the woman can lose so much blood by bleeding into her abdomen that she can faint, go into shock, or die.Mayo Clinic. "Ectopic Pregnancy: Symptoms." Mayo Clinic. Mayo Foundation for Medical Education and Research, 09 Feb. 2012. Web. 21 May 2012.

 Diagnosis and Treatment 
A physician can do an exam of the pelvis to test for sensitivity and pain, to figure out if a woman has an ectopic pregnancy. There are also blood tests for the pregnancy hormone hCG. In a normal pregnancy, the hGC levels double every day.  Low levels are evidence of a problem, like an ectopic pregnancy. An ultrasound can also be used to see if the embryo is implanted in the uterus or not.

There are two main ways to treat an ectopic pregnancy if it is diagnosed before the Fallopian tube ruptures. The first is with the medicine methotrexate.  If it is given early enough, it can cause an abortion and end the pregnancy. The second is with a surgery called a laparoscopy (a surgery done with a laser).  The surgeon makes a small cut in the belly and removes the embryo. A laparoscopy is done after the first few weeks of the pregnancy.Healthwise Staff. "Ectopic (Tubal) Pregnancy Causes, Symptoms, Diagnosis, Treatment and Prevention." WebMD. WebMD, Jan. 2009. Web. 22 May 2012.

Once the Fallopian tube ruptures, emergency surgery is needed to fix the broken Fallopian tube and remove the blood from inside the abdomen.  The patient may also needed to be treated for blood loss.

 Results 
An ectopic pregnancy cannot become a baby. But it can have effects on future pregnancies and fertility. Because in an ectopic pregnancy the embryo usually grows in a Fallopian tube, the Fallopian tube can be damaged.  This makes it more likely for another embryo to get stuck there. The likeness of another ectopic pregnancy depends on the amount of damage to the Fallopian tube, and the health of the tubes. However, even after a ectopic pregnancy, it is entirely possible to have a normal pregnancy.Healthwise Staff. "Fertility After Ectopic Pregnancy." WebMD. WebMD, 03 May 2000. Web. 22 May 2012.
