An ectopic pregnancy is an early pregnancy that occurs outside of the normal location (uterine lining) for a developing pregnancy. Most ectopic pregnancies occur in the Fallopian tubes. An ectopic pregnancy cannot progress normally and typically results in the death of the embryo or fetus.

    An ectopic pregnancy is a pregnancy located outside the inner lining of the uterus. The Fallopian tubes are the most common locations for an ectopic pregnancy. The characteristic three symptoms of ectopic pregnancy are abdominal pain, absence of menstrual periods (amenorrhea), and vaginal bleeding. However, only about 50% of women have all three of these symptoms.

    Risk factors for ectopic pregnancy include previous ectopic pregnancies and conditions (surgery, infection) that disrupt the normal anatomy of the Fallopian tubes.

    The major health risk of an ectopic pregnancy is rupture, leading to internal bleeding.

    Ectopic pregnancy occurs in 1%-2% of all pregnancies.

    Diagnosis of ectopic pregnancy is usually established by blood hormone tests and pelvic ultrasound.

    Treatment options for ectopic pregnancy include both surgery and medication.
