Ectopic pregnancy occurs when the embryo implants outside the uterus.
In 95% of cases, the embryo implants in a fallopian tube, which is why
this condition is often termed a "tubal pregnancy."
Since the fallopian tubes are not large enough to accommodate a growing
embryo, the pregnancy cannot continue normally. If identified early,
the embryo is removed. In some cases, the embryo grows until the
fallopian tube is stretched so much that the tube ruptures.
Rupture of the tube is a medical emergency that requires immediate medical attention because it can result
in severe hemorrhaging.
An ectopic pregnancy is a potentially life-threatening condition.
Symptoms include:
sudden persistent pain in the lower abdomen, usually to one side
bleeding and abdominal pain after a missed or light period
persistent fainting or dizziness (could signal internal bleeding)
