Ectopic pregnancy refers to a condition where the fertilized egg implants outside the uterus, usually in the fallopian tube. Synonyms for ectopic pregnancy include tubal pregnancy, extrauterine pregnancy, and malpositioned pregnancy. Other terms that can be used to describe this condition include nonviable pregnancy, abnormal pregnancy, and failed pregnancy. Ectopic pregnancies can be life-threatening, and symptoms may include abdominal pain, vaginal bleeding, and dizziness. Certain risk factors, such as previous ectopic pregnancy or pelvic inflammatory disease, may increase the likelihood of experiencing an ectopic pregnancy. Early diagnosis and treatment are critical to reducing the risks and complications associated with this condition.
