What happens in an ectopic pregnancy

Answers

Answer:

In ectopic pregnancy the fertilized egg is established outside the womb.

Explanation:

Ectopic pregnancy is any pregnancy in which the fertilized egg is implanted in a place other than the bottom of the uterine cavity. As the fallopian tubes or tubes, ovaries, cervix and abdominal cavity. Ectopic pregnancy occurs in 1% of pregnancies and is usually caused by an injury to the fallopian tubes, which causes narrowing and / or obstruction and prevents the passage of the fertilized egg to the uterus.

Symptoms usually appear between the 6th and 10th weeks of gestation, which may include: menstrual delay, pelvic pain, vaginal bleeding, nausea, dizziness, and diarrhea. If the pregnancy is advanced, the tube may rupture and cause complications such as internal bleeding. In this case, treatment should be performed with emergency surgery due to the life-threatening mother.

In an ectopic pregnancy, the fetus is formed and continues to grow somewhere outside of the uterus. The movement of the egg could be blocked or slowed through the fallopian tubes which may cause this to happen.
