What Are the Risk Factors for Developing an Ectopic Pregnancy?

An ectopic pregnancy happens when a fertilized egg grows outside of the main part of the uterus, often in a fallopian tube. One major risk factor is having a past pelvic infection, like from chlamydia or gonorrhea, because these infections can cause scarring in your tubes. If you have had a previous ectopic pregnancy or surgery on your fallopian tubes, your risk may be higher, as these issues can change how the egg moves through the tube. Sometimes, treatments that help with fertility can increase the chance of an ectopic pregnancy. Other factors, such as smoking, can also raise the risk because smoking might affect the way the tube works. These factors can make it harder for the egg to move smoothly into the womb for a normal pregnancy. If you have any concerns or think you might be at risk, talking with a healthcare provider can help you better understand your chances and how to stay as healthy as possible.
