Complications
By Mayo Clinic staffUntreated pelvic inflammatory disease may cause scar tissue and collections of infected fluid (abscesses) to develop in your fallopian tubes and damage your reproductive organs. Complications may include:
- Ectopic pregnancy. PID is a major cause of tubal (ectopic) pregnancy. In an ectopic pregnancy, the fertilized egg can't make its way through the fallopian tube to implant in the uterus. Ectopic pregnancies can cause massive, life-threatening bleeding and require emergency surgery.
- Infertility. PID may damage your reproductive organs and cause infertility — the inability to become pregnant after one year of unprotected sex. The more times you've had PID, the greater your risk of infertility. Delaying treatment for PID also dramatically increases your risk of infertility.
- Chronic pelvic pain. Many women with symptomatic pelvic inflammatory disease develop chronic pelvic pain that may last for months or years. Scarring in your fallopian tubes and other pelvic organs can cause pain during intercourse, exercise and ovulation.
