Pelvic inflammatory disease (PID)

Pelvic inflammatory disease, or PID, is an infection of your womb, fallopian tubes or ovaries, which happens when bacteria spreads from your vagina or cervix. It is usually caused by a sexually transmitted infection (STI) such as chlamydia or gonorrhoea, but can also happen after surgery, pregnancy, or having an IUD or IUS fitted.

PID causes pelvic pain and vaginal discharge, and sometimes fever or abnormal bleeding. If you have any of these symptoms, see a doctor and ask to be tested.

If PID is not treated early, it can lead to infertility or an ectopic pregnancy (a baby growing outside of the womb) as well as long-term pelvic pain.

You can read more about PID in this this leaflet from the British Association for Sexual Health and HIV.
