Pelvic inflammatory disease (PID) is the ascent of bacteria from the vagina or cervix resulting in infection of the reproductive organs eg uterus, fallopian tubes, ovaries. It may also be a complication of sexually transmitted infections.
The most common symptoms of PID are lower abdominal pain (crampy or dull) that usually starts a few days after the onset of the last menstrual period, dyspareunia, abnormal vaginal or cervical discharge, postcoital or irregular vaginal bleeding, dysuria, fever, nausea and vomiting, although some have minimal symptoms or silent pelvic inflammatory disease.
