Pelvic inflammatory disease (PID)
Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. It usually occurs when sexually transmitted bacteria spread from your vagina to your uterus, fallopian tubes or ovaries.
Pelvic inflammatory disease often causes no signs or symptoms. As a result, you might not realize you have the condition and get needed treatment. The condition might be detected later if you have trouble getting pregnant or if you develop chronic pelvic pain.
