Pelvic Inflammatory Disease

Pelvic Inflammatory Disease

Definition:
Pelvic inflammatory disease (PID) is a general term that refers to infection of the uterus, fallopian tubes, and other reproductive organs in women. PID is a common and serious complication of some sexually transmitted diseases, especially Chlamydia and Gonorrhea, when left untreated. Approximately 4.2% of US women report being treated for PID.1

Risks:
Often goes undiagnosed and can lead to further serious infection. PID is a cause of infertility, ectopic pregnancy (a pregnancy growing outside the uterus, typically in a fallopian tube), and chronic pelvic pain. Women with PID experience:

  • Ectopic pregnancy 6 times more often.
  • Infertility, from 8% increased risk after one episode of PID to 40%  after three episodes.
  • Chronic pelvic pain, 18% greater risk after one episode of PID.2

If left untreated:
Can cause permanent damage to female reproductive organs.
