Sexually Transmitted Diseases
Pelvic inflammatory disease (PID)
The most serious and common complication of sexually transmitted diseases (STDs) among women is pelvic inflammatory disease (PID), an infection of the upper genital tract. PID can affect the uterus, ovaries, fallopian tubes, or other related structures. Untreated, PID can lead to infertility, tubal (ectopic) pregnancy, chronic pelvic pain, and other serious consequences.
PID occurs when disease-causing organisms migrate upwards from the vagina and cervix into the upper genital tract. Many different organisms can cause PID, but most cases are associated with gonorrhea and chlamydia infections, two very common STDs. Scientists have found that bacteria normally present in the vagina and cervix may also play a role.
