Clinical Information
  • A condition in which the female reproductive organs are inflamed. It may affect the uterus, fallopian tubes, ovaries, and certain ligaments. Pelvic inflammatory disease is usually caused by a bacterial infection. It may cause infertility and an increased risk of an ectopic pregnancy (pregnancy in the fallopian tubes).
  • A disorder characterized by an infectious process involving the pelvic cavity.
  • A spectrum of inflammation involving the female upper genital tract and the supporting tissues. It is usually caused by an ascending infection of organisms from the endocervix. Infection may be confined to the uterus (endometritis), the fallopian tubes; (salpingitis); the ovaries (oophoritis), the supporting ligaments (parametritis), or may involve several of the above uterine appendages. Such inflammation can lead to functional impairment and infertility.
  • Any pelvic infection involving the upper female genital tract beyond the cervix.
  • Pelvic inflammatory disease (pid) is an acute or chronic inflammation in the pelvic cavity. It is most commonly caused by sexually transmitted diseases, including chlamydia and gonorrhea that have ascended into the uterus, fallopian tubes, or ovaries as a result of intercourse or childbirth, or of surgical procedures, including insertion of iuds or abortion. Pid may be either symptomatic or asymptomatic. It may cause infertility and it may raise the risk of ectopic pregnancy. Pid is a disease associated with hiv infection.

  • Pelvic inflammatory disease (pid) is an infection and inflammation of the female reproductive organs. It can scar the tubes that carry eggs from the ovary to the uterus which can lead to infertility, ectopic pregnancy, pelvic pain and other problems. Pid is the most common preventable cause of infertility in the United States. gonorrhea and chlamydia are the most common causes, but other bacteria can also cause pid.you are at risk if you
    • are sexually active and younger than 25
    • have more than one sex partner

    some women have no symptoms. Others have pain in the lower abdomen, fever, smelly vaginal discharge, irregular bleeding or pain during intercourse. Antibiotics can cure pid.
