What is pelvic inflammatory disease?
Pelvic inflammatory disease (PID) is a general term that refers to infection of the uterus (womb), fallopian tubes (tubes that carry eggs from the ovaries to the uterus) and other reproductive organs. It is a common and serious complication of some sexually transmitted diseases  especially chlamydia and gonorrhea. PID can damage the fallopian tubes and tissues in and near the uterus and ovaries. Untreated PID can lead to serious consequences including infertility, ectopic pregnancy (a pregnancy in the fallopian tube or elsewhere outside of the womb), abscess formation, and chronic pelvic pain.

How common is pelvic inflammatory disease?
Each year in the United States, it is estimated that more than 1 million women experience an episode of acute PID. More than 100,000 women become infertile each year as a result of PID, and a large proportion of the ectopic pregnancies occurring every year are due to the consequences of PID. Annually more than 150 women die from PID or its complications

How is pelvic inflammatory disease treated?
PID can be cured with several types of antibiotics. A health care provider will determine and prescribe the best therapy. However, antibiotic treatment does not reverse any damage that has already occurred to the reproductive organs. If a woman has pelvic pain and other symptoms of PID, it is critical that she seek care immediately. Prompt antibiotic treatment can prevent severe damage to reproductive organs. The longer a woman delays treatment for PID, the more likely she is to become infertile or to have a future ectopic pregnancy because of damage to the fallopian tubes.

Because of the difficulty in identifying organisms infecting the internal reproductive organs and because more than one organism may be responsible for an episode of PID, PID is usually treated with at least two antibiotics that are effective against a wide range of infectious agents. These antibiotics can be given by mouth or by injection. The symptoms may go away before the infection is cured. Even if symptoms go away, the woman should finish taking all of the prescribed medicine. This will help prevent the infection from returning. Women being treated for PID should be re-evaluated by their health care provider two to three days after starting treatment to be sure the antibiotics are working to cure the infection. In addition, a woman's sex partner(s) should be treated to decrease the risk of re-infection, even if the partner(s) has no symptoms. Although sex partners may have no symptoms, they may still be infected with the organisms that can cause PID.

Hospitalization to treat PID may be recommended if the woman
(1) is severely ill (e.g., nausea, vomiting, and high fever);
(2) is pregnant;
(3) does not respond to or cannot take oral medication and needs intravenous antibiotics;
(4) has an abscess in the fallopian tube or ovary (tubo-ovarian abscess). If symptoms continue or if an abscess does not go away, surgery may be needed. Complications of PID, such as chronic pelvic pain and scarring are difficult to treat, but sometimes they improve with surgery.
