Pelvic inflammatory disease (PID) is a serious infection of the female reproductive organs. These include the uterus, ovaries, and fallopian tubes. PID can cause scar tissue to form in the pelvis and fallopian tubes. This damage may result in infertility , a future tubal pregnancy , or chronic pelvic pain.

PID is caused by bacteria that travel to the reproductive organs. A single bacteria or mixture of several bacteria may cause the infection. The most common bacteria that initiate PID are gonorrhea and chlamydia .

A risk factor is something that increases your chance of getting a disease or condition. Risk factors include:

• Current or previous sexually-transmitted disease (STD)
• Multiple sex partners
• Sexual intercourse with a partner who has an STD
• Intercourse without the protection of a condom
• Age: 15-24 years old
• Use of an intrauterine device (IUD) for birth control—This does not increase the risk of getting an STD, but can accelerate the course of PID.

Women with PID do not always have symptoms. However, if symptoms do occur, they may include:

• Pain in the lower abdomen
• Vaginal discharge with a foul odor
• Fatigue
• Fever
• Nausea or vomiting
• Painful intercourse
• Painful urination
• Irregular menstrual bleeding

If you suspect PID, or have any symptoms, see your doctor immediately.

Because symptoms are often subtle or nonexistent, PID can be difficult to diagnose. There are no specific tests for PID.

If PID is suspected, the doctor will ask about your symptoms, as well as your sexual history, partners, and birth control methods. The doctor may perform a general physical exam, as well as a pelvic exam. The pelvic exam is key to making the diagnosis. Samples from the vagina or cervix may be taken to help diagnose the problem.

Tests may include:

• Cultures of the cervix—to test for STD organisms
• Blood test—to check pregnancy status and to check for infection
• Ultrasound —a test that uses sound waves to visualize the inside of the body
• Laparoscopy —insertion of a thin, lighted telescopic tube through a small incision in the abdomen to look at the reproductive organs

The primary treatment for PID is antibiotics. Your doctor may prescribe more than one type of antibiotic to treat the problem. Finish the entire dose of each medication, even if your symptoms disappear during treatment. Rest is also an essential part of the treatment for PID.

You may be hospitalized if the diagnosis is uncertain, you do not improve, or your symptoms are severe. In the hospital, antibiotics can be given by vein. In certain situations, surgery may be required to remove infected or damaged tissue.

If you are diagnosed with PID, follow your doctor's instructions .
