What is pelvic inflammatory disease (PID)?

Pelvic inflammatory disease (PID) is an infection of a woman’s reproductive organs. See a picture of the organs inside the pelvis.

Treating PID right away is important, because PID can cause scar tissue in the pelvic organs and lead to infertility. It can also lead to other problems, such as pelvic pain and tubal (ectopic) pregnancy.

What causes PID?

PID is caused by bacteria entering the reproductive organs through the cervix. When the cervix is infected, bacteria from the vagina can more easily get into and infect the uterus and fallopian tubes.

You may be more likely to get PID if you:

• Have a sexually transmitted disease (STD). The most common causes of PID are gonorrhea and chlamydia.
• Are at risk for STDs. You are at higher risk for STDs if you are young and you don't use condoms when you have sex. Having more than one sex partner also increases your risk for STDs.
• Have bacterial vaginosis, which is not an STD.
• Douche.
• Have recently had an IUD inserted or had an abortion.
• Had PID before.

What are the symptoms?

At first, PID may not cause any symptoms or may cause only mild symptoms, such as bleeding or discharge from the vagina. Some women don't even know they have it. They only find out later, when they can't get pregnant or they have pelvic pain.

As the infection spreads, the most common symptom is pain in the lower belly. The pain has been described as crampy or as a dull and constant ache. It may be worse during sex, bowel movements, or when you urinate. Some women also have a fever.

How is PID diagnosed?

Even though PID causes mild or no symptoms, it can still cause serious problems. So you need to understand what put you at risk for PID or STDs and see your doctor if you have any unusual symptoms.

Your doctor will ask about your lifestyle and symptoms. He or she will examine you and do tests to see if you have PID. The test results may take some time. For this reason, your doctor will treat you for the disease before the test results are ready. Treating PID early is important to prevent problems later on.

Your doctor may test you for the most common causes of PID and may also do blood tests to look for signs of infection. Your doctor may also order an ultrasound to see if there are other possible causes of your symptoms. An ultrasound may also show if there is damage to the fallopian tubes, uterus, or ovaries from PID.

How is it treated?

To treat PID, you will need to take antibiotics. Take them as directed. If you don't take all of the medicine, the infection may come back.
