Pelvic inflammatory disease, or PID, is an infection of a woman's reproductive organs .
Treating PID right away is important, because PID can cause scar tissue in the pelvic organs and lead to infertility. It can also cause other problems, such as pelvic pain and tubal (ectopic) pregnancy.
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're more likely to get PID if you:
- Have a sexually transmitted infection (STI). The most common causes of PID are gonorrhea and chlamydia.
- Are at risk for STIs. If you are young and you don't use condoms when you have sex, you're more likely to get STIs. Having more than one sex partner also increases your risk for STIs.
- Have bacterial vaginosis.
- Have recently had an IUD inserted or had an abortion.
- Have had PID before.
At first, PID may not cause any symptoms. Or it 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, during bowel movements, or when you urinate. Some women also have a fever.
Even when PID causes mild or no symptoms, it can still cause serious problems. So you need to 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.
