( PID ) CAUSES, SYMPTOMS AND TREATMENT

Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. It most often occurs when sexually transmitted bacteria spread from your vagina to your uterus, fallopian tubes or ovaries.

Pelvic inflammatory disease
Pelvic inflammatory disease (PID) is an infection of one or more of the upper reproductive organs, including the uterus, fallopian tubes and ovaries. Untreated can cause scar tissue and pockets of infected fluid (abscesses) to develop in the reproductive tract, which can cause permanent damage.

The signs and symptoms of pelvic inflammatory disease can be subtle or mild. Some women don't experience any signs or symptoms. As a result, you might not realize you have it until you have trouble getting pregnant or you develop chronic pelvic pain.

Symptoms
The signs and symptoms of pelvic inflammatory disease might be mild and difficult to recognize. Some women don't have any signs or symptoms. When signs and symptoms of pelvic inflammatory disease (PID) are present, they most often include:

1. Pain — ranging from mild to severe — in your lower abdomen and pelvis
2. Unusual or heavy vaginal discharge that may have an unpleasant odor
3. Unusual bleeding from the vagina, especially during or after sex, or between periods
4. Pain during sex
5. Fever, sometimes with chills
6. Painful, frequent or difficult urination

Causes

Many types of bacteria can cause PID, but gonorrhea or chlamydia infections are the most common. These bacteria are usually acquired during unprotected sex.

Less commonly, bacteria can enter your reproductive tract anytime the normal barrier created by the cervix is disturbed. This can happen during menstruation and after childbirth, miscarriage or abortion. Rarely, bacteria can also enter the reproductive tract during the insertion of an intrauterine device (IUD) — a form of long-term birth control — or any medical procedure that involves inserting instruments into the uterus.

Risk factors

A number of factors might increase your risk of pelvic inflammatory disease, including:

• Being sexually active and younger than 25 years old
• Having multiple sexual partners
• Being in a sexual relationship with someone who has more than one sex partner
• Having sex without a condom
• Douching regularly, which upsets the balance of good versus harmful bacteria in the vagina and might mask symptoms

See your health care provider or seek urgent medical care if you experience:

• Severe pain low in your abdomen
• Nausea and vomiting, with an inability to keep anything down
• Fever, with a temperature higher than 101 F (38.3 C)
• Foul vaginal discharge

If you have signs and symptoms of PID that aren't severe, still see your provider as soon as possible. Vaginal discharge with an odor, painful urination or bleeding between periods can also be symptoms of a sexually transmitted infection (STI). If
