What is Pelvic Inflammatory Disease?
Dr. Apple Duenas-Cepedoza
Pelvic Inflammatory Disease (PID) is a serious infection of a woman’s reproductive organs—the uterus, fallopian tubes, and ovaries. It usually starts when bacteria from the vagina or cervix travel upward into the pelvis. If caught late, PID can affect fertility for life. The good news is that it is largely preventable and treatable. The bad news? If ignored, it can lead to life-threatening emergencies.
Who is at risk? PID is most often caused by sexually transmitted infections (STIs), specifically chlamydia and gonorrhea. Risk increases with multiple sexual partners, a new partner, or a history of STIs. Douching is also risky, as it pushes bacteria upward. Finally, having an intrauterine device (IUD) inserted carries a small risk of infection in the first few weeks, though that risk is very low for women without existing STIs.
How is it diagnosed? The challenge is that PID can be “silent.” Many women have mild or no symptoms. However, classic signs include dull pelvic or lower belly pain, abnormal vaginal discharge with a bad odor, irregular bleeding, painful urination, fever (sometimes with chills), and pain during sex. During a pelvic exam, tenderness when the cervix or ovaries are touched is a strong clue.
In many local clinics and public hospitals, advanced DNA-based tests (like PCR) may not be readily available or affordable. Instead, doctors rely on a combination of:
· History and physical exam – Your symptoms and the tenderness on examination.
· Gram staining – A quick, inexpensive test where discharge is placed on a slide and stained to look for bacteria under a microscope. It can show the presence of white blood cells and certain bacteria, such as gonorrhea.
· Culture and sensitivity – A sample of discharge is sent to a laboratory to grow the bacteria. This takes a few days but is valuable because it also tells the doctor which antibiotic will work best (based on sensitivity).
Sometimes an ultrasound is ordered to check for abscesses (pockets of pus). There is no single perfect test, so diagnosis relies on the doctor’s clinical judgment. That is why a face-to-face consultation with an obstetrician-gynecologist or a general practitioner is essential. Self-medicating with leftover antibiotics or relying on online advice can delay proper treatment and lead to complications.
A critical note about Pap smears. Many women mistakenly believe that a Pap smear tests for STIs. It does not. The Pap smear is a screening test for cervical cancer. It cannot detect chlamydia, gonorrhea, or other bacteria that cause PID. Having a “normal” Pap smear does not mean you are free of STIs. To check for STIs, you need a separate test, such as a Gram stain or culture. Do not skip your regular check-up just because your Pap result was normal.
What is the treatment? PID is treated with antibiotics. Because the exact bacteria are often unknown, a typical treatment course involves two weeks of multiple oral antibiotics. It is *critical* that sexual partners get treated too; otherwise, the infection will be passed back and forth. Sex should be avoided until treatment is finished and symptoms resolve. Severe cases may require hospitalization for intravenous antibiotics.
What happens if PID is left untreated? The infection can spread and form a tubo-ovarian abscess—a collection of pus in the fallopian tube and ovary. This abscess can rupture, leading to sepsis (a life-threatening whole-body response to infection). Sepsis causes dangerously low blood pressure and organ failure and can be fatal. In these advanced cases, antibiotics alone are not enough. Surgery becomes necessary. A surgeon may need to drain the abscess. In severe, repeated, or widespread infections, removal of one or both ovaries (oophorectomy) or a total hysterectomy (removal of the uterus and sometimes the cervix) may be the only way to save the patient’s life. These surgeries end fertility permanently.
When to seek help immediately. Do not wait if you notice unusual vaginal discharge (especially yellow, green, or foul-smelling) combined with hypogastric pain (lower belly pain, just above the pubic bone) and pain during sex. This specific trio of symptoms is a red flag for PID. See a doctor or go to your nearest health center or barangay health station as soon as possible—within 24 to 48 hours. Early treatment with antibiotics can prevent abscesses, sepsis, and the need for major surgery.
Prevention is key. Using condoms consistently, having only one faithful partner, getting tested for STIs regularly (especially if you are sexually active and under 25 or have a new partner), and avoiding douching are effective preventive steps. A Pap smear remains a critical, life-saving test for cervical cancer and should not be skipped—but it should never be relied upon for STI detection. For that, see a doctor for a proper pelvic exam and laboratory tests. Your reproductive health is too important to ignore. When in doubt, get checked out.
