What Causes Pelvic Inflammatory Disease (PID)?

Generally, pelvic inflammatory disease (PID) may be caused by poor menstrual hygiene, decreased immunity after childbirth, ascending infection from cervicitis, postoperative infection following intrauterine procedures, or the spread of inflammation from appendicitis. If symptoms arise, prompt consultation and treatment at a reputable hospital are recommended. A detailed analysis follows:

1. Poor Menstrual Hygiene

During menstruation, the cervical os is open and the uterine cavity contains wound surfaces; inadequate hygiene allows bacterial proliferation, leading to mild pelvic inflammation. Improvement can be achieved by frequently changing sanitary products, avoiding tub bathing during menstruation, and maintaining external genital cleanliness and dryness.

2. Reduced Immunity After Childbirth

Following delivery, the cervical os remains incompletely closed and the uterine cavity retains wound surfaces, while overall immune function declines—increasing susceptibility to bacterial invasion and subsequent PID. Postpartum care should include thorough perineal hygiene, adequate rest, and dietary supplementation with high-quality protein to enhance systemic immunity.

3. Cervicitis

Pathogens colonizing the cervix proliferate continuously and ascend along the reproductive tract into the pelvis, causing pelvic tissue congestion and inflammation. Treatment may include azithromycin dispersible tablets, clarithromycin capsules, or levofloxacin tablets, as prescribed by a physician. During therapy, maintain external genital hygiene and avoid unprotected sexual intercourse.

4. Postoperative Intrauterine Infection

Intrauterine procedures such as induced abortion or intrauterine device (IUD) insertion compromise the natural defense barrier of the reproductive tract. Suboptimal sterilization or improper postoperative care may lead to secondary pelvic infection. Antibiotics—including cefdinir dispersible tablets, ornidazole tablets, or clindamycin palmitate hydrochloride dispersible tablets—may be prescribed. Severe cases may require laparoscopic pelvic adhesiolysis.

5. Appendicitis

Due to its anatomical proximity to the pelvis, inflammation of the appendix can result in inflammatory exudates spreading into the pelvic cavity, triggering secondary pelvic inflammation. Antibiotic therapy—such as amoxicillin capsules, metronidazole sustained-release tablets, or cefuroxime axetil tablets—may be administered under medical supervision. In severe cases, laparoscopic appendectomy is indicated.

In daily life, maintain proper perineal hygiene and menstrual protection; ensure adequate rest and physical recovery after childbirth and surgery; actively treat gynecological and adjacent organ infections; and undergo regular gynecological screening.
