Pelvic Inflammatory Disease (PID) is an inflammation of the female genital tract that is usually caused by bacterial infections such as Chlamydia trachomatis and Neisseria gonorrhoeae spreading from the vagina or cervix. Left untreated, PID can cause serious complications like infertility, ectopic pregnancy, and chronic pelvic pain. Treatment involves antibiotics to eradicate the infection as well as managing symptoms. Prevention focuses on screening and treatment of sexually transmitted infections, particularly among young sexually active women.
