Pelvic Inflammatory Disease (PID) is an infection of the female reproductive organs, including the uterus, fallopian tubes, and ovaries. It is primarily caused by sexually transmitted infections (STIs), particularly chlamydia and gonorrhea. However, other bacteria can also contribute to the development of PID.

Symptoms of PID can vary but often include lower abdominal pain, abnormal vaginal discharge, irregular menstrual bleeding, and pain during intercourse. In some cases, women may experience fever, chills, or nausea. If left untreated, PID can lead to serious complications, including chronic pelvic pain, infertility, and ectopic pregnancy.

Diagnosis typically involves a pelvic examination, blood tests, and imaging studies, such as ultrasounds. Treatment generally consists of antibiotics to clear the infection, and in severe cases, hospitalization may be necessary. Preventive measures include practicing safe sex, regular STI screenings, and prompt treatment of any infections.
