Pelvic Inflammatory Disease

Pelvic Inflammatory Disease

One of the most serious complications of STDs is pelvic inflammatory disease or PID. This infection can cause permanent damage to the uterus, ovaries, and fallopian tubes (seen here, swollen and red). In fact, it's the leading preventable cause of infertility in women. Symptoms include belly pain, fever, abnormal vaginal discharge, and pain during sex or urination. PID is treated with antibiotics, and in severe cases, surgery.
