Sexually transmitted infections (STIs) can happen to anyone who is sexually active. While appropriate screenings can detect them, it is not uncommon for STIs to present few or mild symptoms. For this reason, young women who are sexually active are encouraged to see a gynecologist every year for routine screenings. The immediate goal of screening for STIs is to identify and treat patients who have STIs before the infections are able to cause any additional complications. Secondary infections, such as Pelvic Inflammatory Disease (PID), can develop if STIs are left untreated for an extended period of time. PID usually occurs when a bacteria from a sexually transmitted infection spreads from the vaginal area to the uterus, fallopian tubes or ovaries. Untreated PID can cause complications, such as recurring pelvic pain, ectopic pregnancies, and even infertility. When diagnosed early on, however, many of these complications can be avoided.
