Pelvic Inflammatory Disease is very dangerous if not treated. In addition to causing infertility to over 100,000 women a year, 150 women die from the infection annually.
PID and its bacteria can get inside the fallopian tubes and slowly destroy them by beginning to turn normal tissue into scar tissue. This scar tissue then develops and obstructs any eggs from reaching the uterus. In some cases, the scar tissue is so damaged that sperm may be unable to fertilize an egg, and as a consequence a woman cannot become pregnant.
In a more hazardous situation, if the sperm is able to fertilize an egg, the egg can get stuck inside the fallopian tube because of the scar tissue blockage. When this happens, the egg begins to grow inside the tube as if it were inside the uterus. The result is an ectopic pregnancy. Ectopic pregnancies can cause a rupture of the fallopian tubes leading to severe pain, internal bleeding and even death.
In some cases chronic pelvic pain that can last for months or even years is a direct result of fallopian tube scarring.
Abstaining from sexual intercourse is the best way to prevent getting PID. Of course, if sexual intercourse cannot be avoided, limiting the number of partners to just one and/or using a clean latex condom during every sexual contact are good prevention methods.
Because untreated STDs are one of the main causes leading to PID it is imperative to get tested regularly. Getting tested and treated early for any STDs is best for preventing Pelvic Inflammatory Disease.
