Endometritis is an inflammation or irritation that takes place in the uterus. Commonly known as pelvic inflammatory disease, endometritis is caused by sexually transmitted diseases (STD), through a change in normal vaginal bacteria and from certain surgical procedures. According to the Mayo Clinic, it's not uncommon for women to not even know that they have endometritis unless they are trying to get pregnant or develop a chronic pain in their pelvis.
Sexually Transmitted Disease
Chlamydia or gonorrhea are frequently found to be the cause of endometritis. Spread through sexual contact with an infected person, STDs can be prevented by using a condom or treated with antibiotics. Sexual contact with certain types of contraception, like an intrauterine device, can also contribute to the risk of infection.
Vaginal Bacteria
All women have a mixture of bacteria in their vagina. It is when the natural composition of the bacteria changes that the risk of endometritis is increased. This is most common after pregnancy and can be quite difficult to treat.
Surgery
Surgical procedures that go through the uterus also increase the risk of getting endometritis. Because of the potential problems caused by the infection, like infertility and septic shock, providers must always surgically-sterilize any instruments being used before the procedure.
