Women with pelvic effusion are prone to infection in the tissues adjacent to the pelvic organs and downstream. It may lead to vaginitis, endometritis, pelvic adhesions, hydrosalpinx and blockage of fallopian tubes, which may cause infertility in severe cases. In addition, pelvic effusion can cause a series of uncomfortable symptoms in women, such as pressure pain in the adnexal area, lumbosacral pain, a feeling of swelling in the abdomen, yellowish leucorrhea, increased odor, and obvious dryness and pain in the vagina during sexual intercourse. Pelvic effusion can also cause abnormal menstruation and affect ovarian function, leading to prolonged and increased menstrual periods. Most pelvic effusion is caused by chronic pelvic inflammatory disease that is not treated in a timely manner, resulting in increased inflammation and thus increased fluid accumulation. It is recommended that women who suffer from chronic pelvic inflammatory disease in their lives should go to the hospital in time and take treatment under the guidance of their doctors according to their situation.
