The definition of pelvic inflammatory disease is the inflammation of various organs in a woman’s pelvic cavity (such as the uterus, ovaries, fallopian tubes, etc.). It is a common gynecological disease. Pelvic inflammatory disease is caused by pathogens entering the vagina and entering the pelvic cavity through the cervix, causing infection. Usually, pathogens happen to enter the uterus along the vagina while the patient is sleeping or are transmitted by the male partner, causing the infection to gradually spread to the pelvic organs. This disease can cause patients a lot of inconvenience and pain. Symptoms of pelvic inflammatory disease Symptoms of pelvic inflammatory disease
