Pelvic fluid in women can be divided into physiological and pathological ones, among which physiological pelvic fluid is more beneficial to the body, while pathological pelvic fluid is mainly harmful to women’s body. The main hazards include long-term abdominal pain, dysmenorrhea that affects women’s normal life, uterine adhesions and even infertility. First of all, most of the pathological pelvic fluid is caused by inflammation of the pelvis. Long-term inflammation of the pelvis leads to serious inflammatory cell infiltration and increased inflammatory exudation to form fluid. The presence of a large amount of pelvic fluid can stimulate the pelvic cavity or cause pelvic congestion, which can lead to persistent abdominal pain, and also affect menstruation, leading to dysmenorrhea and affecting women’s quality of life. Secondly, the long-term presence of pelvic fluid provides favorable conditions for the growth and proliferation of inflammatory cells, which can aggravate the original inflammatory reaction, and the long-term inflammation may lead to pelvic scar adhesions, which may lead to female infertility if it affects the fallopian tubes and leads to tubal adhesions and blockage of the fallopian tubes. If the pelvic fluid is deeper and accompanied by uncomfortable symptoms, it should be treated promptly to avoid delays.
