Uterine adhesions have little to do with pelvic inflammatory disease. In clinical practice, they are caused by damage to the endometrium during the operation of the uterine cavity. In clinical practice, it is recommended that once the adhesions are detected, a separation operation should be performed as soon as possible to restore menstruation and to recover the adhesions. It is best to go to the hospital for hysteroscopy at any time between 3 and 7 days after menstruation or in case of complete adhesions leading to amenorrhea, to separate the adhesions and insert a birth control ring into the uterine cavity, and then to take oral supplementation for three menstrual cycles after the operation, so that the damaged endometrium can be restored accordingly.
