The extent to which a patient’s menstrual period will be reduced in the case of uterine adhesions depends on the extent of the uterine adhesions and the location of the uterine adhesions. If the patient only has mild adhesions at the bottom of the uterus, the patient’s menstruation will not be affected; if the adhesions are moderate, the patient’s menstruation will be reduced by one-third to two-thirds of the original base; if the adhesions are severe, the patient’s menstruation will be very low, and it will be clear when it is dripping, or there will be no menstruation at all. If the patient’s uterine adhesions are in the middle or lower part of the uterine cavity, close to the cervical canal, minor adhesions may block the cervical canal, and even if the patient has a menstrual period, the menstrual blood will not be able to pass through the uterine cavity and cervical canal to be discharged, and the patient may suffer from amenorrhea. However, in this case, if ultrasound is performed during the patient’s menstrual period, fluid can be seen in the uterine cavity, which can be treated by cervical dilatation or hysteroscopic surgery.
