Complex endometrial hyperplasia is clinically serious, as some of them may become cancerous. Such patients must go to the hospital regularly for the appropriate review and should be given medication for treatment, most often with progestin, to make the endometrium shed regularly and reduce the possibility of hyperplasia. If there is no other discomfort, it is best to have another diagnostic curettage six months after surgery to find out if the complex endometrial hyperplasia has shown improvement or reached a cure with the help of medication, and regular review is very important for such patients. In addition, if there is a change in the volume of menstruation, a change in the timing of menstruation, a change in the menstrual cycle or irregular vaginal bleeding, it is important to have a timely review at the hospital.
