The first thing you need to do is to find out the cause of the absence of menstruation due to uterine fluid. There are two possible causes of uterine fluid retention: first, the blood inside the cervical endocervical adhesions can not flow out, due to the damage of the cervical endocervical opening after abortion surgery or intrauterine operation surgery, coupled with inflammatory factors leading to adhesions, so that the menstrual blood can not be discharged smoothly, and need to be surgically separated from the adhesions; second, due to the inflammation of the endometrium leading to increased inflammatory exudate in the uterine cavity, some of the endometrium has adhesions that affect the uterine contraction and discharge of menstrual blood. Secondly, due to endometrial inflammation, the inflammatory exudate in the uterine cavity increases, and some endometrial adhesions affect uterine contraction and menstrual blood discharge. If this is the case, it should be treated with anti-inflammatory treatment or endometrial adhesion detachment surgery. In addition to taking appropriate treatment measures for the cause of the disease, it is also necessary to pay attention to nutrition, moderation of labor and leisure, avoiding exposure to cold, maintaining a cheerful and optimistic state of mind, and strengthening one’s own resistance.
