Normally, a woman’s menstruation lasts 2-8 days before it is completely over. If the period lasts for a month and does not end, this indicates that the woman may have an organic pathology of the reproductive system. For example, the most common ones are submucosal fibroids, endometrial polyps, etc., which can cause an increase in the surface area of the endometrium and can affect the normal contraction of the uterus during menstruation, causing incomplete menstruation. Some women have blood clotting disorders or abnormal liver and kidney function, which can also cause similar conditions. Other women have abnormalities in the function of the gonadal axis, resulting in an unsynchronized endometrial exfoliation and repair. For example, ovarian corpus luteum atrophy insufficiency can cause menstrual dribbling. The above information is for reference only.
