If menstrual dripping occurs at the age of 51, it is most likely that it is clinically caused by menopausal hemorrhage. Since this age has already entered the perimenopausal stage, the gradual decline of ovarian function and hormone levels in clinical practice can lead to functional uterine bleeding during menopause. However, it is also recommended that ultrasound and gynecological examination should be performed to rule out the possibility of organic lesions. If there is no organic pathology, progesterone can be used for treatment. Usually the vaginal bleeding will stop about 24-48 hours after the administration of the drug. Then it is also recommended that after the vaginal bleeding is completely cleared, ultrasound examination is done to understand the condition of the endometrium and to rule out the possibility of organic lesions.
